Enabling touch gesture sensing on all surfaces of the mobile device, not limited to the
touchscreen area, leads to new user interaction experiences. In this paper, we propose …

ForcePhone is a novel system that enables commodity phones to recognize the force
applied to their touch screen and body. Researchers have shown the usefulness and …

Today's wearable and mobile devices typically use separate hardware components for
sensing and actuation. In this work, we introduce new opportunities for the Linear Resonant …

Active Edge is a feature of Google Pixel 2 smartphone devices that creates a force-sensitive
interaction surface along their sides, allowing users to perform gestures by holding 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 …

Wearable vibrotactile devices have many potential applications, including sensory
substitution for accessibility and notifications. Currently, vibrotactile experimentation is done …

Side channels are unintended pathways within target systems that leak internal target
information. Side-channel sensing (SCS) is the process of exploiting side channels to extract …

Technical advances in the smart device market have fixated smartphones at the heart of our
lives, warranting an ever more secure means of authentication. Although most smartphones …

Devices can be made more intelligent if they have the ability to sense their surroundings and
physical configuration. However, adding extra, special purpose sensors increases size …

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 …
