Abstract

This thesis studies the effects of haptic force feedback on 3D interaction performance. To date, Human-Computer Interaction (HCI) in three dimensions is not well understood. Within platforms, such as Immersive Virtual Environments (IVEs), implementing `good' methods of interaction is difficult. As reflected by the lack of 3D IVE applications in common use, typical performance constraints include inaccurate tracking, lack of additional sensory inputs, in addition to general design issues related to the implemented interaction technique and connected input devices. In total, this represents a broad set of multi-disciplinary challenges. By implementing techniques that address these problems, we intend to use IVE platforms to study human 3D interaction and the effects of different types of feedback. A promising area of work is the development of haptic force feedback devices. Also called haptic interfaces, these devices can exert a desired force onto the user simulating a physical interaction. When described as a sensory cue, it is thought that this information is important for the selection and manipulation of 3D objects. To date, there are a lot of studies investigating how best to integrate haptic devices within IVEs. Whilst there are still fundamental integration and device level problems to solve, previous work demonstrates that haptic force feedback can improve 3D interaction performance. By investigating this claim further, this thesis explores the role of haptic force feedback on 3D interaction performance in more detail. In particular, we found additional complexities whereby different types of haptic force feedback conditions can either help but also hinder user performance. By discussing these new results, we begin to examine the utility of haptic force feedback. By focusing our user studies on 3D selection, we explored the influence of haptic force feedback on the strategies taken to target virtual objects when using either `distal' and `natural' interaction technique designs. We first outlined novel methods for integrating and calibrating large scale haptic devices within a CAVE-like IVE. Secondly, we described our implementation of distal and natural selection techniques tailored to the available hardware, including the collision detection mechanisms used to render different haptic responses. Thirdly, we discussed the evaluation framework used to assess different interaction techniques and haptic force feedback responses within a common IVE setup. Finally, we provide a detailed assessment of user performance highlighting the effects of haptic force feedback on 3D selection, which is the main contribution of this work. We expect the presented findings will add to the existing literature that evaluates novel 3D interaction technique designs for IVEs. We also hope that this thesis will provide a basis to develop future interaction models that include the effects of haptic force feedback.
