This paper presents an approach that utilizes Visible Light Communication (VLC) to generate landmark route and alert instructions for supporting people's wayfinding activities. The system comprises ceiling luminaries serving as transmitters, which transmit map information, alerts, and path messages. Optical receivers collect this information in real time, providing users with the most optimal route to avoid congestion. Tetrachromatic identifier white sources are used for lighting and different data channels. The data is encoded, modulated, and converted into light signals. Mobile optical receivers capture data, determine their location, and read transmitted data simultaneously. Bidirectional communication allows users to interact with the received information. The system calculates the best route considering static or dynamic destinations, including buddy wayfinding services. Results show that the system enables self-location, travel direction deduction, and efficient navigation towards static or dynamic locations.
