The presentation of the given keynote can be downloaded here.


Visible Light Sensing (VLS) in the most general meaning describes an approach that utilizes light received at a photosensitive device to generate information. Due to ongoing improvements in the fields of LED lighting and associated photosensitive devices as well as peripheral electronics such as amplifiers, filters etc. VLS has gained a lot of momentum to enable low-cost/low complex solutions for various applications ranging from occupancy detection to the monitoring of industrial machines.  

On the basis of concrete implementations of VLS, the main principles will be discussed as well as the major advantages compared to other technological approaches will be reviewed including also current limitations. Based on obtained results the future possibilities, especially towards integrating VLS into a broader network in the context of IoT will be 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.
