[0035] figure 1is a schematic diagram showing the 3D air mouse according to the first embodiment. System 100 includes mouse 110, which is capable of periodically transmitting RF ultrasound trigger signals and simultaneously receiving ultrasound signals. Ultrasound transmitters 120 , 122 , 124 , 126 are placed around the television screen 115 . A cursor 140 is displayed on the television screen 115 . According to this embodiment, the position of the mouse 110 is used to determine where to display the cursor 140 . The movement and trajectory information of the air mouse is converted into the movement and trajectory of the screen cursor so as to remotely control the cursor.

[0036] In one non-limiting modification, a receive function is added to the ultrasound transmitters 120 , 122 , 124 , 126 arranged around the smart screen 115 and a reflect function is added to the air mouse 110 . In that way, by controlling different ultrasound transmitters to emit ultrasound signals at...

[0048] figure 2 is a schematic diagram showing a system 200 according to the second embodiment. System 200 includes a mouse 210 capable of periodically transmitting RF and ultrasonic signals. Receivers 220 , 222 , 224 , 226 are configured to receive ultrasound signals from mouse 210 and are placed around television screen 215 . The receivers 220, 222, 224, 226 are also configured to transmit the electrical signals converted from the ultrasound signals to a controller, eg, the television and / or set-top box. A cursor 240 is displayed on the television screen 215 . According to the present embodiment, the position of the mouse 210 is used to determine where to display the cursor 240 .

[0049] The 3D air mouse 210 provided in this embodiment completes the following steps:

[0050] 1) Three or more ultrasonic receivers 220, 222, 224, 226 are fixedly installed around the TV screen 215 and electrically connected with the TV. Upon receiving an ultrasound signal, the ultrasound ...

Abstract

An air mouse system is described. The air mouse is configured to periodically transmit RF signals in order to trigger a plurality of ultrasonic transmitters arranged on a television. The ultrasonic transmitters transmit ultrasonic signals when being triggered by the RF signals from the RF trigger. An ultrasonic receiver receives the ultrasonic signals. A processor calculates a location of the air mouse with respect to the ultrasonic transmitters based on time differences of the ultrasonic signals transmitted by the ultrasonic transmitters arriving at the ultrasonic receiver. A series of locations of the air mouse forms a motion trail of the air mouse and the air mouse transmits the motion trail to the television wirelessly. The motion trail is projected as a cursor trail on the television screen by the television, to control the cursor on the television screen by virtue of the motion of the air mouse.

Description

Background technique [0001] Various embodiments relate generally to smart television systems, methods, devices, and computer programs, and more particularly, to human-computer interaction interfaces and motion remote controls. [0002] This section is to provide background or context. The description may include concepts that could be pursued, but not necessarily previously conceived or pursued. Unless otherwise indicated, what is described in this section is not admitted to be prior art to the description and claims and is not admitted to be prior art by inclusion in this section. [0003] With the continuous improvement of TV network functions and the gradual transition to the era of smart TVs, new human-machine interfaces and remote controllers have been guided to continue to develop. [0004] The continued growth of services along with web functionality has brought more complexity to list selection, and traditional menus featuring up, down, left, right functions, and an ...
