FaceSwitch - switch access 4‏+

This app recognizes face movements using face tracking technology and control external switch devices connected via Bluetooth. This app supports eight different facial movements: "Open Mouth," "Close Mouth," "Turn Face Right," "Turn Face Left," "Turn Face Up," "Turn Face Down," "Open Eyes," and "Close Eyes." It recognizes these facial movements and displays frames or lines on the recognized facial parts. Depending on the degree of the facial movements, red squares representing the amount of movement for each part move right and left along the sliders on the screen. When these red squares cross the position of the threshold on each slider, a switch signal is output. This app can use either the front or back camera and recognize facial movements even when the camera is placed at a certain distance from the user. For the switch output, either the battery-operated switch "MaBeee" or "Relay" (Switch Science ISP1507 Bluetooth-Relay Board) for Bluetooth connection can be chosen, enabling control of devices powered by batteries or those that accept switch input.

For more information on how to connect to "MaBeee" and "Relay", please watch the video on the following website.
