For centuries, humans have used light for communication, positioning and sensing purposes. With the ongoing rapid advancements in the field of Light emitting diodes (LED), photosensitive devices and the associated electronic components these applications of light, gain more and more relevance in our modern digitized world. Visible light communication (VLC), Visible light positioning (VLP) and Visible Light sensing are ideal candidates for realization of novel communication and sensing solutions, whilst the high requirements regarding privacy, complexity and resource/energy can be met.

Based on the introduction of the main principles of these Visible Light Technologies, current applications will be highlighted, outlining the major advantages compared to other technological approaches as well as discussing current limitations. In particular, based on the already obtained results of the ongoing Project Vilipa, the future possibilities of these approaches are elaborated.

Andreas Peter Weiss completed his master’s degree in Telematics at Graz University of Technology in 2008 and his PhD at Alpen-Adria-Universität Klagenfurt in 2012. From 2012 to 2018 he worked in the field of research and development of digital circuit design, signal processing and algorithm design at a renowned manufacturer in the field of measurement technology. Since 2018 he is member and since 2022 head of the Smart Connected Lighting group at JOANNEUM RESEARCH Forschungsges.mbH, in Pinkafeld, Austria. His research focuses on Visible Light Sensing, Visible Light Positioning, sensors, sensor fusion and algorithm design.
