low-cost-VR Heading

Object selection is one of most common yet one of the most important tasks performed in a Virtual Reality (VR) interface. For instance, manipulation of any virtual object is not possible without object selection. Hence, poorly designed selection techniques often have a significant impact on the overall user experience and satisfaction. To best of our knowledge, there are no studies comparing input methods of object selection in commonly used HMD viewers (e.g. Google Cardboard or similar low-cost HMD viewer). This experiment is an attempt to investigate the best input method for object selection in VR, especially VR experienced in low-cost HMD viewer. We compare two input methods (a) dwell gaze and (b) combined touch & gaze to study task completion time, error rates, user preference, comfort, ease of use and satisfaction among users. The object selection was done in 3 Virtual Environment (VE) - (i) sparsely populated VE (ii) densely populated VE and (iii) occluded densely populated VE.  To realize this experiment,

We have conducted the study with 30 university students (8 female and 22 male) with a mean age of 22.3. The participants did not have any prior experience with VR interfaces. For this experiment, we developed a virtual supermarket with product displayed on the shelf. The users were asked to select a specific product given during each task. We are currently in the process of analyzing the data. We will soon publish the results here and through a publication
