Tongue mouse: Cursor control with your mouth!

I wanted to test the idea of using the tongue to control a computer. The most obvious way would be to map x/y coordinates in a Windows-style UI with tongue movements constrained to a plane. This doesn't work terribly well, as even though the tongue has fine motor control, it's very difficult to smoothy achieve the 2D movements needed to operate a system that has been developed around a classic mouse. I think there is possible applications for swipe interfaces, carousel menus, yes/no input, etc.

That is a tremendously cool trial. I have always been interested in alternative computer input methods.

You may want to consider trying a "trackpoint" style mouse that was used on many IBM laptops. I suspect that this would provide finer control as the user would only have to modulate pressure in any direction.

Great potential interface for those with limited movement or wheelchair bound. Don't stop.

thats what i was thinking mark. disabled folks could really benefit here. if the surface being brushed with the tongue was oriented in the mouth in the same spacial plane as the screen in front of them and the pointer speed was turned down it would be more intuitive to use id bet.

I wouldn't say that it's impossible to use the concept insead of a conventional mouse. It may feel less intuitive at first, but really - is a conventional mouse intuitive? Or are we just used to it... ?

I use a wheelchair myself, and when I see people steering a powered wheelchair by chin or breath pressure - that takes a lot to get used to, too.
With this mouse, You already have 4 types of signals, breath pressure only gives you 2.
And most spinal chord injured who cannot steer by chin need a lung machine, too, so they have very limited control over breath pressure but may be able to use their tongue normally.

It may never become the universal control (starting with hygienic issues), but for people who need their hands free because they're dirty, paralyzed or needed to perform another action (propelling my chair, in my case), I find it very interesting.

I especially like the use of standard components and light instead of hardware buttons because it's a lot easier to seal in. I wouldn't want to have old spit sipping out all the time... ;)
