A display for supporting ownership of virtual arms

Abstract

To enable convincing first-person interactions involving object manipulation, virtual reality systems need to represent the user's body in the virtual environment. Virtual body parts, particularly the arms and hands, must appear in the correct perceived spatial positions in a first-person view so that users can “take ownership” of them. One current method to achieve this goal is head-mounted displays, but they have cost and motion sickness problems. Other methods such as table-top projections have problems with image occlusion by the user's
own limbs. In this paper we describe a low-cost alternative
using a mirrored horizontal display which places virtual arms in the correct position relative to the user on a table top.
We hypothesized that, compared to a normal monitor, our display provides improved subjective ownership of virtual limbs while maintaining equivalent ease of use. Questionnaires on healthy subjects showed that they found it easier to induce selfownership of virtual arms using our display. We also compared a virtual rubber hand illusion using our display with a real rubber hand illusion and found comparable ownership results.
We conclude that our display can support improved ownership of virtual arms compared to a normal vertical display.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
