Title: Multitoe: High-Precision Interaction with Back-Projected Floors Based on High-Resolution Multi-Touch Input
Author: Thomas Augsten, Konstantin Kaefer, René Meusel, Caroline Fetzer, Dorian Kanitz, Thomas Stoff, Torsten Becker, Christian Holz, and Patrick Baudisch
Venue: UIST 2010
Summary:
This paper explores a new extension of the touch surface technologies. Their goal was to create something similar to tabletop computers, but not as limited by size and reach. Thus, they devised a system that one could use with the feet and spans the entire floor. Users are mapped to specific positions, therefore distinguishing between users and allowing multiple user functionality. To overcome the issue of people inadvertently setting off the touch screen, the user must jump, but there is also a more precise mode that the user can activate. Also, since the foot is about 200 times larger than the fingertip, the system condenses the foot into a single, customizable "hotspot." The design is based on "frustrated total internal reflection" (FTIR) with a high camera resolution, and this is what allows direct manipulation. Additionally, the position of the body and head will play a role in the interaction with the device, and wil be calculated based on weight distribution statistics. They are currently creating the larger prototype.
Discussion:
I like that they are thinking big here. I do think that people will be unlikely to use their feet, however. People like to use their hands. People are generally much more coordinated using their hands as opposed to their feet. I think some sort of cane or long device would be a good support to the foot based interactions. Also something to mimic the mouse would be a good idea as well, in my opinion. I don't think this is something that we will see in very many households though, similar to the tabletop computers. Some businesses might be able to make use of it, but it should be interesting to see how they market this and who they target with this system. I found this read pretty interesting overall.
