Week 12 Summaries
A Survey of Design Issues in Spatial Input:
This paper explores design principles and issues designers need to account for when designing interfaces that will be used with spatial input. The paper goes into two major areas for spatial input, human perception and ergonomic concerns. Human perception of 3D space is key in designing interfaces because even though many things are possible when creating a virtual 3D space, how humans will perceive it just as important as what you can do in the space. With regards to ergonomics designers have to provide controls for input that users are able to interact with well enough to accomplish the tasks needed in the 3D environment. In their conclusion the authors ask questions based on what they saw from their research, of these questions the one I find most prevalent was: What design issues apply to both desktop interfaces and virtual reality interfaces? This question seems important because if issues are solved with desktop interfaces we should also look into how the solved desktop issue can be ported over to the 3D environment.
Exploring 3D Navigation: Combining Speed-coupled Flying with Orbiting:
This paper discusses many of the previous techniques for navigation in a 3D spaces and also introduces a new technique “Speed-coupled Flying with Orbiting.” The previous techniques that are looked at in the paper are: Object Manipulation, Ghost Copy, Inverse Fog/Scaling, Ephemeral World Compression, Possession, and Rubberneck Navigation. These techniques follow a taxonomy developed for navigation. The paper introduces a new navigation technique and runs experiments with it. The authors found that the new technique, speed-coupled flying with orbiting, is more efficient in letting users navigate a 3D space.
