Abstract
A touchless sensor device (110) for touchless signing and recognition is provided. The sensor device can include a recognition engine (114) for recognizing at least one finger sign (140), and a controller (120) for composing a text from the recognized at least one finger sign and providing predictive texting. A recognized pattern can be an alphanumeric character or a finger gesture. The controller can generate a trace (145) from the finger sign. The trace can include spatio-temporal information (153) that is characteristic to a touchless writing style. The controller can provide text messaging services, email composition services, biometric identification services, phone dialing, and navigation entry services through touchless finger signing.
