This monday, during the VLCS’17 Workshop collocated with Mobicom at Snowbird, USA, Ander Galisteo, Domenico Giustiniano (IMDEA Networks Institute, Madrid), and Hongjia Wu, Qing Wang, Diego Juara and Marco Zuniga (Delft University of Technology), unveiled the new version of the open-source VLC prototyping plateform OpenVLC presenting a poster.
They improve the plateform data-rate and performance thanks to new hardware (better photodetector, high-power LED circuit) and leveraging the Beaglebone Black Programmable Real-time Unit (PRU) to provide better timing and clock accuracy.
At Ubicomp’17, Tianxing Li form Dartmouth College introduce Aili, a table lamp able to reconstruct a 3D hand skeleton in real time, requiring neither cameras nor on-body sensing devices thanks to visible light.
Aili consists of an LED panel in a lampshade and a few low-cost photodiodes embedded in the lamp base. Aili reconstructs the 3D motion by sensing the panel light-beam obstruction by the hand.
This work shows original application of VLC in the field of sensing.
