BOSI - Bluetooth Opensource Switch Interface

This is a chassis design of the Bluetooth switch interface for people with difficulty using a keyboard, mouse, or touchscreen on the mobile devices. People with disabilities press the button to select key on the on-screen keyboard or control the mouse cursor on the computer or mobile device. This switch interface design includes two versions: one button and two buttons. The buttons can be mounted on the table or on the wheelchair headrest or armrest. The texture on the button top helps people with vision impairments recognize the button functions. For example, the square on the one-button version can be set as the "Home" button for iOS.
