Sixth sense is now practical. A camera attached to a computer connected to internet can act as a sensing device and provide various inputs to people. One such application is translation facility.
If a person having this application on his body, comes across a foreign language message at any place, the camera takes the image, the computer recognizes that the language is a foreign language and it will show the person the translation in his language. Now technology is available at even commercialization stage for this app.
Recently Star bucks and Nivea released this type of applications wherein mobile phone camera and web camera sense the image shown to them and respond with information in form of dance of Rihanna and various images with animation ability in case of Starbucks.
