In a presentation sprinkled with self-deprecating jokes and a finale featuring rock guitarist Slash, Gates predicted that people would interact more naturally with technology through methods like speech and touch over the next decade. It is a prediction Gates has made for years, touting devices like the tablet computer, which have had slow adoption.
However, devices like Apple Inc iPhone and Nintendo Co Ltd's <7974.os> Wii motion-sensing video game machine are proving that more "natural" user interfaces have a broad appeal with consumers.
