  Use of Virtual Interactive Techniques for personalized product design is
described in this paper. Usually products are designed and built by considering
general usage patterns and Prototyping is used to mimic the static or working
behaviour of an actual product before manufacturing the product. The user does
not have any control on the design of the product. Personalized design
postpones design to a later stage. It allows for personalized selection of
individual components by the user. This is implemented by displaying the
individual components over a physical model constructed using Cardboard or
Thermocol in the actual size and shape of the original product. The components
of the equipment or product such as screen, buttons etc. are then projected
using a projector connected to the computer into the physical model. Users can
interact with the prototype like the original working equipment and they can
select, shape, position the individual components displayed on the interaction
panel using simple hand gestures. Computer Vision techniques as well as sound
processing techniques are used to detect and recognize the user gestures
captured using a web camera and microphone.
