For example, when multiple objects are located very close to each other, they may be displayed overlapping each other. In such cases, the area in which the desired object can be selected may become small, or may not exist at all. As a result, with technology such as that described in Patent Document 1, there is a risk that an object other than the desired object may be selected, making it difficult to select the desired object.

The object of the present invention is to provide a selection device, selection method, and program that solves the problem that it can sometimes be difficult to select the object you want to select.

[First embodiment]
A first embodiment of the present disclosure will be described with reference to FIGS. 1 to 9. FIG. 1 is a diagram for explaining a selection system. FIG. 2 is a block diagram showing an example of the configuration of the display device 100. FIG. 3 is a diagram for explaining an example of set angle information 142.

In the first embodiment of the present disclosure, a selection system for selecting an object displayed in a virtual space will be described. In the selection system described in this embodiment, as shown in FIG. 1, an object is selected using a hand, which serves as an indicator. Furthermore, as will be described later, when the selection system determines that multiple objects are selection candidates as a result of selection using the indicator, it assigns angles to the multiple selection candidate objects, thereby setting an angle corresponding to each object. Furthermore, the processing system calculates the angle of the hand, which serves as the indicator. The processing system then determines the object to select from the selection candidates based on the setting result and the calculated angle of the indicator.

When multiple objects are determined to be selection candidates, this occurs when there is a risk of selecting the wrong object, for example, when multiple objects overlap at the position pointed to by the pointer, or when other objects exist near the object selected by the pointer (any range is acceptable). When multiple objects exist within such a predetermined range, it may be impossible to accurately select the desired object due to the objects overlapping. Therefore, the selection system performs processing to select selection candidates.

The selection system described in this embodiment includes a display device 100. The display device 100 is a selection device that displays pre-stored objects and detects a hand, which serves as a pointer, to select an object being displayed. For example, the display device 100 is an information processing device such as a head-mounted display (HMD) that is worn on the head of a user who uses the selection system. The display device 100 may be composed of multiple devices, such as a detection/selection device with a sensor and a screen display device such as AR/MR (Augmented Reality/Mixed Reality) glasses. Note that the display device 100 may be something other than one worn on the user's head, such as one that has a screen display device such as an LCD display.

Figure 2 shows an example configuration of the display device 100. Referring to Figure 2, the main components of the display device 100 include, for example, a detection unit 110, a screen display unit 120, a communication I/F unit 130, a memory unit 140, and an arithmetic processing unit 150.

The detection unit 110 includes a sensor that detects a pointer, etc. For example, the detection unit 110 includes a depth sensor, an RGB camera, etc. The detection unit 110 can also include a sensor for detecting the orientation or tilt of the display device 100. For example, the detection unit 110 can include at least one of a magnetic sensor, an acceleration sensor, a gyro sensor, etc. The detection unit 110 can also include an eye tracking sensor that detects the eye movement of a user wearing the display device 100. The detection unit 110 may also include sensors other than those exemplified above.

The screen display unit 120 is composed of a screen display device such as an LCD (Liquid Crystal Display). For example, the screen display unit 120 is a transmissive LCD display or a transmissive organic EL display. The screen display unit 120 can display various information stored in the memory unit 140 on the screen in response to instructions from the calculation processing unit 150.

The communication I/F unit 130 consists of a data communication circuit. The communication I/F unit 130 performs data communication with external devices connected via a communication line.

The memory unit 140 is a storage device such as a hard disk or memory. The memory unit 140 stores processing information and programs 143 required for various processes in the calculation processing unit 150. The programs 143 are read into the calculation processing unit 150 and executed to realize various processing units. The programs 143 are read in advance from an external device or recording medium via a data input/output function such as the communication I/F unit 130, and are stored in the memory unit 140. Examples of the main information stored in the memory unit 140 include object information 141 and set angle information 142.

Object information 141 includes information about objects to be displayed in virtual space. For example, object information 141 may include identification information for identifying the object, display content information that is information about the object itself to be displayed in virtual space, such as shape and color, and location information that indicates the location in virtual space where the object is to be displayed. Object information 141 may also include objects other than those exemplified above. Object information 141 is acquired in advance from an external device or the like via communication I/F unit 130 or the like, and is stored in storage unit 140.

The set angle information 142 indicates the relationship between the angle of the hand, which is the indicator, and each object that is a selection candidate, as set by the angle setting unit 153 described below. For example, the set angle information 142 associates information indicating the range of the indicator angle with information indicating the object assigned to that range (e.g., identification information, etc.). The set angle information 142 is generated and updated when the angle setting unit 153 assigns an object to an angle.

Figure 3 shows an example of the information indicated by the set angle information 142. For example, in the example shown in Figure 3, a spherical object is assigned to an angle between 0 degrees and less than 45 degrees, and a rectangular parallelepiped object is assigned to an angle between 45 degrees and less than 90 degrees. Furthermore, a conical object is assigned to an angle between 90 degrees and less than 135 degrees, and a star-shaped object is assigned to an angle between 135 degrees and less than 180 degrees. In this way, the set angle information 142 includes information indicating the result of assigning an angle to each object that is a selection candidate.

Note that the number of objects assigned by the set angle information 142 corresponds to the number of objects to be selected. Therefore, the number of objects assigned by the set angle information 142 is not limited to four. Furthermore, the set angle information 142 may assign an angle in a range other than 0 degrees to 180 degrees.

The arithmetic processing unit 150 has an arithmetic device such as a CPU and its peripheral circuits. The arithmetic processing unit 150 reads and executes the program 143 from the storage unit 140, thereby enabling the above hardware and the program 143 to work together to realize various processing units. The main processing units realized by the arithmetic processing unit 150 include, for example, a detection unit 151, a selection unit 152, an angle setting unit 153, an angle calculation unit 154, a determination unit 155, and a display unit 156.

The detection unit 151 detects a predetermined indicator, such as a hand, based on the results detected by the detection unit 110.

For example, the detection unit 151 detects the hand, which is the pointer, using image data acquired by an RGB camera and depth information acquired by a depth sensor. The detection unit 151 may detect the pointer using known techniques, such as pattern matching or a model acquired in advance through machine learning.

The selection unit 152 selects an object displayed in virtual space using the results of detection by the detection unit 151. For example, the selection unit 152 can select an object using known techniques, such as selecting an object that exists in a position in virtual space that overlaps with the hand that is the indicator detected by the detection unit 151, or selecting an object that collides with a ray that extends from the hand that is the indicator in virtual space according to predetermined conditions. The selection unit 152 may select an object when the hand detected by the detection unit 151 performs a predetermined action.

Furthermore, if the objects selected by the above process satisfy predetermined conditions, the selection unit 152 determines that multiple objects are selection candidates. For example, if a predetermined condition is satisfied, such as when multiple objects overlap at the position pointed to by the indicator or when another object exists near the object selected by the indicator, the selection unit 152 determines that multiple objects according to the condition are selection candidates. In other words, if it is expected that an incorrect object may be selected based on the display status of the objects, the selection unit 152 determines that multiple objects according to the condition are selection candidates. On the other hand, if the above conditions are not satisfied, the selection unit 152 determines that there is only one selection candidate object. If there is only one selection candidate object, the selection unit 152 determines that object as the object to be selected.

When the selection unit 152 selects multiple objects as selection candidates, the angle setting unit 153 assigns an angle to each of the selection candidate objects, thereby setting an angle range corresponding to each object. The angle setting unit 153 then stores the setting results in the storage unit 140 as set angle information 142.

For example, the angle setting unit 153 uniformly assigns angles within a predetermined range to each object selected as a selection candidate by the selection unit 152. For example, if the number of objects selected as selection candidates by the selection unit 152 is four, the angle setting unit 153 assigns 45 degrees to each of the four objects, as shown in FIG. 3. For example, in the case of FIG. 3, the angle setting unit 153 assigns spherical objects to angles between 0 degrees and less than 45 degrees, and rectangular parallelepiped objects to angles between 45 degrees and less than 90 degrees. Furthermore, the angle setting unit 153 assigns conical objects to angles between 90 degrees and less than 135 degrees, and star-shaped objects to angles between 135 degrees and less than 180 degrees.

The range of angles assigned by the angle setting unit 153 may be other than 0 to 180 degrees. For example, the angle setting unit 153 may assign angles in the range of 0 to 90 degrees, or 0 to 360 degrees. The angle setting unit 153 may also assign a range such as -90 to 90 degrees. The range of angles assigned by the angle setting unit 153 may vary depending on, for example, the number of objects selected by the selection unit 152 as selection targets. For example, the angle setting unit 153 may be configured to assign a wider range of angles as the number of objects selected by the selection unit 152 as selection targets increases. The angle assignment by the angle setting unit 153 does not necessarily have to be uniform for each object.

The angle calculation unit 154 acquires the angle of the hand that is the indicator by calculating the angle of the hand that is the indicator detected by the detection unit 151 based on the shape and tilt of the hand detected by the detection unit 110. In other words, the angle calculation unit 154 calculates the angle of the hand that is the indicator based on the results of detection by the detection unit 110 and the results of detection by the detection unit 141 (for example, data acquired by a camera, sensor, etc.).

For example, the angle calculation unit 154 calculates the angle of the hand based on a state in which the palm is facing up and parallel to a reference plane such as the ground. For example, as shown in FIG. 4, the angle calculation unit 154 calculates 0 degrees when the palm is facing up and parallel to the ground. The angle calculation unit 154 also calculates the angle of the palm (or a plane parallel to it) with respect to the reference plane as the hand angle. For example, in the case of FIG. 5, the angle calculation unit 154 calculates that the hand angle is 80 degrees. The angle calculation unit 154 also calculates 180 degrees when the palm is facing down and parallel to the ground. For example, in this way, the angle calculation unit 154 calculates the angle corresponding to the adduction or abduction of the hand according to the rotation of the arm around the axis along the length of the arm as the hand angle.

The angle calculation unit 154 may use known means to determine the shape and tilt of the hand.

The determination unit 155 determines an object to select from among the candidate objects based on the set angle information 142 and the result of the calculation by the angle calculation unit 154.

For example, the determination unit 155 checks to which object the angle calculated by the angle calculation unit 154 is assigned in the set angle information 142. Then, the determination unit 155 determines the object to which the angle calculated by the angle calculation unit 154 is assigned in the set angle information 142 as the object to be selected.

For example, Figure 6 illustrates a case where the angle calculation unit 154 calculates 0 degrees. In this case, the calculation result by the angle calculation unit 154 falls within the range of 0 degrees or more and less than 45 degrees. Therefore, the determination unit 155 determines a spherical object that corresponds to the above range as the object to be selected.

For example, Figure 7 illustrates a case where the angle calculation unit 154 calculates 80 degrees. In this case, the calculation result by the angle calculation unit 154 falls within the range of 45 degrees or more and less than 90 degrees. Therefore, the determination unit 155 determines the rectangular parallelepiped object corresponding to the above range as the object to be selected.

For example, as described above, the determination unit 155 determines, in the setting process by the angle setting unit 153, the object to be selected is the object to which the angle calculated by the angle calculation unit 154 is assigned.

The display unit 156 displays objects based on the object information 141. That is, the display unit 156 displays an object of the shape indicated by the object information 141 at the position indicated by the object information 141. The display unit 156 can also display an object according to the result of the determination by the determination unit 155. For example, the display unit 156 can display only the object determined by the determination unit 155 from among the objects that have become selection candidates. In this case, the display unit 156 may not display the objects that have become selection candidates other than the object determined by the determination unit 155, or may display them transparently, for example.

For example, Figure 8 shows an example of a display by the display unit 156 when the angle calculation unit 154 calculates 0 degrees. In this case, as described above, the determination unit 155 determines, for example, a spherical object as the object to be selected. Therefore, the display unit 156 displays a spherical object.

The above is an example configuration of the display device 100. Next, an example operation of the display device 100 will be described with reference to Figure 9.

Figure 9 shows an example of the operation of the display device 100. Referring to Figure 9, the selection unit 152 selects an object displayed in the virtual space using the results of detection by the detection unit 151 (step S101).

The selection unit 152 also checks whether the selected object satisfies predetermined conditions (step S102). If the selected object does not satisfy the predetermined conditions (step S102, No), the selection unit 152 determines the selected object as the object to be selected. On the other hand, if the selected object satisfies the predetermined conditions (step S102, Yes), the selection unit 152 determines that multiple objects that satisfy the predetermined conditions are selection candidates.

When multiple objects are selected as selection candidates, the angle setting unit 153 assigns an angle to each selection candidate object, thereby setting an angle range for each object (step S103). The angle calculation unit 154 calculates the angle of the hand, which is the indicator detected by the detection unit 151, based on the shape and tilt of the hand detected by the detection unit 110 (step S104). The determination unit 155 then determines the object to select from the selection candidate objects based on the result set by the angle setting unit 153 and the result of calculation by the angle calculation unit 154 (step S105).

The display unit 156 displays an image according to the result of the determination made by the determination unit 155 (step S106). For example, the display unit 156 displays only the object determined by the determination unit 155 from among the multiple objects that are candidates for selection.

In this way, the display device 100 has an angle setting unit 153, an angle calculation unit 154, and a determination unit 155. With this configuration, the determination unit 155 can determine an object to select from among the candidate objects based on the result set by the angle setting unit 153 and the result of calculation by the angle calculation unit 154. This makes it possible to accurately select an object even when it is difficult to accurately select an object, for example, when there are overlapping objects.

In this embodiment, the example is given where the storage unit 140 has object information 141. However, the object information 141 may be stored in an external storage device. In other words, the display device 100 may be configured to perform display based on the object information 141 acquired via the communication I/F unit 130.

Furthermore, in this embodiment, an example has been given in which a hand is detected as the indicator. However, the indicator may be something other than a hand. For example, the indicator may be a device such as a controller, or a human body part other than a hand, such as an eye, head, or upper arm. For example, when a human body part other than a hand is used as the indicator, the angle setting unit 153 can assign the direction of the viewpoint, the angle of rotation around the elbow, the tilt or angle of the head, etc. to objects that are candidates for selection. Furthermore, when a device such as a controller is used as the indicator, the angle calculation unit 154 may calculate the angle of the indicator based on data acquired by a sensor such as a magnetic sensor, acceleration sensor, or gyro sensor included in the device such as the controller.

Furthermore, in this embodiment, an example has been given in which the indicator used by the selection unit 152 when making a selection and the indicator for which the angle calculation unit 154 calculates the angle (i.e., the indicator used when selecting an object from among the selection candidate objects) are the same. However, the indicator used by the selection unit 152 when making a selection and the indicator for which the angle calculation unit 154 calculates the angle may be different. For example, the display device 100 may select an object in accordance with the controller, which is the indicator, and then determine the object to select from among the selection candidate objects in accordance with the results of eye tracking. In this way, the display device 100 may include multiple indicators.

In addition, in this embodiment, a case has been described in which the angle calculation unit 154 calculates the angle of the hand based on data acquired by a camera, sensor, or the like included in the detection unit 110. However, the display device 100 may acquire information indicating the angle of a pointer such as a hand by, for example, accepting input of information indicating the angle of the pointer from a user. In other words, the angle of the pointer may be physically measured or may be subjectively estimated by the user. When accepting input of information indicating the angle of the pointer from a user, the display device 100 does not need to include the angle calculation unit 154.

Second Embodiment
Next, a second embodiment of the present disclosure will be described with reference to Fig. 10 and Fig. 11. In the second embodiment of the present disclosure, an overview of the configuration of a selection device 200 that is an information processing device will be described.

Fig. 10 shows an example of the hardware configuration of the selection device 200. Referring to Fig. 10, the selection device 200 has, as an example, the following hardware configuration.
・CPU (Central Processing Unit) 201 (arithmetic unit)
ROM (Read Only Memory) 202 (storage device)
RAM (Random Access Memory) 203 (storage device)
Program group 204 loaded into RAM 203
A storage device 205 that stores the program group 204
A drive device 206 that reads and writes data from and to a recording medium 210 outside the information processing device
A communication interface 207 that connects to a communication network 211 outside the information processing device
Input/output interface 208 for inputting and outputting data
A bus 209 that connects each component

The selection device 200 can realize the functions of the setting unit 221, acquisition unit 222, and determination unit 223 shown in FIG. 11 by having the CPU 201 acquire and execute the program group 204. The program group 204 is stored in advance in, for example, the storage device 205 or ROM 202, and is loaded into the RAM 203 or the like by the CPU 201 for execution as needed. The program group 204 may be supplied to the CPU 201 via the communication network 211, or may be stored in advance on the recording medium 210, with the drive device 206 reading out the programs and supplying them to the CPU 201.

Note that Figure 10 shows an example hardware configuration of the selection device 200. The hardware configuration of the selection device 200 is not limited to the above-described case. For example, the selection device 200 may be configured with only a portion of the above-described configuration, such as excluding the drive device 206.

The setting unit 221 sets the corresponding angle range for each of the multiple objects that become selection candidates as a result of a predetermined selection process.

The acquisition unit 222 acquires the angle of the pointer used when selecting an object from among the selection candidate objects.

The determination unit 223 determines the object to select based on the results of the setting by the setting unit 221 and the results of the acquisition by the acquisition unit 222.

As such, the selection device 200 has a setting unit 221, an acquisition unit 222, and a determination unit 223. With this configuration, the determination unit 223 can determine the object to select based on the results of the setting by the setting unit 221 and the results of acquisition by the acquisition unit 222. This makes it possible to accurately select an object even when it is difficult to do so.

Note that an information processing device such as the selection device 200 described above can be realized by incorporating a predetermined program into the information processing device. Specifically, another form of the program of the present invention is a program for implementing processing in an information processing device: setting a corresponding angle range for each of a plurality of objects that become selection candidates as a result of a predetermined selection process; acquiring the angle of the indicator used when selecting an object from the selection candidate objects; and determining the object to select based on the setting result and the acquired result.

The selection method executed by the information processing device described above involves the information processing device setting a corresponding angle range for each of a plurality of objects that become selection candidates as a result of a predetermined selection process, acquiring the angle of the indicator used when selecting an object from the selection candidate objects, and determining the object to select based on the setting result and the acquired result.

Inventions such as a program (or recording medium) or selection method having the above-described configuration have the same functions and effects as those described above, and can therefore achieve the above-described objectives of the present invention.
