Abstract:
An optical scanner is configured to scan multiple print portions of a body part such as a finger. The optical scanner identifies a first one of the print portions in an area of an optical surface. An event such as launching an application is generated based on identifying the first print portion in the area of the optical surface. In addition, various events can be generated based on different combinations of print portions in different areas of the optical surface.In a second embodiment, a property detector is configured to identify different properties of a sleeve in different areas of a surface. An event is generated based on the detection of a property of the sleeve in an area of the surface.
Abstract:
An optical scanner scans a first portion of a print of a body part such as a finger in a first area of an optical surface. The optical scanner detects a motion of the body part to a second area of the optical surface. This can be done in various ways. One way is for the optical scanner to detect a sliding motion of the body part to determine if most of the first portion of the print is in the second area. Another way is for the optical scanner to determine a rolling motion of the print based on a continuity of the print from the first area to the second area. A similar system and method is disclosed which detects a rolling motion of a body part by using a sleeve with multiple properties.
