Abstract: Implementations relate to a moveable display system. In some implementations, a control unit includes a first support and a second support coupled to the first support. The second support is linearly translatable along a first axis in a first degree of freedom with respect to the first support, and at least a portion of the second support is linearly translatable along a second axis in a second degree of freedom with respect to the first support. The control unit includes a display unit rotatably coupled to the second support. The display unit is rotatable about a third axis in a third degree of freedom with respect to the second support, and the display unit includes a display device.

Abstract: Implementations relate to a moveable display unit on a track. In some implementations, a control unit includes a support linkage including a first support coupled to a second support, a track member coupled to a distal portion of the second support, and a display unit coupled to the track member. The display unit includes a display device. The display unit is linearly translatable in first and second degrees of freedom provided by the support linkage. The display unit is rotatable, with respect to the second support, about a tilt axis in a third degree of freedom defined by the track member.

Abstract: A foot controller includes a stationary portion and a cradle member that can receive a foot of a user. The cradle member is moveable to of different positions along paths, such as a left position, a right position, a front position, or a back position. One or more paths have a left-right direction of the controller and at least one of the paths has a forward-back direction of the controller. Sensors sense the cradle member at a particular position and output sensor signals indicative of that position. A function provided by a system is activated based on the sensed position.

Abstract: Implementations relate to a foot controller. In some implementations, a controller includes a stationary portion and a cradle member configured to receive a foot of a user. The cradle member is moveable to a plurality of positions along paths, the positions including one or more of a left position, a right position, a front position, or a back position. One or more of the paths have a component direction along a left-right axis of the controller and one or more of the paths have a component direction along a forward-back axis of the controller. One or more sensors sense the cradle member at a particular position, output sensor signals indicative of the particular position, and cause activation of a selected function provided by a system based on the sensed particular position.
