[need help] Sensor choice for a kiss?

Hello guys,

I am working on a project concept which involves identifying user input in the form of a kiss - all I need is to correctly identify a kiss ( ideally on a flat surface ). I tried it on a multitouch device but it's less than optimal - the touch events from a kiss is pretty inconsistent, also I do want the input to be able to interact with a computer. So now I'm exploring the possibilities to do it with Arduino.

I don't have much experience with hardware, so I'm looking for advice here - is there a way to properly identify a kiss with Arduino? Or, what kind of sensor(s) would be the best solution to this?

Thanks in advance to any input,


If you kiss someone his/hers resistance chances ;)

Seriously, you could creat a sort of ohm meter to detect the resistance of the human body, it is lower than air. THere will be differences between the dry kiss, the lipstift kiss and the french kiss as different levels of moisture will chance the resistance ;)

Another option is that touching the surface does something capacitative as it gets connected to GND. On the playground there are a few articles: - http://www.arduino.cc/playground/Main/CapSense - http://www.arduino.cc/playground/Code/CapacitiveSensor

interested if this gonna work!
