The
sense of touch is an important sensory channel in many animals and some plants.
Our senses inform to us when our hands touch something. Computer input devices
are indifferent to human contact as there is no reaction from software in the
event of making, maintaining or breaking physical contact like touches or
releases.
Thus, touch sensing input devices offers numerous possibilities
for novel interaction techniques. Touch sensor technology is slowly replacing
the mechanical objects like mouse and keyboard.
A touch sensor detects touch or near proximity
without relying on physical contact. Touch sensors are making their way into
many applications like mobile phones, remote controls, control panels, etc.
Present day touch sensors can replace mechanical buttons and switches.
Touch sensors with simple rotational sliders, touch pads and
rotary wheels offer significant advantages for more intuitive user interfaces.
Touch sensors are more convenient and more reliable to use without moving
parts. The use of touch sensors provides great freedom to the system designer
and help in reducing the overall cost of the system. The overall look of the
system can be more appealing and contemporary.
