The invention relates to a virtual two-dimensional positioning module for an input device, in particular to a two-dimensional positioning using an IR laser light, at least a linear line sensor and a controller. Module.

The present invention relates to a virtual two-dimensional positioning module for an input device, wherein the input device refers to a transmission interface that can be driven by an input device to drive a matching application device, such as a user interface (referred to as a user interface). User interface) or human interface (HID, Human Interface Device) and other transmission interfaces. At present, the system architecture of a user interface or its application field can be roughly divided into two different types of touch and remote control.

The touch user interface includes a variety of different touch systems and methods such as Resistive, Capacitive, Surface Acoustic Wave (SAW), Infrared (IR), Optical (optical imaging), etc., which is directly touched on a touch display screen by a control member such as a finger or a stylus to control various functions of the display, such as clicking a job, switching a screen, zooming in/out, or touching Control games, etc., to replace the commonly used push-button or rocker control.

Among them, the optical touch system includes US 2009/0200453, US 7, 538, 759, US 7,692, 625, US 7,629, 967, etc., which are provided with a light source such as an LED light source on a side or four corners of a panel (display screen) for forming a light curtain on the panel, and A reflective strip or a light absorbing strip and a sensor with at least two sensing directions interlaced are disposed on the edge of the peripheral edge of the frame. When a control member such as a finger or a stylus is touched on the panel, the control member can be The light curtain is caused to scatter or block the light. At this time, at least two directions of the control member can be sensed by the at least two sensors through the reflection of the reflective strip or the absorption of the light absorption strip. The relative position of the processor is used to obtain the actual position coordinates of the control member on the panel, thereby achieving the function of using the optical touch system; in other words, the conventional optical touch system utilizes the At least two sensing functions of the camera and computing functions of the processor can generate a two-dimensional positioning function on the panel. However, conventional optical touch systems mostly use LED light sources, and LED light is not a high coherent light source, and is susceptible to external stray light, so it cannot effectively improve the sensitivity of touch, and the entire system architecture. It must be used with reflective strips or light-absorbing strips, so that there are restrictions on the frame, and it is easy to have dust and dirt adhering to the frame and affecting the touch function. Therefore, the system architecture is complicated, the cost is relatively increased, and the system stability is also affected. Relatively reducing the use efficiency, the technology of the two-dimensional positioning function of the conventional optical touch system cannot be directly applied and is used as the two-dimensional positioning module of the input device of the present invention.

In addition, in the related art field of using a projection technique to form a virtual input device such as a virtual keyboard, there are quite a few prior art, including: US 5,168,531, US 5,198,877, US 5,448,263, US 5,617,312 US 5, 627, 565, US 5, 767, 842, US 5, 798, 519, US 5, 933, 132, US 5, 969, 698, US 6, 037, 882, US 6, 043, 805, US 6, 104, 387, US 6, 115, 128, US 6, 229, 913, US 6, 252, 598, US 6,266,048, US 6,281,878, US 6,323,942, US 6,424,334, US 6,512,838, US 6,522,312, US 6,614,422, US 6,690,354, US 6,690,618, US 6,710,770, US 7,006,236, US 7,050,177, US 7, US Pat. No. 6,614,422, US Pat. System and method for entering data. However, the above prior art still has the disadvantages of complicated system architecture and miniaturization in practical applications, so that it is not conducive to the application of various input devices and affects the use efficiency.

In addition, the remote user interface utilizes a feature object (control member) such as a gesture or a part of the human body to cause a change in relative position and motion in a three-dimensional space of X, Y, and Z to control the display by remote control. The function of the feature object (control member) is not directly touched on the display screen. The prior art of the current remote control user interface includes: WO 03/071410, US 7,348,963, US 7,433,024, US 6,560,019, US 2008/0240502, US 2008/0106746, US 2009/0185274, US 2009/0096783, US 2009/0034649, US 2009/0185274, US 2009/0183125, US 2010/0020078, etc., and TW 200847061, TW 201033938, TW 201003564, TW 201010424, TW 201112161, and the like. Although the remote control user interface has a three-dimensional positioning function, the following problems may occur in the application: (1) The conventional remote control user interface generally uses a two-image capture camera to capture the feature object ( The relative position of the control member in the three-dimensional space (XYZ) and/or the image of the motion change are available for coordinate positioning calculation (ie, having a three-dimensional positioning function), and since an image capturing camera is provided, when applied, There is a security risk of being stolen; (2) the coordinate positioning operation causes an increase in the amount of computation of the controller and the complexity of the software; (3) more related components, no The method effectively reduces the manufactured product; (4) the constituent elements used, such as the two image capturing camera or the infrared light source, are arranged to face a three-dimensional space (XYZ) having a large effective range, resulting in the constituent elements The relative height of the set position is high, so it is difficult or impossible to miniaturize. Therefore, the system architecture of the conventional remote user interface cannot or is not conducive to applications directly imported into various input devices, and is particularly disadvantageous for input devices having two-dimensional positioning functions or applications thereof, such as virtual keyboards constructed with other projection devices. , virtual switches, access control systems, etc.
