VoxBox: a Tangible Machine that GathersOpinions from the Public at Events
This paper gives an introduction to an interactive machine called VoxBox. The idea of VoxBox has come from the fact that people are very reluctant to do surveys. In order to increase the participation of people, they have made this tangible machine that gathers public opinions. VoxBox is consisted of various switches that show different questionnaires. People can view their progress status, and they are given incentives as well. When they complete the given survey they can also review the result as well as the research findings.
Touchless Interaction in Surgery
The issue lies in maintaining sterility while having hands-on control over the medical image in the surgical setting. So the best solution could be developing touch-less interactive device that allows surgeons to have directly manipulate and navigate the images. And recent innovation of "Kinect" has made it easier to develop such device. One example is the Sunnybrook system from a hospital in Toronto. They use Kinect sensors to review MRI and CT images in the operating theatre. However, the number of gestures they can use is limited. Though it sounds like a constraint to this design, limited gesture actually poses more positive sense. That is, it may increase the learnability of the system. It may also reduce "gesture bleed" where the system misinterprets a set of kinetic information. Nevertheless, beyond its positive aspect of simplicity, Sunnybrook system also raises problems when it needs more complicated manipulation. So the recent researches have suggested using multi-hand gesture combinations and even voice recognition system. There are other concerns as the socio-technological concerns "including collaboration and control, engagement and disengagement, and image inspection with one hand, two hands, and hands-free." Overall, the paper gives an overview of the feasibility of the touch-less interaction in surgery and its possible challenges as well.
