The Simputer Trust intends to take computing to those who find themselves on the other side of the digital divide. Designing with the third-world village in mind means circumventing the assumptions implicit in technophilic society — not the least of which is the presumption of literacy. Simputers are “shared devices that permit truly simple and natural user interfaces based on sight, touch and audio.” A Linux-powered PDA sporting an IML browser, “Tapatap” keystroke input, Web browser, email client, text-to-speech, and MP3 player, the device will sell for Rs 9000 (around $200US).
