The field of tangible interaction currently studies how the user interaction with physical products can be improved through physical feedback, as a more direct experience. Here we explore this subject further with particular emphasis on the elements of visual attraction of illuminated surfaces as an early factor in the interaction process. Richard Appleby is an experienced industrial designer who has developed many consumer products where the surface definition and visual language has had a significant impact on the perceived values and tangibility of the product. These changing surface interactions should not be difficult or challenging, but intuitive and enjoyable to live with. The systems may be complex, but the way they reveal and offer their actions can heighten our awareness and sensitivity in new and unique ways. It is a question of subtlety and detail. As the surfaces we interact with have the intelligence to appreciate a much wider range of human conditions and user feedback, their response can be attuned more closely to our different senses and feelings, particularly as this leads to more subjective and sensorial types of interaction, with varying dimensions and magnitude. These surfaces change through colour and form that attract the user we\ud coin ‘tangible light interaction’. Particularly within the field of intelligent technologies, project examples show design concepts that support social interaction and remote communications in new ways
