Radial Text Input in Virtual Reality Jan Niklas Schlichting, Ishan Sharma Guided By: Dr. Michael Kipp

Motivation

Textual input in VR • Browsing • Texting • Creating profiles • Chatting • Inputting login information • Contact forms • Commenting

Existing input methods • Independence from • Fastest 15 WPM • Natural • Body engagement • Least fatiguing controller • Fatigue • Fatigue Fatigue • Slow • Fatigue • Lack of feedback • Lack of feedback Lack of feedback • Frustrating • Lack of feedback • Greater space • Fixed position of Need for focused • Unnatural mapping vision requirements hands of keys

Technical Realization

User Tests • 6 participants (21.75 YO) • 2 Sessions • Speed and accuracy are measured by counting WPM speed and Error rate • In order to measure fatigue, standard NASA TLX survey is used

Results: Speed CP = Controller Pointing, RDF = Radial Design Front, RD = Radial Design

Result: Fatigue

Result: User Preference
