Abstract: The present invention relates to a method and device for diagnosing a defect of a collaborative robot, the method comprising the steps in which: an electronic device generates a sensing data structure for managing sensing data collected from at least one collaborative robot; the electronic device generates an operation data structure for managing operation data associated with the operation of the collaborate robot; the electronic device generates a malfunction data structure for managing malfunction data of a point in which the severity of the operation equals to or is higher than a threshold; and the electronic device stores data collected from the at least one collaborative robot in accordance with the structures. Application to other embodiments is also possible.

Abstract: Disclosed are a method and an apparatus for recognizing a key input from a virtual keyboard according to one embodiment of the present invention. The method for recognizing a key input from a virtual keyboard according to one embodiment of the present invention is a method for recognizing a key input from a virtual keyboard using at least one camera, e.g. two cameras or one 3D camera, and includes the steps of: tracking a user tool when the actuation of the user tool for a key input on the virtual keyboard is detected using the camera, and continuing the tracking until the vertical coordinate of the position of the user tool is less than or equal to a predetermined vertical threshold value; and determining that a key input has been carried out at the last tracked horizontal position of the user tool.
