Abstract: Projection and camera systems may employ a joint locking mechanism that may enable a user to reposition or move structures (arms, lenses, etc.) that are otherwise locked in position. The joint locking mechanism may include a touch-activated presence detector to sense a presence of an extremity of a user. In response to the presence detector sensing the presence, an actuator may unlock a joint or structure to enable movement of the joint or structure while the presence detector continues to sense the presence. In response to a detection of an absence of the extremity, the actuator may return to a locked state to prevent further movement of the joint or structure.
