Project Idea
One or more microphones on underside of device 1) Localize taps around the device on an ad hoc surface 2) Listen and classify gestures being performed (non-spatial) Some combination of the two above Possible uses: Laptop, smartphone, kitchen, light switch Reach goal: couple with projector for interactive graphics
Oblique from smartphone From lid of laptop

Project Idea
1.Skinput++ Entirely passive approach; better signal processing and machine learning 2.High resolution Skinput on the wrist (perhaps using accelerometers on wrist bone assembly) 3.1D (along arm) time of flight. 4.Add active elements to the skin, look at e.g., reflected signal, attenuation of particular frequencies. 5.Phase offset (receiver/transmitter pair on upper arm/wrist)

Warning!
Not for the feignt of heart! These projects need research, not just engineering Self motivated team I can advise project, but will be traveling a lot Expected end result is a publication

Project Idea
Large corpus of phone calls Mine calls for acoustic features See if personal closeness of the two individuals can be predicted Example app: bootstrapping sharing/privacy settings on social networking sites
