The expansion of touch-sensitive technologies, ranging from smartwatches to wall screens,
triggered a wider use of gesture-based user interfaces and encouraged researchers to …

We examine radar-based gesture input for interactive computer systems, a technology that
has recently grown in terms of commercial availability, affordability, and popularity among …

We studied the memorability of free-form gesture sets for invoking actions. We compared
three types of gesture sets: user-defined gesture sets, gesture sets designed by the authors …

Gestural interaction has evolved from a set of novel interaction techniques developed in
research labs, to a dominant interaction modality used by millions of users everyday …

We present Lip-Interact, an interaction technique that allows users to issue commands on
their smartphone through silent speech. Lip-Interact repurposes the front camera to capture …

Direct-touch interaction on mobile phones revolves around screens that compete for visual
attention with users' real-world tasks and activities. This paper investigates the impact of …

Microwave radars bring many benefits to mid-air gesture sensing due to their large field of
view and independence from environmental conditions, such as ambient light and …

Multi-touch gestures have become popular on a wide range of touchscreen devices, but the
programming of these gestures remains an art. It is time-consuming and error-prone for a …

Although menu selection has been extensively studied in HCI, most existing studies have
focused on sighted users, leaving blind users' menu selection under-studied. In this paper …

Menus are used for exploring and selecting commands in interactive applications. They are
widespread in current systems and used by a large variety of users. As a consequence, they …
