We present ScraTouch, an interaction technique using fingernails, as a new input modality
by leveraging capacitive touch sensing. Differentiating between fingertip and fingernail …

We propose a novel phone-case-shaped interface named TetraForce, which enables four
types of force input consisting of two force directions (ie, pressure force and shear force) and …

We present ShiftTouch, an attachment-type passive interface that provides multiple inputs for
capacitive touchscreens with minimal screen occlusion. ShiftTouch utilizes multiple linear …

Most touch-based input devices, such as touchscreens and touchpads, capture low-
resolution capacitive images when a finger touches the device's surface. These devices only …

A touch interface is an important technology used in many devices, including touch panels in
smartphones. Many touch panels only detect the contact position. If devices can detect shear …

Tap inputs on the back of smartphones provide a solution to the occlusion problem but come
with challenges such as reduced accuracy and constrained functionality. In this work, we …

The palmrest area of laptops has the potential as an additional input space, considering its
consistent palm contact during keyboard interaction. We propose Palmrest+, leveraging …

Touch surfaces are used as input interfaces for many devices such as smartphones, tablets,
and smartwatches. However, the flexibility of the input surface is low, and the possible input …

Devices, methods and systems for controlling an electronic device using force-based
gestures are described. Force data from one or more force sensors, representing a force …

With phones becoming more powerful and such an essential part of our lives, manufacturers
are creating new device forms and interactions to better support even more diverse …
