Mid-air interaction is a distinct style of natural HCI (Human-Computer Interaction). In mid-air
interaction, users make use of their whole body—with a strong focus on hands—and apply …

In this review, we describe current Machine Learning approaches to hand gesture
recognition with depth data from time-of-flight sensors. In particular, we summarise the …

In this paper, we develop a vision-based system that employs a combined RGB and depth
descriptor to classify hand gestures. The method is studied for a human-machine interface …

We investigate how to reveal an initial mid-air gesture on interactive public displays. This
initial gesture can serve as gesture registration for advanced operations. We propose three …

When the user is engaged with a real-world task it can be inappropriate or difficult to use a
smartphone. To address this concern, we developed ShoeSense, a wearable system …

Most of today's public displays only show predefined contents that passers-by are not able to
change. We argue that interactive public displays would benefit from immediately usable …

Drones are becoming ubiquitous and offer support to people in various tasks, such as
photography, in increasingly interactive social contexts. We introduce drone. io, a projected …

We present an empirical comparison of eleven bare hand, mid-air mode-switching
techniques suitable for virtual reality in two experiments. The first evaluates seven …

We propose HeadCross, a head-based interaction method to select targets on VR and AR
head-mounted displays (HMD). Using HeadCross, users control the pointer with head …

In this paper, we explore alternative TV menu control methods, focusing specifically on older
users. We investigated performance and acceptance of freehand gestures by implementing …
