Abstract: The present invention relates to a wireless proximity guidance system and a firmware-implemented method for guiding a user toward an object using progressive haptic feedback. A wireless transmitter associated with an object periodically broadcasts wireless transmissions, and a receiver obtains received signal-strength measurements corresponding thereto. Successive signal-strength measurements are digitally filtered to suppress noise and short-duration fluctuations and are evaluated using separate activation and deactivation thresholds defining a hysteresis region, thereby reducing repeated switching of haptic feedback near a threshold. When proximity guidance is active, the filtered signal strength is continuously or substantially continuously mapped over a predetermined range to a target haptic intensity that increases with signal strength. Temporal variation of filtered signal strength is further analysed to determine whether the receiver is generally approaching or retreating from the transmitter, and the target haptic intensity is adjusted according to the determined trend. An actuator-drive value is progressively ramped toward the target intensity to prevent abrupt tactile transitions. When valid wireless transmissions are absent for a predetermined timeout interval, the haptic output is progressively faded instead of being abruptly terminated. The processing is implemented principally through receiver firmware using wireless signal-strength information available from the existing wireless radio and therefore does not require additional distance, directional or motion-sensing hardware. The invention is applicable to item finders, asset and tool trackers, mobility aids and assistive devices for visually impaired users.
