According to various exemplary embodiments, when the charging state of the HMD device 110 or the input device 115 is determined that it is difficult to conduct the tutorial or when the acquired biosignal and input data are determined that it is difficult to conduct the tutorial, the manager device 300 may transmit an instruction for displaying guidance information for recommending to stop the tutorial progress to the HMD device 110. The manager device 300 may stop the tutorial progress.
According to various exemplary embodiments, the manager device 300 may determine whether the biosignal received during the progress of the tutorial is analyzable. When it is determined that the biosignal is not analyzable, as illustrated in
Here, the interface screen 1700 may include a first graphic object 1710 instructing to check the wearing state of the HMD device 110 that the sensor module is installed and the wearing state of the separate sensor device, a second graphic object 1720 representing at least one sensing electrode acquiring an analyzable biosignal or a biosignal that is not analyzable, and a third graphic object representing guidance information for guiding the wearing of the HMD device 110 or the wearing of the separate sensor device. For example, the second graphic object 1720 may be an image for a bio module or a separate sensor device that represents a sensing electrode acquiring an analyzable biosignal, among at least one sensing electrode, with a first color (for example, blue) and represents a sensing electrode acquiring a non-analyzable biosignal with a second color (for example, yellow) different from the first color.
The interface screen 1700 may further include a fourth graphic object 1740 for conducting by ignoring the re-wearing of the HMD device or the separate sensor device.
The manager may support or monitor the progress of the tutorial of the user by means of the interface screen.
When the tutorial and the cognitive function test are completed, the manager device 300 may receive evaluation result data for the cognitive function of the user from the service providing server 130. The manager device 300 may display an interface screen 1800 representing the received evaluation result data as illustrated in
Referring to
According to various exemplary embodiments, the evaluation result data may be provided to the HMD device 110 and the manager device 300 or provided only to the manager device 300. According to various exemplary embodiments, the evaluation result data is provided to the HMD device 110 and the manager device 300 may display the mirrored screen.
The manager may provide a result for the cognitive function test to the user by means of the interface screen and may consult the cognitive function of the user based thereon.
According to the proposed exemplary embodiment, configurations of various interface screens related to the cognitive function test program and the graphic objects are not limited to the above description and the interface screens and graphic objects may be configured in various forms.
Even though according to the proposed exemplary embodiment, the interface screen related to the cognitive function test program has been described, the interface screen related to the cognitive function training program is also provided in a similar way as described above.
As described above, according to the present invention, the user may more easily and conveniently perform the cognitive function activity with the help of the manager and the manager helps or monitors the progress of the cognitive function activity of the user to provide higher professionalism and quality diagnostic results while reducing the time and resources required for the progress of the cognitive function activity.
The device and the method according to the exemplary embodiment of the present invention may be implemented as a program command which may be executed by various computers to be recorded in a computer readable medium. The computer readable medium may include solely a program command, a data file, and a data structure or a combination thereof.
The program commands recorded in the computer readable medium may be specifically designed or constructed for the present invention or those known to those skilled in the art of a computer software to be used. Examples of the computer readable recording medium include magnetic media such as a hard disk, a floppy disk, or a magnetic tape, optical media such as a CD-ROM or a DVD, magneto-optical media such as a floptical disk, and a hardware device which is specifically configured to store and execute the program command such as a ROM, a RAM, and a flash memory. Examples of the program command include not only a machine language code which is created by a compiler but also a high level language code which may be executed by a computer using an interpreter.
The above-described hardware device may operate as one or more software modules in order to perform the operation of the present invention and vice versa.
Although the exemplary embodiments of the present invention have been described in more detail with reference to the accompanying drawings, the present invention is not limited thereto and may be embodied in many different forms without departing from the technical concept of the present invention. Therefore, the exemplary embodiments of the present invention are provided for illustrative purposes only but not intended to limit the technical concept of the present invention. The scope of the technical concept of the present invention is not limited thereto. Therefore, it should be understood that the above-described exemplary embodiments are illustrative in all aspects and do not limit the present invention. The protective scope of the present invention should be construed based on the following claims, and all the technical concepts in the equivalent scope thereof should be construed as falling within the scope of the present invention.
