Touchscreens have been studied and developed for a long time to provide user-friendly and
intuitive interfaces on displays. This paper describes the touchscreen technologies in four …

Conventional wisdom holds that laser-based systems cannot handle high mobility due to the
strong directionality of laser light. We challenge this belief by presenting Lasertag, a generic …

Touchscreens enable intuitive mobile interaction. However, touch input is limited to 2D touch
locations which makes it challenging to provide shortcuts and secondary actions similar to …

Jitter and lag severely impact the smoothness and responsiveness of user experience on
vision-based human-display interactive systems such as phones, TVs, and VR/AR. Current …

Research is exploring novel ways of adding haptics to VR. One popular technique is haptic
retargeting, where real and virtual hands are decoupled to enable the reuse of physical …

Users' expectations about systems alter how they interact with them, thereby influencing
their experience. Latency is also known to alter experience and performance in interactive …

Motion tracking technologies and avatars in virtual reality (VR) showing the movements of
the own body enable high levels of presence and a strong illusion of body ownership (IBO) …

Studies have shown certain game tasks such as targeting to be negatively and significantly
affected by latencies as low as 41ms. Therefore it is important to understand the relationship …

Touch surfaces are widely utilized for smartphones, tablet PCs, and laptops (touchpad), and
single and double taps are the most basic and common operations on them. The detection …

Touchscreens are the dominant input mechanism for a variety of devices. One of the main
limitations of touchscreens is the latency to receive input, refresh, and respond. This latency …
