Paper and Poster Accepted for ACM VRST 2024: AR Pattern Guidance and VR Text Input Modalities
We are excited to announce that both our paper and poster have been conditionally accepted for presentation at the ACM Symposium on Virtual Reality Software and Technology (VRST) 2024, which will take place in Trier, Germany.
Paper: Evaluation of AR Pattern Guidance Methods for a Surface Cleaning Task
Our full paper titled “Evaluation of AR Pattern Guidance Methods for a Surface Cleaning Task.” has been conditionally accepted.
Abstract
We investigate the efficacy of augmented reality (AR) in enhancing a cleanroom cleaning task by implementing various pattern guidance designs. Cleanroom cleaning is an example of a surface coverage task that is hard to execute where the pattern should be followed correctly and the entire surface should be covered. We developed an AR guidance system for the cleaning procedure and evaluated four distinct pattern guidance methods: (1) breadcrumbs, (2) examples, (3) middle lines, and (4) outlines. We also varied the scale of the instructions, where information is present either on the entire surface or shows the instructions as a single step when they are necessary. To measure the performance, accuracy, and user satisfaction associated with each guidance method, we conducted a large-scale (n=864) between-subjects study. Our findings indicate that the single-step instructions proved to be more intuitive and efficient than the full instructions, especially for the breadcrumbs. We also discussed the implications of our results for the development of AR applications for surface coverage and pattern optimization, providing a multitude of observations related to instruction behaviors.

Poster: Exploring Alternative Text Input Modalities in Virtual Reality: A Comparative Study
Our poster, which is based on the Master’s thesis of our student Mathias Jans, is titled “Exploring Alternative Text Input Modalities in Virtual Reality: A Comparative Study.”. This work will be presented as a poster at the conference.
Abstract
Text input in Virtual Reality (VR) is crucial for various applications, including communication, search, and productivity. We compare different keyboard designs for text entry in VR, taking advantage of the flexibility and the tracking options that are available for a 3D environment. To assess the differences between the input modalities and the spatial keyboard layouts void of the user experience with specific keyboard layouts, the Dvorak keyboard layout was used. Four different settings were included in the comparison: (a) a floating keyboard with finger pointing input, (b) a keyboard attached on the back of the hand with finger pointing input, (c) a floating keyboard with eye tracking and finger pinch input, and (d) a keyboard laid out over a rolling shape with finger pointing input. Keyboards (b), (c), and (d) can move in 3D space, while keyboard design (a) is fixed. (a) and (d) showed similar typing efficiencies, however, users reported an increase in perceived usability and lower physical demand for keyboard design (d). Users also reported a higher physical demand, effort, and annoyance for keyboard design (b), and a lower physical demand for keyboard design (c), with higher mental demand, effort, and the highest error rate.

We are thrilled to share these findings with the community and look forward to the discussions they will spark at VRST 2024!
