Designing a Pinch Disable Mode for XR Devices
摘要
In this work, we design a pinch disable mode in order to mitigate a common user experience problem in AR/VR/MR devices: involuntary actions caused by misinterpretation of the device. Since the pinch is one of the most common actions to interact in immersive environments, being used to both select and grab and drag virtual objects, we designed a mode to disable the pinch action based on wrist rotation and taking into account that most of the pinch actions are made in a specific hand position. The aim is to avoid involuntary actions and improve the user experience. Moreover, we set up a user test to investigate how much the angle limitation of the mode influences the performance of usual tasks into a VR scene. Experienced users were asked to perform basic actions, and the designed restriction did not prevent users from performing the tasks, successfully disabling the pinch action when it was expected. The proposal can be used as a possible solution to prevent missclick, but more research is needed to address comfort and accuracy issues.
