| abstract |
A tactile grammar method for implementing a touch-based user interface for a Computer Aided Design software application is provided. A tactile array sensor responsive to touch of at least one finger of a human user provides tactile sensing information that is processed to produce a sequence of symbols and numerical values responsive to the touch of the finger. At least one symbol is associated with one or more gesteme, and each gesteme is comprised by at least one touch gesture. A sequence of symbols is recognized as a sequence of gestemes, which is in turn recognized as a sequence of touch gestures subject to a grammatical rule producing a meaning that corresponds to a command. The command is submitted to a Computer Aided Design software application which executes the command, wherein the grammatical rule provides the human user a framework for associating the meaning with the first and second gesture. |
