Abstract:
The paper describes an approach that utilizes Visible Light Communication (VLC) to generate landmark route and alert instructions for supporting people's wayfinding activities. The system consists of multiple transmitters, which are ceiling luminaries that transmit map information, alerts, and path messages necessary for wayfinding. Optical receivers are used to collect this information. The system operates in real time, providing users with the most optimal route to their destination, thereby helping them avoid congested areas. The transmitters employ tetrachromatic identifier white sources, which serve the dual purpose of providing lighting and different data channels for each chip. The data is encoded, modulated, and converted into light signals. By employing joint transmission, mobile optical receivers can capture data at high frame rates, determine their own location, and simultaneously read transmitted data from each transmitter. The communication is bidirectional, allowing users to interact with the received information. The system calculates the best route through the venue, taking into account static or dynamic destinations. Additionally, the paper mentions the consideration of buddy wayfinding services. According to the results presented, the system not only enables self-location but also deduces the travel direction and interacts with the received information. This optimization process helps users navigate efficiently towards their desired destination, whether it is a static or dynamic location.
