Detailed Description

The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.

Example one

In order to provide a natural user gesture, and enable an electronic device to recognize the gesture and execute a corresponding control instruction, an embodiment of the present invention provides an information processing method, where the method is applied to an electronic device, the electronic device includes a sensing unit, and as shown in fig. 1, the method includes:

step 101, obtaining a first sensing point set at a first time by a sensing unit, wherein the input gesture starts when the first sensing point set is obtained at the first time by the sensing unit.

The first sensing point set is a set formed by sensing points in an area covered by the gesture of the user at the first moment. The first moment is the moment when the user starts inputting the gesture, and is also the moment when the electronic equipment senses the gesture input by the user. When the electronic equipment senses the gesture input by the user, a first moment is determined, the sensing points in the area covered by the gesture of the user are obtained at the first moment through the sensing unit, and a first sensing point set is formed by the sensing points.

And 102, extracting three first induction points from the first induction point set according to a preset rule.

In the embodiment of the invention, a gesture that the palm of the user is placed on the screen of the electronic device and the thumb of the user is close to or far away from the index finger is recognized, as shown in fig. 2. Therefore, the embodiment of the present invention first recognizes the gesture of the palm, and there are various ways to recognize the gesture of the palm, one way is: and performing similarity calculation on the shape formed by the area covered by the user gesture and a preset palm shape, if the calculated similarity value is greater than or equal to a preset similarity threshold value, identifying the shape as the palm gesture, and otherwise identifying the shape as a non-palm gesture. In the case where the non-palm gesture is recognized, the information processing method subsequent to the embodiment of the present invention is not performed.

After the palm gesture is recognized, the electronic device needs to extract three first sensing points from the sensing points in the area covered by the palm gesture of the user according to a preset rule, where the three first sensing points include a first sub-first sensing point (shown as sensing point a in fig. 2), a second sub-first sensing point (shown as sensing point B in fig. 2), and a third sub-first sensing point (shown as sensing point C in fig. 2). The preset rule for extracting the first sensing point can be set according to actual needs, for example:

one preset rule may be: the method comprises the steps that the area covered by the gesture of a user is compared with a preset palm shape, a line segment of a thumb (a first line segment for short) and a line segment of a forefinger (a second line segment for short) are determined, the preset palm shape can be various, and the first line segment and the second line segment can be comprehensively determined through comparison with various shapes; the induction point at the top end of the first line segment is selected as a second sub first induction point, the induction point at the top end of the second line segment is selected as a third sub first induction point, and the intersection point of the extension line of the first line segment or the first line segment and the extension line of the second line segment or the second line segment is selected as a first sub first induction point.

Another preset rule may be: the method comprises the steps that the area covered by the gesture of a user is compared with a preset palm shape, a line segment of a thumb (a first line segment for short) and a line segment of a forefinger (a second line segment for short) are determined, the preset palm shape can be various, and the first line segment and the second line segment can be comprehensively determined through comparison with various shapes; selecting the sensing point at the top end of the first line segment as a second sub first sensing point, selecting the sensing point at the top end of the second line segment as a third sub first sensing point, calculating the geometric center point of the area covered by the user gesture, and selecting the sensing point at the geometric center point as a first sub first sensing point.

The preset rules in the embodiments of the present invention are not limited to the above examples.

And 103, acquiring a second sensing point set at a second moment through the sensing unit.

The second sensing point set is a set formed by sensing points in an area covered by the user gesture at the second moment. The electronic equipment obtains the induction points in the area covered by the user gesture at the second moment through the induction unit, and the induction points form a second induction point set.

And 104, extracting three second induction points from the second induction point set according to a preset rule.

The electronic device needs to extract three second sensing points including a first sub-second sensing point, a second sub-second sensing point and a third sub-second sensing point from the sensing points in the area covered by the user palm gesture at the second moment according to a preset rule. The preset rule for extracting the second sensing point can be set according to actual needs, for example:

one preset rule may be: the method comprises the steps that the area covered by the gesture of a user is compared with a preset palm shape, a line segment of a thumb (a first line segment for short) and a line segment of a forefinger (a second line segment for short) are determined, the preset palm shape can be various, and the first line segment and the second line segment can be comprehensively determined through comparison with various shapes; the induction point at the top end of the first line segment is selected as a second sub-second induction point, the induction point at the top end of the second line segment is selected as a third sub-second induction point, and the intersection point of the extension line of the first line segment or the first line segment and the extension line of the second line segment or the second line segment is selected as a first sub-second induction point.

Another preset rule may be: the method comprises the steps that the area covered by the gesture of a user is compared with a preset palm shape, a line segment of a thumb (a first line segment for short) and a line segment of a forefinger (a second line segment for short) are determined, the preset palm shape can be various, and the first line segment and the second line segment can be comprehensively determined through comparison with various shapes; selecting the sensing point at the top end of the first line segment as a second sub-second sensing point, selecting the sensing point at the top end of the second line segment as a third sub-second sensing point, calculating the geometric center point of the area covered by the user gesture, and selecting the sensing point positioned at the geometric center point as a first sub-second sensing point.

The preset rules in the embodiments of the present invention are not limited to the above examples. However, the predetermined rule used for extracting three first sensing points from the first sensing point set and the predetermined rule used for extracting three second sensing points from the second sensing point set must be the same to ensure the accuracy of the calculation result.

And 105, processing the three first sensing points and the three second sensing points to generate a processing result.

Specifically, the position coordinates of three first induction points at a first moment and the position coordinates of three second induction points at a second moment are respectively recorded;

the processing result is composed of a first comparison result and a second comparison result.

And 106, when the processing result shows that the first distance between the first sub first sensing point at the first moment and the first sub second sensing point at the second moment is smaller than the preset threshold value and the second distance between the second sub first sensing point at the first moment and the third sub first sensing point at the first moment is changed relative to the third distance between the second sub second sensing point at the second moment and the third sub second sensing point at the second moment, generating a control command according to the change trend of the second distance and the first distance.

And when the first comparison result shows that the first distance between the first sub first sensing point at the first moment and the first sub second sensing point at the second moment is smaller than the preset threshold value, and the second comparison result shows that the second distance between the second sub first sensing point at the first moment and the third sub first sensing point is changed relative to the third distance between the second sub second sensing point at the second moment and the third sub second sensing point, generating a control command according to the change trend of the second distance and the first distance.

Specifically, when the first distance is smaller than a predetermined threshold and the second distance is larger than the third distance, the electronic device generates a first control instruction;

when the first distance is smaller than the preset threshold value and the second distance becomes smaller relative to the third distance, the electronic equipment generates a second control instruction.

Step 107, responding to the control instruction.

The responding control instruction means that the electronic equipment executes processing corresponding to the control instruction.

It should be noted that the control instruction of the embodiment of the present invention is used to instruct to change the page display effect, where the change of the page display effect includes, but is not limited to, at least one of the following: enlarging the page, reducing the page, curling the page and turning the page.

Specifically, when the control instruction is used for instructing to zoom out the page, when the first distance is smaller than the predetermined threshold and the second distance is larger than the third distance, the first control instruction generated by the electronic device is used for instructing to zoom out the page; and when the first distance is smaller than the preset threshold value and the second distance is smaller relative to the third distance, the electronic equipment generates a second control instruction for indicating the page to be enlarged.

When the control instruction is used for indicating page curling, the electronic equipment calculates the page curling amplitude through a preset conversion relation according to the change value of the second distance at the first moment relative to the third distance at the second moment; the control instruction is used for indicating the corresponding amplitude of the page curl. Specifically, the conversion relationship is required to satisfy that when the second distance at the first time is larger than the third distance at the second time, the amplitude of the calculated page curl is correspondingly larger, and when the second distance at the first time is smaller than the third distance at the second time, the amplitude of the calculated page curl is correspondingly smaller. When the input gesture is finished, generating a page turning instruction, and responding to the page turning instruction; the responding page turning instruction means that the electronic device executes a page turning operation, and an object of the page turning operation is an object covered by a user gesture, such as: pictures, documents, etc.

It is emphasized that the method of the embodiment of the present invention further comprises: the electronic equipment obtains an Nth sensing point set at the Nth moment through the sensing unit; n is a positive integer greater than or equal to 2, the Nth moment is the last moment when the input gesture is cancelled, and the input gesture is finished when the sensing unit obtains the Nth sensing point set at the Nth moment.

That is, the method of the embodiment of the present invention is not limited to include the first time and the second time before the nth time, and may include a third time, a fourth time, and even more up to the nth-1 time. Between the third time and the nth time, the electronic device still needs to obtain a corresponding sensing point set at each time, and extract three corresponding sensing points from the corresponding sensing point set according to the same predetermined rule; and processing the three sensing points at the next moment and the three sensing points at the previous moment to generate corresponding processing results, and similarly, when the processing results show that the first distance between the first sub-sensing point at the previous moment and the first sub-sensing point at the next moment is smaller than a preset threshold value, and the second distance between the second sub-sensing point at the previous moment and the third sub-sensing point is changed relative to the third distance between the second sub-sensing point at the next moment and the third sub-sensing point, generating a control command according to the change trend of the second distance and the first distance, and responding to the control command.
