BumpMarker: a 3D-printed Tangible Marker for Simultaneous Tagging, Tracking, and Weight Measurement


BumpMarker is a 3D-printed tangible marker which accomplishes simultaneous tagging, position tracking and weight monitoring. A BumpMarker can be recognized on a high-resolution matrix pressure sensor sheet with its distinctive bottom pattern. The marker is designed by examining the physical constraints of the pressure map capturing process. A BumpMarker system can notice the position and weight change of containers without using a weigh scale.
