Personalised virtual twin. Composite image of a hand holding a mobile telephone displaying a personalised virtual twin. The 3-D image (avatar) can be used to personalise computer displays and computer game characters, as well as mobile phone messages. The 3-D model is created from two views of a person's head. The two views, one in profile and one face-on, are combined using specialised software. The 3-D model is flexible, and can be animated to express emotions and simulate speech. This technology was created by Digimask, of Surrey, England.
