Tangible display systems: direct interfaces for computer-based studies of surface appearance

Tangible Images: Bridging the Real and Virtual Worlds

“…Our goal in designing e a proof-of-concept tangible imaging system that achie urfaces such as paintings, prints, etc.. The tangiBook w aptop computer (Apple MacBook Pro) that incorporated The laptop's high-resolution LCD display screen bac dware and software supported realistic rendering, and camera supported direct manipulation and user tracki , left), tilting the laptop or moving in front of it produ ppearance (color, gloss, texture) of the rendered surfa he tangiBook were promising, the laptop form-factor wa hen tablet computers became available we implemente called tangiView [2]. Figure 1 ( as a ed a the tablet device provides a more natural interface for the low relief surfaces we were interested in simulating.…”

“…We get a lot of information from interacting with surfaces, either through direct manipulation, or through observing a surface from different viewpoints, and conventional images do not support either of these behaviors. For this reason we have been working to create tangible imaging systems [1][2][3][4], that harness the power of digital modeling, computer graphics, and modern mobile computing platforms to produce new kinds of images that look and behave much more like the surfaces they represent. Figure 1 shows one implementation of a tangible imaging system, the tangiBook, based on an off-the-shelf laptop computer.…”

Tangible imaging systems

“…We are developing tangible imaging systems [1][2][3][4] that merge the power of computer graphics with the direct interaction capabilities of modern mobile devices to create rich digital representations of three-dimensional objects that can be viewed and manipulated as naturally as real ones, with the added benefit that the shapes, surface properties, and lighting of the objects can be changed under user control. Figure 1 shows examples of the four systems we have developed that will be reviewed in this paper: tangiBook -our first implementation of the concept on a laptop computer; tangiView -a Figure 1: Tangible imaging systems (left to right): The first generation tangiBook system developed using an off-the-shelf laptop computer; the tangiView system implemented on a tablet device; the tangiPaint application that allows the creation of paintings with rich surface properties; the phantoView system that allows tangible interaction with three-dimensional object models.…”
