MPP3D: Multi-Precision Pointing using the 3rd Dimension
This work addresses distant pointing inefficiencies for users of high-resolution displays, but it is incremental as it builds on existing pointing methods with precision adjustments.
The paper tackled the problem of inefficient and inaccurate distant pointing for high-resolution displays by proposing MPP3D, a technique that uses hand positioning in three dimensions to adjust movement precision, resulting in improved pointing efficiency and accuracy for usual computer operations.
Distant pointing is still not efficient, accurate or flexible enough for many applications, although many researchers have focused on it. To improve upon distant pointing, we propose MPP3D, which is especially suitable for high-resolution displays. MPP3D uses two dimensions of hand positioning to move a pointer, and it also uses the third dimension to adjust the precision of the movement. Based on the idea of MPP3D, we propose four techniques which combine two ways of mapping and two techniques for precision adjustment. We further provide three types of mapping scheme and visual feedback for each technique. The potential of the proposed techniques was investigated through experimentation. The results show that these techniques were competent for usual computer operations with a cursor, and the adjustment for pointing precision was beneficial for both pointing efficiency and accuracy.
