Abstract: The present invention discloses an automatic particle measurement cart and an automatic particle measurement system for clean room and a measurement method thereof. The automatic measurement cart includes an automatic piloting device, which guides the cart to move along a pre-set path. The automatic piloting device includes a reading head, which recognizes the pres-set detective path and detects multiple pre-set measurement points. The cart moves along the detective path. A measurement device measures particles at the measurement points. A data processing device receives particle data measured by the measurement device and provides output according to a pre-set rule. With the above manner, the present invention can automatically measure clean room particles at a given site so as to reduce human labor involved and improve the preciseness of measurement result.

Abstract: An interactive system includes a display device and an interactive device. The display device includes a display module for displaying an image thereon, a S processor module and a transceiver. The interactive device includes an image capturing unit, a control unit, and a signal transceiving unit configured to communicate with the transceiver. The image capturing unit is operable to capture at least a part of the image displayed on the display module. The control unit is operable to transmit information of the captured part of the image to the transceiver via the signal transceiving unit. The processor module is operable to determine location of the interactive device relative to the image displayed on the display module based on the information of the part of the image received by the transceiver.
