Effects of Virtual Reality–Based Multimodal Audio-Tactile Cueing in Patients With Spatial Attention Deficits: Pilot Usability Study

Effects of Virtual Reality–Based Multimodal Audio-Tactile Cueing in Patients With Spatial Attention Deficits: Pilot Usability Study

Additionally, for the application of the tactile cue, a special cushion as an inlay piece for the HMD was used, as described by Knobel et al [29]. The cushion contains 6 coin vibrators symmetrically distributed over the forehead. Each coin vibrator could be started individually. The sound was presented via over-ear headphones. The main goal of the bird search task was to detect the appearing birds as quickly as possible. The task took place in a virtual environment and contained 3 main features (Figure 2).

Development of a Search Task Using Immersive Virtual Reality: Proof-of-Concept Study

Development of a Search Task Using Immersive Virtual Reality: Proof-of-Concept Study

To assess acceptance, usability, and participant's perception of the visual search task and of the VR system, 3 questions from the System Usability Scale (SUS) [49] were used, as previously reported by Gerber et al [50] and Knobel et al [51]. The questions were answered using a 5-point Likert-scale, ranging from “fully disagree” to “fully agree.” The mean score across all questions was calculated for each participant.
