A low cost smell detection system for multimedia applications

Abstract

A multimedia system is one of the most widely used consumer electronics environments today in which humans can work or communicate through multi-sensory interfaces. Existing multimedia systems include audio systems and video displays that make use of the human auditory and visual systems. The minor sensory information namely, smell, taste and touch are generally not used. In order to use smell in multimedia environments, smell detectors and producers are required. We propose a low cost smell detector that can be used in a multimedia environment. It is shown that a crude smell detection system, which can detect tens of smells can be developed at a low cost, compared to that of typical systems used in industrial applications.
