FTIR - Identifying users via Biometrics?
It just occurred to me that it might be possible to identify individual users (and specific fingers) in a multiuser setting via their finger prints. You could acquire a high resolution picture whenever a new touch is detected and compare the fingerprint pattern to a database just like current biometric securty devices currently work. The only problem is that it might not be fast enough for realtime but it is an interesting idea.. Most fingerprint scanners you find on laptops are made using FTIR.

I had the same idea. But somebody told me you would need a very high res camera, so maybe something for the future, since we dont have alot of budget. Maybe something with face recognition instead? In case somebody cuts off all your fingers. A head is alot more difficult to remove :)
It would take a high res camera, but maybe you could use a photo camera - high mega pixel cameras are getting cheaper all the time.
Being able to tag fingers is more useful I think - you could assign a different gesture to a thumb or an index finger that way.
True they are getting cheaper.
What kind of resolution were you thinking about?
You could also do a combo of recognition. That a person with the 10 fingerprints and with a familiar face has only acces to the system.
Different gestures per finger is a good idea indeed.
