This paper contributes a novel interaction opportunity of using our body as an antenna to receive electromagnetic noises from the environment. Experimented in a home setting, by using a simple analog-to-digital converter on the body, one can obtain a lot of information such as whether he is touching the wall, the location within the home, the touch positions (e.g., those surrounding a switch), etc. Besides these core findings, the paper also steps further to explore more fine-grained knowledge such as which hand and finger is touching the wall. Following this, the authors discuss their work, limitations, future work and potential applications.
- Core findings:
- Wall touch;
- Location in home;
- Touch position on wall;
- Body contact location (does not matter);
- Appliance classification;
- Number of hands;
- Proximity to wall;
- Continuous position along wall;
- Interaction switch off (does not matter);
- Number of fingers
- The Introduction offers a very concise and delicate review of current sensing and input technology in ubiquitous computing.
- “The human body as an antenna” section offers a very complete review of related work (not limited in HCI).
- Overall, the paper is very well written.
- A more detailed vision of its application:
- Location-based: used on spatial memory;
- Touch-point + number-of-hands == multi-touch interface;
- Proximity-to-wall + telling-appliance == device-to-device/people-to-device proxemic interaction.
