This specification describes apparatus, computer-implemented methods, and systems for interacting with computing systems using finger-specific input. In one general embodiment, a finger-specific input device can identify and differentiate each finger of a user. For example, the finger-specific input device may be able to detect features of each individual finger, such as fingerprints or detectable finger attachments, and to determine a set of fingers using the input device by camera or other visual cue, among others. A user can use multiple fingers to interact with a computing system and generate commands based on the use of a particular finger, a particular combination of fingers, and particular gestures of specific finger or combination of finger movements. In some implementations, specific commands are assigned to corresponding fingers and/or finger-specific multi-touch gestures in a program environment. In some implementations, users can define specific commands for specific fingers and/or finger-specific multi-touch gestures.
