Use of Haptics for the Enhanced Musuem Website-USC Interactive Art Museum Our mission for the Enhanced Museum project is to explore new technologies for the exhibition of three-dimensional art objects (Goldberg, Bekey, Akatsuka, and Bressanelli, 1997; McLaughlin, 1998; McLaughlin, Goldberg, Ellison, and Lucas, 1999; McLaughlin and Osborne, 1997; Schertz, Jaskowiak, and McLaughlin, 1997). Although it is not yet commonplace, a few museums are exploring methods for 3D digitization of priceless artifacts and objects from their sculpture and decorative arts collections, making the images available via CD-ROM or in-house kiosks. For example, the Canadian Museum of Civilization has collaborated with Ontario-based Hymarc to use the latter's ColorScan 3D laser camera to create three-dimensional models of more than fifty objects from the museum's collection (Canarie, Inc., 1998; Shulman, 1998). A similar partnership has been formed between the Smithsonian Institution and Synthonic Technologies, a Los Angeles-area company. At Florida State University , the Deparment of Classics is working with a team to digitize Etruscan artifacts using the RealScan 3D imaging system from Real 3D (Orlando, Florida), and art historians from Temple University are collaborating with researchers from the Watson Research Laboratory's visual and geometric computing group to create a model of Michaelangelo's Pieta with the Virtuoso shape camera from Visual Interface (Shulman, 1998). In collaboration with our colleagues at USC's accredited art museum, the Fisher Gallery, our IMSC team is developing an application for the Media Immersion Environment that will not only permit museum visitors to examine and manipulate digitized three-dimensional art objects vi... ... middle of paper ... ...fingers, see Hollins et al., 1993, below) have repeatedly been demonstrated by Lederman and her colleagues (Lederman, 1985; Lederman, Thorne, & Jones, 1986; Loomis & Lederman, 1986) to be functionally equivalent with respect to texture perception, in that touch modality does not seem to account for a significant proportion of the variation in judgments of such basic dimensions as roughness, even though the two types of touch may lead to different sorts of attributions (respectively, about the texture object and about the cutaneous sensing surface) and motor information should clearly be useful in assessing the size and distribution of surface protrusions and retractions. Active-passive touch is more likely to be equivalent in certain types of perceptual tasks; active touch should be less relevant to judgments of "hardness" than it is to assessments of "springiness".
