3D gesture based systems are becoming ubiquitous and there are many mid-air hand
gestures that exist for interacting with digital surfaces and displays. There is no well defined …

Featured Application Advanced mixed realities 3D interaction, multimodality complex

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 …

Virtual reality learning environment is a virtual learning environment created by the use of
virtual reality technology, which expands the physical learning environment and provides …

Model-based evaluation has been widely used in HCI. However, current predictive models
are insufficient to evaluate Natural User Interfaces based on touchless hand gestures. The …

Due to the possibilities provided by such technologies to provide people with live immersive
virtual worlds, Extended Reality (XR) technologies such as virtual (VR), augmented (AR) …

This article presents a new natural user interface to control and manipulate a 3D animation
using the Kinect. The researchers design a number of gestures that allow the user to play …

This paper introduces an interaction method allowing virtual reality (VR) users to interact
with virtual objects by blowing air. The proposed method allows users to interact with virtual …

This work presents a new comparative study for manipulating animated 3D content on a
large scale display using two user interaction mechanisms. The first interaction mechanism …

This article presents the results of exploratory research to examine the accessibility
limitations that eXtended Reality (XR) presents for people with reduced mobility. The …
