Comparing Controller With the Hand Gestures Pinch and Grab for Picking Up and Placing Virtual Objects
This work addresses usability issues for AR/VR/MR users by offering more natural and efficient interaction methods, though it is incremental as it builds on existing gesture-based systems.
The paper tackled the problem of unnatural and limiting pinch gestures for grabbing virtual objects in AR/VR/MR applications by proposing and comparing alternative implementations, finding that the proposed techniques improved performance and accuracy with measured results.
Grabbing virtual objects is one of the essential tasks for Augmented, Virtual, and Mixed Reality applications. Modern applications usually use a simple pinch gesture for grabbing and moving objects. However, picking up objects by pinching has disadvantages. It can be an unnatural gesture to pick up objects and prevents the implementation of other gestures which would be performed with thumb and index. Therefore it is not the optimal choice for many applications. In this work, different implementations for grabbing and placing virtual objects are proposed and compared. Performance and accuracy of the proposed techniques are measured and compared.
