Description

Brainwave Assisted Rehabilitation System

The present invention relates to a rehabilitation system, and more particularly to a brain wave assisted rehabilitation system.

For patients with memory impairment, existing rehabilitation systems (such as memory rehabilitation systems) usually allow patients to watch a large number of multimedia files related to themselves, and hope to stimulate the patient's memory function through the above multimedia files. However, existing rehabilitation systems are usually unable to systematically screen multimedia files that can stimulate the patient's memory function, resulting in a lack of direction and efficiency in the rehabilitation process, and thus unable to effectively rehabilitate the patient's memory function.

Therefore, the inventors of the present invention believe that the above defects can be improved, and have conducted intensive research and applied scientific principles to finally propose the present invention which has a reasonable design and effectively improves the above defects.

The present invention provides a brain wave assisted rehabilitation system that can effectively rehabilitate the memory function of patients.

The present invention discloses a brain wave assisted rehabilitation system, which includes: a database, including a plurality of multimedia files with different characteristics; a playback module, electrically connected to the database, the playback module can load the plurality of multimedia files in the database to execute a playback task, and the playback module sequentially provides a user with the plurality of multimedia files to watch; a brain wave sensing unit, electrically connected to the playback module and the database, respectively, the brain wave sensing unit can analyze a brain wave signal when the user watches any of the multimedia files, and the brain wave sensing unit can detect the brain wave signal when the brain wave signal is not within a stimulation interval. an invalid tag is created for the corresponding multimedia file; a screening unit is electrically connected to the brain wave sensing unit and the database, the screening unit deletes the multimedia file with the invalid tag from the database so that the database is corrected, and the screening unit issues a valid playback instruction after the playback module completes the playback task; a control unit is electrically connected to the screening unit and the playback module, after the control unit receives the valid playback instruction, the control unit controls the playback module to reload the plurality of multimedia files in the database and re-execute the playback task.

In summary, the brain wave assisted rehabilitation system disclosed in the embodiment of the present invention can establish the invalid label for the corresponding multimedia file when the brain wave sensing unit analyzes that the brain wave signal is not within the stimulation interval, and then delete the multimedia file with the invalid label from the database through the screening unit to correct the database. When the playback module executes the playback task again through the control module, it can only load the database corrected by the screening unit (that is, the multimedia file with the invalid label has been deleted), so that the playback module can continuously provide the multimedia file that can stimulate the user's memory function, thereby effectively rehabilitating the user's memory function.

Please refer to FIG. 1 and FIG. 2 , the present embodiment discloses a brain wave assisted rehabilitation system 100. The brain wave assisted rehabilitation system 100 includes a database 1, a playback module 2 electrically connected to the database 1, a brain wave sensing unit 3 electrically connected to the playback module 2 and the database 1, a screening unit 4 electrically connected to the brain wave sensing unit 3 and the database 1, a control unit 5 electrically connected to the screening unit 4 and the playback module 2, and a personal audio and video database 6 electrically connected to the screening unit 4. It should be noted that the personal audio and video database 6 in the brain wave assisted rehabilitation system 100 can be selectively added according to design requirements, and the present invention is not limited thereto. Specifically, the personal video database 6 includes a personal multimedia file 61 of a user P (eg, a patient).

The database 1 includes a plurality of multimedia files 11 with different characteristics, and the plurality of multimedia files 11 in the database 1 are obtained arbitrarily by a public browser W in this embodiment, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the plurality of multimedia files 11 in the database 1 can also be obtained from the personal video database 6.

Furthermore, the plurality of multimedia files 11 with different characteristics in this embodiment may include music videos, animal videos (such as dogs and cats), historical videos, and entertainment clips (such as movie clips), etc., and the present invention is not limited thereto.

As shown in FIG1 , the playback module 2 can load a plurality of the multimedia files 11 in the database 1 to perform a playback task, and the playback module 2 (e.g., an electronic product) sequentially provides the user P with the plurality of the multimedia files 11. In other words, the playback module 2 only allows the user P to view one of the multimedia files 11 in each time period.

It should be noted that the brain wave sensing unit 3 can determine whether the user P has a reaction when viewing any of the multimedia files 11 by analyzing whether a brain wave signal when the user P views any of the multimedia files 11 is within a stimulation range, and determine whether one of the multimedia files 11 played by the playback module 2 can effectively evoke the relevant memory of the user P. In other words, the brain wave sensing unit 3 can be used to determine whether each of the multimedia files 11 can achieve a rehabilitation effect (or stimulation effect) on the memory function of the user P.

Furthermore, the brain wave signals include theta waves between 4 Hz and 8 Hz, alpha waves between 9 Hz and 12 Hz, beta waves between 13 Hz and 24 Hz, and gamma waves above 25 Hz, and the stimulation interval is between 4 Hz and 8 Hz or between 30 Hz and 100 Hz.

In order to facilitate understanding of this embodiment, the components of the brain wave sensing unit 3 and their matching relationships will be first described below, and the matching relationships between the brain wave sensing unit 3 and the database 1 and the playback module 2 will be described as appropriate.

As shown in FIG1 , the brain wave sensing unit 3 in this embodiment includes a bracket 31, a plurality of patches 32 connected to the bracket 31, an operation unit 33 electrically connected to the plurality of patches 32, and a feature recognition module 34 electrically connected to the operation unit 33. The bracket 31 (such as a helmet) is used to be worn on the head of the user P, and the plurality of patches 32 can be used to be attached to the head of the user P.

Furthermore, the brain wave sensing unit 3 can transmit the brain wave signal of the user P to the calculation unit 33 through the plurality of patches 32, and then the calculation unit 33 analyzes whether the brain wave signal is within the stimulation interval, so as to determine whether one of the multimedia files 11 played by the playback module 2 can achieve a memory rehabilitation effect (or stimulation effect) on the user P.

Furthermore, the brain wave sensing unit 3 is electrically connected to the playback module 2 and the database 1 through the feature recognition module 34. Specifically, when the brain wave sensing unit 3 analyzes that the brain wave signal of the user P viewing any of the multimedia files 11 is not within the stimulation interval, the brain wave sensing unit 3 can create an invalid tag for the corresponding multimedia file 11 through the feature recognition module 34.

Furthermore, when the brain wave sensing unit 3 analyzes that the brain wave signal of the user P when viewing any of the multimedia files 11 is not within the stimulation interval, it means that the user P has not reacted to the corresponding multimedia file 11, and thus it can be determined that one of the multimedia files 11 played by the playback module 2 cannot produce a rehabilitation effect (or stimulation effect) on the memory function of the user P. In other words, the feature recognition module 34 creates the invalid tag for the multimedia file 11 that cannot stimulate the memory function of the user P.

On the contrary, when the brain wave sensing unit 3 analyzes that the brain wave signal of the user P when viewing any of the multimedia files 11 is within the stimulation zone, it indicates that the user P can respond to the corresponding multimedia file 11, thereby being able to determine that one of the multimedia files 11 played by the playback module 2 can evoke the relevant memory of the user P to produce a memory function rehabilitation effect (i.e., can stimulate the memory function of the user P).

Furthermore, when the brain wave sensing unit 3 analyzes that the brain wave signal is within the stimulation interval, the feature recognition module 34 can further analyze one of the multimedia files 11 played by the playback module 2 to generate a multimedia analysis report 341. In more detail, the multimedia analysis report 341 includes the audio-visual features of one of the multimedia files 11.

It should be further explained that the brain wave assisted rehabilitation system 100 in this embodiment further includes an analysis unit A electrically connected to the plurality of patches 32. The analysis unit A can convert the brain wave signals to generate brain wave analysis data (such as an electroencephalogram (EEG)), but it can be selectively added according to design requirements, and the present invention is not limited thereto.

Accordingly, the brain wave assisted rehabilitation system 100 can verify again through the brain wave analysis data whether the brain wave signal analyzed by the calculation unit 33 in the brain wave sensing unit 3 is within the stimulation interval, and then can correct whether the feature recognition module 34 correctly establishes the invalid label for one of the corresponding multimedia files 11.

The above is a description of the components and their matching in the brain wave sensing unit 3 in this embodiment. The following will sequentially describe other components included in the brain wave assisted rehabilitation system 100 and explain the matching relationship between them and the brain wave sensing unit 3 when appropriate.

As shown in FIG. 1 and FIG. 2 , the brain wave sensing unit 3 is electrically connected to the screening unit 4 through the feature recognition module 34. Further, after the feature recognition module 34 creates an invalid tag for the corresponding multimedia file 11, the screening unit 4 can be used to delete the multimedia file 11 with the invalid tag from the database 1 so that the database 1 is corrected (i.e., updated to the corrected database 1′). In other words, the corrected database 1′ no longer has the multimedia file 11 that cannot stimulate the memory function of the user P.

For example, when the database 1 has six multimedia files 11, and the feature recognition module 34 creates invalid tags for three of the multimedia files 11, the screening unit 4 can delete the three multimedia files 11 with the invalid tags from the database 1, so that the database 1 is corrected (i.e., updated to the corrected database 1'). In addition, the number of the multimedia files 11 can be adjusted and changed according to design requirements, and the present invention is not limited here.

It should be further explained that the screening unit 4 in this embodiment can further include a collecting unit 41, and the collecting unit 41 can collect the personal multimedia files 61 in the personal video database 6 through the multimedia analysis report 341 and import them into the database 1 to update it into a modified database 1'.

In other words, the collecting unit 41 collects the personal multimedia file 61 of the user P according to the audio-visual features of the multimedia file 11 that can stimulate the memory function of the user P. According to the above configuration, the modified database 1' further includes the personal multimedia file 61 that can produce a memory rehabilitation effect on the user P.

Furthermore, the screening unit 4 issues an effective play instruction 4a after the play module 2 completes the play task (i.e., after the play module 2 completes playing all the multimedia files 11 loaded into the database 1). Then, as shown in FIG2 , after the control unit 5 receives the effective play instruction 4a, the control unit 5 can control the play module 2 to reload the multiple multimedia files 11 and the personal multimedia file 61 of the modified database 1′, and make the play module 2 execute the play task again.

According to the above configuration, the brain wave assisted rehabilitation system 100 provided in this embodiment can systematically screen out the multimedia file 11 that can stimulate the memory function of the user P through the design and matching of the database 1, the playback module 2, the brain wave sensing unit 3, and the screening unit 4, and when the control unit 5 controls the playback module 2 to execute the playback task again, it can only provide the user P with the multimedia file 11 that can make him react, thereby effectively rehabilitating the memory function of the user P.

Furthermore, the personal multimedia files 61 collected by the feature recognition module 34 can further enable the modified database 1' to have more audiovisual contents that can stimulate the memory function of the user P, and through multiple cycles of operation of the above-mentioned database 1, playback module 2, brain wave sensing unit 3, screening unit 4, and control unit 5, it can also be further verified whether the personal multimedia files 61 collected by the collection unit 41 can indeed effectively produce a memory function rehabilitation effect on the user P, so that the brain wave assisted rehabilitation system 100 provided in this embodiment can more accurately rehabilitate the memory function of the user P.

In addition, the brain wave assisted rehabilitation system 100 in this embodiment can further selectively include a warning unit 7 electrically connected to the brain wave sensing unit 3. When the brain wave sensing unit 3 analyzes that the brain wave signal is within the stimulation interval, the warning unit 7 activates a light signal, but it can be selectively added according to design requirements, and the present invention is not limited thereto. Furthermore, the light signal can assist a medical staff member in recording which type of multimedia file 11 the user P reacts to.
