 DVD-thermometer

 

A multimedia thermometer of great visual impact.

 

The basic idea can be adapted to a variety of practical situations. The application as a public thermometer for hotels, malls, showrooms, stations, airports and tourist sites is straightforward. Thermometers per se are unquestionably useful, but the multimedia impact and low cost of the DVD-thermometer prospects new uses, especially when the possibility of adding advertisements is considered.
Potential applications include talking “Please-take-a-number” displays, interactive product selectors (e.g. to select the right glue or paint, or to see how a new drill works), and colorful, dramatic displays for any sort of measurement.
