Device-free gesture tracking is an enabling HCI mechanism for small wearable devices
because fingers are too big to control the GUI elements on such small screens, and it is also …

We present WiGest: a system that leverages changes in WiFi signal strength to sense in-air
hand gestures around the user's mobile device. Compared to related work, WiGest is unique …

We present fingerIO, a novel fine-grained finger tracking solution for around-device
interaction. FingerIO does not require instrumenting the finger with sensors and works even …

Recent work has shown that inaudible signals (at ultrasound frequencies) can be designed
in a way that they become audible to microphones. Designed well, this can empower an …

Video games, Virtual Reality (VR), Augmented Reality (AR), and Smart appliances (eg,
smart TVs) all call for a new way for users to interact and control them. This paper develops …

Next generation devices, such as virtual reality (VR), augmented reality (AR), and smart
appliances, demand a simple and intuitive way for users to interact with them. To address …

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 …

A mouse has been one of the most successful user interfaces due to its intuitive use. As
more devices are equipped with displays and offer rich options for users to choose from, a …
