Abstract: A display system includes a housing, a display device provided at the housing and exposed from a first side of the housing, a first interface provided at a second side of the housing different from the first side of the housing, and configured to transmit data, and an interaction device. The interaction device includes an interaction member configured to respond to and/or generate interaction data, and a second interface configured to be detachably connected to the first interface and transmit the data. After the second interface is connected to the first interface, the interaction device is configured to maintain a positional relationship with the display device.

Abstract: A support device. The support device includes a seat for contacting a bearing surface when the support device is placed on the bearing surface and a support body having a first end and a second opposite end for supporting an output device, the first end being connected to the seat, the second end being connected to the output device, the connected output device facing a first direction. The support body includes a first receiving space, and the first receiving space is configured to accommodate at least a part of a processing device. The support body includes at least one opening facing a second direction, at least a part of an interaction part of the processing device to be placed in the first receiving space is exposed through the opening, and the second direction is different from an opposite direction of the first direction.
