Week 13 Summaries
Omnitouch :
The paper introduces a novel device from Microsoft. It is a shoulder worn system which aims to be used as an input/output device enabling multi-touch operations for input. It utilizes depth sensing and projection technologies to enable the multi-touch operations. Interfaces from the system can be projected on any surface ranging from table tops to body parts. The system makes use of finger tracking to provide the on-go interactive features. It detects whether the finger is hovering over or touching the surface producing inputs similar to that of a mouse or a touch screen. But hindering feature to the systems success could be it’s size and the mode of usage. It is not as compact as smartphone and cannot be carried like a tab or a smart phone. I may come in handy in places where the system needs to be fixed but that would defeat the purpose of the system as a whole.
Proprioception :
One of the big problems with VR is to make it immersive. One way to do this is to introduce haptic feedbacks. More a person is able to interact more he feels immersed into the environment. In this paper authors propose a framework for interaction in the virtual environment based on proprioception, a persons’s sense of the position and orientation of his body and limbs. In the paper they describe 3 forms of body-relative interactions:
Direct Manipulation, Physical Mnemonics, Gestural Actions. They use automatic scaling to bring the far away objects closer to the user to enable manipulation using the proprioceptive cues. As with all other existing virtual environment techniques there is a lot of scope for improvement before it can be put to use.
