Problems solved by technology

However, there is a problem that the traditional mouse industry has not answered, that is, what is the relationship between the movement vector and a specific SQUAL value, and how does this relationship further affect the positioning accuracy of the navigator? These are the traditional mouse industry failed to answer

[0313] The first embodiment represents a navigator using a single light source and its method of use, the navigator being able to extract a rotational motion vector from a generalized motion vector. Navigator like this, in figure 2 There are introductions in Figures A to E. The method of extracting the rotational motion (vector) from the generalized motion (vector) used by it is explained in the text of this embodiment, and when explained, it is also borrowed Figure 3A and 3B Graphical explanation.

[0314] let's see now Figure 3A , the figure shows three groups formed by tracked objects on the desktop, these three groups are: 301A, 301B, 301C, 301D; 302A, 302B, 302C, 302D; and 303A, 303B, 303C, 303D. For the convenience of explanation, the three groups (the tracked objects) are surrounded by dashed circles (Dashed circles), so the three groups can be regarded as composite point-objects (Composite point-objects) . To explain more clearly, these dots representing grou...

[0341] The second embodiment needs to refer to Figures 4A to 4E come to find out. Such as Figure 4E As shown, navigator 402 contains multiple light sources ( 401 , 405 , and 406 ) surrounded by an aperture 404 . Figure 4A The dashed rectangular block 407 shown above is an auxiliary control device of the navigator of the present invention, which can be used to start a function or do similar work. Under preferred implementation conditions, the plurality of light sources included in the present invention have different optical properties (eg, color, or more specifically, wavelength) from each other. The object to be tracked 408 is placed on the table and is in the area within the perimeter of the hole 404 . These light sources 401, 405, and 406 illuminate the tracked object 408, and the light reflected (from the tracked object 408) will hit the detector 403, and the detector 403 will have appropriate sensitivity to the characteristics of the above-mentioned light sources ( ...

[0349] In this embodiment, the hue (Color tone such as: CIE1931 Color Index or similar index) of the shadow cast by the object on the desktop to the desktop will be used to calculate the rotation vector. It should be noted that the second embodiment is different from the third embodiment in terms of design concept of components. In the second embodiment, we hope to remove the non-linear term in the motion vector by polychromatic light and color image detector. In fact, some non-linear items can be used to detect shadows or some special actions of objects, and the detection results can ultimately improve the performance of the components of the present invention.

[0350] Such as Figure 6A As shown, the basic structure of the components used in this embodiment ( Figure 6A Only the part showing the pore structure) is the same as the second embodiment (such as Figure 4A ) The basic structure of the components used is similar. Figure 6A A plurality of color light sources (...

Abstract

The inventon provides an optical mouse with a cursor rotating ability, an instrument, a portable detection device and a method thereof. The instrument at least comprises: a moving deivce, which is arranged on a position relative to a reference surface, wherein a plurality of traced articles are arranged on the referece surface; a hole; at least an optical detector; and at least a light source. The instrument utilizes at least an optical detector to generate an image frame, which is represented by an electronic pixel picture, a plurality of images representing the traced articles exist in the electronic pixel picture; the instrument can generate general movement vectors of the traced articles according to the changes of the picture; and the general movement vectors can be divided into a parallel movement part and a rotation movement part. The instrument can rapidly and precisely transmit the displacement vectors and rotation vectors of the related movement to a display screen of a computer or other display screens, and thus the movement of the cursor displayed in the computer or the display screen can be controlled.

Description

technical field [0001] The invention relates to a motion navigator (Motion navigation device), which can be used on a computer or other electronic equipment with a graphic display (Graphical display). Background technique [0002] A traditional optical mouse is usually moved on a surface, which can be the surface of a table or other surface; when operating, a traditional optical mouse can calculate and provide a vector for the movement of the cursor required by a computer connected to it (Translational motion vector; for example, displacement Δx, Δy; or based on needs, the vector is a certain speed value), this movement vector is related to the relative position of the mouse and the surface. By these displacement vectors, a computer or an instrument with pattern display capability can move a cursor, or move an object (Objects) displayed on other screens (also referred to as images in the present invention), Even change the state of the software object (Object) (note that in...
