Study and design of interaction techniques to facilitate object selection and manipulation in virtual environments on mobile devices

Abstract : The advances in the field of NUIs (Natural User Interfaces) can provide more and more guidelines for designers to develop efficient and easy-to-use techniques for 3D interaction. In this context, mobile devices attract much attention to design 3D interaction techniques for ubiquitous usage. Our research work focuses on proposing new techniques to facilitate object selection and manipulation in virtual environments on mobile devices. Indeed, the efficiency and accuracy of object selection are highly affected by the target size and the cluster density. To overcome the fingertip occlusion issue on Smartphones, we have designed two touchbased selection techniques. We have also designed one freehand hybrid technique for selection of small objects displayed at a distance. To perform constrained manipulation on Tablet-PCs, we have proposed a bimanual technique based on the asymmetrical model. Both hands can be used in collaboration, in order to specify the constraint, determine the manipulation mode, and control the transformation. We have also proposed two other single-hand manipulation techniques using identified touch inputs. The evaluations of our techniques demonstrate that they can improve the users’ interaction experience on mobile devices. Our results permit also to give some guidelines to improve the design of 3D interactions techniques on mobile devices.
