Mission confiée

Context :

This internship will take place in the Seamless team at Inria Rennes. The team specializes in virtual reality and human-computer interactions. During the internship, the intern will explore a multi-disciplinary field that encompasses virtual interactions (programming) and haptic feedback (mechanical engineering, CAD, and robotics).

Many virtual reality applications require users to walk through a virtual environment (e.g.,  rehabilitation, games, virtual visits, etc). Due to space constraints and to minimize user fatigue, these applications often use a technique called "Walking-In-Place." This approach allows users to control the walking of their virtual character while remaining in the same physical location by performing movements like raising their legs, swinging their arms, or cycling. The technique is efficient; however, since users are not actually walking, the experience can feel less engaging than real walking.

To enhance the user experience of walking, compelling virtual environments can be implemented (e.g., forest, beach, mountain) and haptic (touch) feedback corresponding to the different virtual ground (e.g., mud, sand, snow) can be implemented. Until now, the main haptic strategy consisted of using vibrations underfoot to reproduce different ground, but this feedback is unrealistic and uncomfortable for some users. Another approach will be explored in this internship.

Assignements:

The internship aims to design haptic feedback to simulate different ground materials and render a compelling experience of walking to Virtual Reality users. The intern will implement the walk of a virtual character in various scenes in Virtual Reality. The virtual walking movement will be based on users’ movements tracked by the Virtual Reality system. He/She will design a haptic system to simulate different materials and conduct a user study to test its interest in user experience. The internship could lead to writing a scientific paper, depending on the advancement.
