KnobCollector: Custom Device Controller for Dynamic Real-Time Subjective Data Collection in Virtual Reality

Abstract

Real-time data collection in immersive virtual reality can be difficult due to the visual obstruction to the real-world. Furthermore, subjective data collection is conducted post-task, reducing the information of detailed user responses during a task therefore potentially missing critical events, subtle difference, or issues not obvious to a user. In this paper we present, KnobCollector, a custom device controller for dynamic real-time collection of subjective user data during an experimental. We conducted a user study with the KnobCollector to demonstrate the feasibility of use during a virtual reality task. Our results provide more rich data sets of user feedback during the virtual reality experience and could be used for future user studies in virtual reality environments.
