Lin, Giovanni (author)Augmented Reality has the potential to expand our interaction with our surrounding environment. A potential solution to improve this interactability is Visible Light Communication through blinking Light Emitting Diodes (LEDs). Data is encoded and then transmitted by blinking the LED, a smart-phone camera is then pointed at the LED to decode the...bachelor thesis 2022

van Ingen, Bart (author)Pedestrian indoor localization is a problem yet to have a solution that is as generally accepted as the Global Positioning System is for outdoor localization. An infrastructure-independent option is to leverage the data from Inertial Measurement Unit (IMU) sensors to determine position. An advantage of this approach is that these sensors are...master thesis 2020
