Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     The present application claims priority to U.S. Provisional Patent Application No. 62/375,566 filed on Aug. 16, 2016, entitled “TELEOPERATED ELECTRONIC DEVICE HOLDER” the entire disclosure of which is incorporated by reference herein. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of Invention 
     The present invention relates to a holder for electronic devices with movements that may be controlled remotely for video-telephony. 
     2. Description of Related Art 
     Since its first commercial use in the late 1930s, video-telephony has sought to create an immersive experience to simulate face-to-face conversation across great distances. In the early 1970s, AT&amp;T&#39;s “Picturephone” allowed analog video and audio transmission over short distances. At the time, the Picturephone was thought of as a revolutionary system of communication when both parties could not meet face-to-face. 
     Video-telephony allows for better communication as users are able see one another&#39;s facial expressions, body language, hand gestures, and in some cases sign language. Modern advancements in video-telephony have popularized videoconferencing. In which, business meetings can be held among multiple parties from multiple locations around the world. Simultaneous two-way video and audio transmissions allow for a live collaboration in business, school, and personal settings to be carried out as if the parties were in the same room. 
     In more complex situations, the need to remotely operate a videotelephone device may be required. Military drones and NASA rovers are two examples in which a user can remotely control, or teleoperate, a device capable of video-telephony to achieve a first person view over a great distance. Teleoperation can allow remotely controlled investigation and intervention in circumstances which can be considered dangerous or impossible for a person to be placed in. Although convenient, most teleoperated devices are extremely complex and costly. 
     Present day video-telephony is readily accessible to almost anyone with a mobile device capable of accessing the internet. Mobile electronic devices can be used in conjunction with applications, which access the cameras and microphones of the device, to allow two or more parties to engage in a video-telephone conversation using wireless internet connections. 
     Currently, engaging in a modern video-telephone conversation requires the user to hold the device, use a fixed camera, or fix the device to a mount. This limits the perspective of the other party to the angle the user holds the camera, or to the angle that the camera is fixed at. In turn, neither party has control of the perspective being displayed on his or her screen, as it is determined by the other user or mounted angle of the camera. 
     Based on the foregoing, there is a need in the art for a means to remotely control the perspective of a device being used in during a video-telephony communication by a user on the other end of the communication. 
     SUMMARY OF THE INVENTION 
     The present invention is a teleoperated device holder. In the preferred embodiment, the holder is provided with a base. The base is to remain stationary during operation, and is placed on a stable surface. A first motor is provided with a drive shaft, which attaches to the base of the holder. In the preferred embodiment, the body of the first motor is secured onto the floor. In the preferred embodiment, the arrangement allows the floor rotates about the center of base, when the first motor is activated. 
     In the preferred embodiment of the present invention, the teleoperated device holder is further provided with a second motor.

     In a preferred embodiment, the top motor  9 , and the bottom motor  1  work independently. But together they allow for the mount  7  to be adjusted to up, down, left, or right. In an embodiment, the motors may be activated at in a one-at-a-time fashion, allowing for only one directional movement at a time. In another embodiment, both motors may be activated at the same time allowing for a diagonal or in-between directional movement. 
     In reference to  FIG. 4 , a flowchart is shown depicting the operation of the teleoperated device holder. The operation of the device holder begins when a transmitting user, herein referred to as the transmitter, creates an input signal  17  from their local device. The input signal  17  may be a mouse movement, keyboard action, trackpad movement, or signals generated by other software or hardware installed on the local device. The local device is provided with a video source  18 , such as an integrated video camera. In the preferred embodiment, the video source  18  is combined with input signal  17  to create an encoded video  19 . 
     In the preferred embodiment, the user then chooses the encoded video  19  as the video source for their preferred video chat application  20 . The encoded video  19  is then received by a receiving user, herein referred to as the receiver, on their device via the video chat application  20 . The receiver&#39;s device is mounted to the teleoperated device holder and displays the encoded video. In the preferred embodiment, the sensor array  2  picks up the input signals from the encoded video and transmits them to the PCB  5  of the teleoperated device holder. The PCB  5  then decodes the signals received by the sensors  2  and transmits the appropriate signal to the top motor  9  and bottom motor  1  to move the device as directed by the input signal  17  controlled by the transmitter. 
     In reference to  FIG. 5 , a flowchart is shown to depict the operation of the teleoperated device holder, wherein the device holder is remotely controlled by a nearby device. In the embodiment, input data  21  is received by the nearby device, human input, or data received from another device. The data is processed by the nearby device and emitted towards the device holder. The signal emitted by the device may be an image, sound, or vibrational signal. The emitted signal is then captured by the sensors  10  of the device holder, transmitted to the PCB  5 , and sent to the top motor  9  and bottom motor to move the receiver&#39;s device as desired. 
     In an embodiment in which a sound sensor is used, the operation process is the same, however the encoded video emits a sound to be picked up by the sensors  10  instead of a light. 
     In reference to  FIG. 6 , a flowchart is shown to depict the operation of the face tracking feature, according to an embodiment of the present invention. In the embodiment, a provided application will recognize a receiver&#39;s face within the image captured by the device camera, as is known in the art. As the receiver&#39;s face moves towards the perimeter of the image, the application will generate an encoded video to be received by the sensors  10 . The sensors  10  will transmit the encoded signal to the PCB  5 , which will signal the motors to move the device in the holder, such that the receiver&#39;s face is placed into the center of the image. 
     The invention has been described herein using specific embodiments for the purposes of illustration only. It will be readily apparent to one of ordinary skill in the art, however, that the principles of the invention can be embodied in other ways. Therefore, the invention should not be regarded as being limited in scope to the specific embodiments disclosed herein, but instead as being fully commensurate in scope with the following claims.
