It transparently provides multiple cursors, one for each mouse. To handle \n orientation issues for tabletop displays (i.e., people seated across from one another), programmers \n can specify a participant's seating angle, which automatically rotates the cursor and translates input \n coordinates so the mouse behaves correctly. It also provides an SDG-aware widget class layer that \n significantly eases how programmers create novel graphical components that recognize and \n respond to multiple inputs. The video shows examples of how simple SDG applications can be \n built, and demonstrates several applications and widgets that were developed by ourselves and \n others in a relatively short amount of time.","bbox":{"left":0.108823,"top":0.391955,"width":0.7768769999999999,"height":0.23101500000000003}}],"images_bbox":[],"images_bbox_not_text_overlap":[]}
