Addressing the challenges of distant pointing, we present the feedforward static targeting assistance technique VTE: Voronoi-based Target Expansion. VTE statically displays all the activation areas by dividing the total screen space into areas such that there is only one target inside each area, also called Voronoi tessellation. The key benefit of VTE is in providing the user with an immediate understanding of the targets' activation boundaries before the pointing task even begins: VTE then provides static targeting assistance for both phases of a pointing task, the ballistic motion and the corrective phase. With the goal of making the environment visually uncluttered, we present a first user study to explore the visual parameters of VTE that affect the performance of the technique. In a second user study focusing on static versus dynamic assistance, we compare VTE with Bubble Ray, a dynamic Voronoi-based targeting assistance technique for distant pointing. Results show that VTE significantly outperforms the dynamic assistance technique and is preferred by users both for ray-casting pointing and relative pointing with a hand-controlled cursor. |
