Current touch devices, such as capacitive touchscreens are based on the implicit
assumption that users acquire targets with the center of the contact area between finger and …

It is generally assumed that touch input cannot be accurate because of the fat finger
problem, ie, the softness of the fingertip combined with the occlusion of the target by the …

We can touch things, and our senses tell us when our hands are touching something. But
most computer input devices cannot detect when the user touches or releases the device or …

As mobile and tangible devices are getting smaller and smaller it is desirable to extend the
interaction area to their whole surface area. The HandSense prototype employs capacitive …

Interacting with mobile devices using touch can lead to fingers occluding valuable screen
real estate. For the smallest devices, the idea of using a touch-enabled display is almost …

We present a predictive model for the functional area of the thumb on a touchscreen surface:
the area of the interface reachable by the thumb of the hand that is holding the device. We …

ABSTRACT A robotic system for object recognition is described that uses both active
exploratory tactile sensing and passive stereo vision. The complementary nature of these …

We present TapSense, an enhancement to touch interaction that allows conventional
surfaces to identify the type of object being used for input. This is achieved by segmenting …

In this paper, we explore how to add pointing input capabilities to very small screen devices.
On first sight, touchscreens seem to allow for particular compactness, because they integrate …
