History[ edit ] One of the earliest applications of haptic technology was in large aircraft that use servomechanism systems to operate control surfaces. Here, the missing normal forces are simulated with springs and weights.
Appropriating the Body as an Input Surface Devices with significant computational power and capabilities can now be easily carried on our bodies. However, their small size typically leads to limited interaction space e. Since we cannot simply make buttons and screens larger without losing the primary benefit of small size, we consider alternative approaches that enhance interactions with small mobile systems.
One option is to opportunistically appropriate surface area from the environment for interactive purposes. For example, Scratch Input is technique that allows a small mobile device to turn tables on which it rests into a gestural finger input canvas. However, tables are not always present, and in a mobile context, users are unlikely to want to carry appropriated surfaces with them at this point, one might as well just have a larger device.
However, there is one surface that has been previous overlooked as an input canvas, and one that happens to always travel with us: Appropriating the human body as an input device is appealing not only because we have roughly two square meters of external surface area, but also because much of it is easily accessible by our hands e.
Furthermore, proprioception our sense of how our body is configured in three-dimensional space allows us to accurately interact with our bodies in an eyes-free manner.
For example, we can readily flick each of our fingers, touch the tip of our nose, and clap our hands together without visual assistance.
Few external input devices can claim this accurate, eyes-free input characteristic and provide such a large interaction area. In the paper linked below, we present our research on Skinput — a method that allows the body to be appropriated for finger input using a novel, non-invasive, wearable bio-acoustic sensor.

srmvision.com is also an active member in a number of national and international research projects. Inception in the s. A detailed survey of related research in the s was performed by Harmon,,.Although these surveys covered papers, a careful review of the references reveal that most of the papers addressed other sub-areas of robotics rather than directly contributing to tactile sensor srmvision.com example, it was realized .
Any device which senses information such as shape, texture, softness, temperature, vibration or shear and normal forces, by physical contact or touch, can be termed a tactile sensor.

Perhaps surprisingly, this disparity was encountered with both the fiction and the factual prose.
