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 …

Mid-air gesture-based systems are becoming ubiquitous. Many mid-air gestures control
different kinds of interactive devices, applications, and systems. They are, however, still …

Raycasting is the most common target pointing technique in virtual reality environments.
However, performance on small and distant targets is impacted by the accuracy of the …

The primary objective of this research is to understand how users manipulate virtual objects
in augmented reality using multimodal interaction (gesture and speech) and unimodal …

Browsing multimedia objects, such as photos, videos, documents, and maps represents a
frequent activity in a context of use where an end-user interacts on a large vertical display …

Mid-air gestural interaction with multiple targets (or devices) in the physical space presents
several challenges: gesture design gets more complex in the attempt to avoid gesture …

Touchless gesture interfaces often use cursor-based interactions, where widgets are
targeted by a movable cursor and activated with a mid-air gesture (eg, push or Pinch) …

Orchestrating digital devices in classrooms is challenging. We conducted an observational
study to understand how teachers manage multi-device classrooms involving tablets …

This research explores the design and evaluation of a webcam-based presentation tool that
enables presenters to directly interact with web content via free-hand gestures. Our …

Ray-casting is often used for object manipulation that intersects with the ray that uses the
intersection between rays extending from the user and a virtual object. In Augmented Reality …
