Abstract

The research explores the design and implementation of a virtual reality (VR) object interaction system with complex close-range hand interactions. This paper presents an object interaction system which would allow developers to easily add additional or accessory action requirements to an interaction, beyond simply selecting a button upon directing the controller to an intended target. Test environments were built using this system, implementing several close-range complex interactions: twist, lever, and hit. In the final test environment developed, these three were implemented as six possible task actions that the system could recognize. Although these actions are at different levels of usability, this presents the potential of how the same gestures can be used in different ways within a VR environment.

Two user studies were conducted to better understand how users experience these implemented interactions. These studies investigated how users experienced the developed interactions in different levels of interaction complexity. In both studies, it was found that users generally preferred interactions which had these accessory actions.
