Many human-computer interaction technologies are currently mediated by physical transducers such as mice, keyboards, pens, dials, and touch-sensitive surfaces. Explore the feasibility of muscle-computer input: an interaction methodology that directly senses and decodes human muscular activity rather than relying on physical device actuation or user actions that are externally visible or audible.
