Several generations of inexpensive depth cameras have opened the possibility for new
kinds of interaction on everyday surfaces. A number of research systems have demonstrated …

Accurately predicting the accuracy of finger-touch target acquisition is crucial for designing
touchscreen UI and for modeling complex and higher level touch interaction behaviors …

Some embodiments of the present invention include a method of differentiating touch screen
users based on characterization of features derived from the touch event acoustics and …

Expressiveness, which we define as the extent to which rich and complex intent can be
conveyed through action, is a vital aspect of many human interactions. For instance, paint on …

Users' individual differences in their mobile touch behaviour can help to continuously verify
identity and protect personal data. However, little is known about the influence of GUI …

The development of robust methods to identify which finger is causing each touch point,
called" finger identification," will open up a new input space where interaction designers can …

This book addresses the new interaction modalities that are becoming possible with new
devices by looking at user interfaces from an input perspective. It deals with modern input …

An apparatus classifies touch events. The apparatus includes a touch sensitive surface
configured to generate a touch event when an object touches the touch sensitive surface …

Camera-based interfaces in mobile devices are starting to be used in games and apps, but
few works have evaluated them in terms of usability or user perception. Due to the changing …

Many technologies exist that have the ability to digitize different types of input. There are two
main touch sensing approaches: active and passive. Passive devices include those that are …
