  • Publication number: 20070194558
    Abstract: Selected patterns of lights are displayed on a recreational conveyance such as a snowboard according to the motion of the board. A selection of patterns is stored in a processor memory, the motion of the board is measured (for example with accelerometers) and a pattern is selected from memory based on the measured motion. Then lights on the board are blinked on and off in the selected pattern. Accelerometer inputs are analyzed and a series of states is derived for each accelerometer axis. A series of states can be analyzed as a set to select a different pattern. Also, the magnitude of the states (such as duration, speed, or intensity) may affect the pattern selected. The process may be adaptive, so that the analyzing step further analyzes user weight or past snowboarding style to set adaptive thresholds for selecting patterns.
