Touchscreens are the most successful input method for smartphones. Despite their flexibility,
touch input is limited to the location of taps and gestures. We present PalmTouch, an …

Ubiquitous computing requires robust and sustainable sensing techniques to detect users
for explicit and implicit inputs. Existing solutions with cameras can be privacy-invasive …

We present a new type of augmented mechanical keyboard, capable of sensing rich and
expressive motion gestures performed both on and directly above the device. Our hardware …

Tablet computers are often called upon to emulate classical pen-and-paper input. However,
touchscreens typically lack the means to distinguish between legitimate stylus and finger …

Many finger sensing input devices now support proximity input, enabling users to perform in-
air gestures. While near-surface interactions increase the input vocabulary, they lack tactile …

This paper presents RFTouchPads, a system of batteryless and wireless modular hardware
designs of two-dimensional (2D) touch sensor pads based on the ultra-high frequency …

We explored new interaction scenarios that can be realized when a touchpad outputs fast
and high-resolution spatio-temporal tactile patterns to the touch-sensitive skin on the …

We investigate performance characteristics when switching between four pointing methods:
absolute touch, absolute pen, relative mouse, and relative trackpad. The established …

We present FlickBoard, which combines a touchpad and a keyboard into the same
interaction area to reduce hand movement between a separate keyboard and touchpad. Our …

We demonstrate a method for stimulating the fingertip with touchable electric arcs above a
hover sensing input device. We built a hardware platform using a high-voltage resonant …
