VoxelSensors is a deep-tech Brussels-based startup developing spatial and empathic computing solutions. We developed a unique sensor architecture called Single Photon Active Event Sensors, which enable low power spatial sensing modules and low power eye tracking modules. VoxelSensors adresses the need for low power contextual information on wearable consumer platoforms such as smartglasses, AR glasses and XR headsets. Our activities span from sensor and sensing module design, to the development of edge perception solutions extracting cognitive state, intention, attention vectors and much more, using state-of-the-art ML approaches.
