I am a mathematician – computer scientist working in Information Security. See my Resume [doc] [pdf].
In my free time I develop HW and SW for people with disabilities.
Disability projects
Mouth-operated Mouse
This section will contain the HW description and the controller SW for a USB device, which allows people to communicate with computers without using hands, by moving their head and blowing (sip/puff) into a mouthpiece, or apply lip-byte pressure.
The controller SW (in its first version for MS Windows XP+) will be distributed as shareware. It simulates joystick and mouse, allows typing text, selecting tasks from a table, and playing music.

The device was described in my US patent application #61185278 of Jun 9, 2009 but hereby I grant permission to anyone for using our inventions in making such and similar devices, if they are not made for profit. It means you can only ask for the actual fair price of commercially available parts built in. Derivative work (modification) is also allowed, if such a work is made public under similar conditions.
For permissions for manufacturing such devices or for derivative work for profit, please contact me.
More details are coming soon……
