“…More and more computers are hidden inside social artifacts ranging from washing machines to teddy bears. These hidden computers are meant to make these artifacts responsive, fun, intelligent, easy to use, and comfortable, that is, more humane than previous artifacts (Laurel, 1990; Schneiderman, 1987). Other computers are designed to seem human-like through interfaces that incorporate speech and/or speech recognition (e.g., Itou, Hayamizu, & Tanaka, 1992), auditory and kinesthetic feedback (Gaver, 1986; Takemura & Kishino, 1992), social intelligence (Binick, Westbury, & Servan-Schreiber, 1989; Resnick & Lammers, 1985), emotional response (Elliott, 1994), directed animation (Ball et al, 1994; Hayes-Roth, Sincoff, Brownston, Huard, & Lent, 1995), or a talking face on the screen (Sproull, Walker, Subramani, Kiesler, & Waters, in press).…”
