A digitizer system includes a substrate with indicia having photoluminescent features that uniquely define local areas of the substrate. A sensor device, such as a stylus, may sense radiation emitted from the features, and a controller may determine therefrom the location of the stylus relative to the substrate.

An optical navigation device, comprising: an optical sensor, configured to sense optical data; and a processing circuit, configured to compute motions of the optical navigation device based on the optical data, and configured to output the motions, wherein a first CPI is set to the processing circuit. The processing circuit receives a calibration command to calibrate the first CPI to a second CPI, wherein the second CPI is computed via following steps: (a) computing a real CPI corresponding to times of motions output by the processing circuit during a time interval that a relative displacement between the optical navigation device and a surface reaches a first predetermined distance; (b) computing a ratio between the real CPI and the first CPI or a difference between the real CPI and the first CPI; and (c) generating the second CPI based on the ratio or the difference.

An image processing method capable of detecting noise includes adjusting a lighting unit to acquire an over-exposure image, comparing each pixel of the over-exposure image with at least one threshold value, labeling a pixel of the over-exposure image as the noise while bright intensity of the pixel is lower than the threshold value, and removing the noise to execute a displacement detecting calculation.

A mobile device input device connected to a mobile device, the mobile device input device including a main body to be worn by a user, a control unit running a program thereon and disposed within at least a portion of the main body to at least one operation of the mobile device, and a laser sensor disposed on at least a portion of the main body to emit a laser beam away from a surface of the main body to track a position of the main body.

The present invention relates to a mouse for a computer, which is a computer input device. The mouse has an upper case with a vertical cushioning function against force imposed on the mouse, and thus can operate smoothly. The present invention provides a cushioning function to a mouse, thereby eliminating fatigue and muscle pain of the wrist and fingers even when a user uses the mouse for a long time. The mouse is manufactured by assembling an upper case and a lower case, and is configured such that a protrusion box which protrudes upwards is formed on the lower case, a boss is fixed on the lower side of the upper case and penetrates the protrusion box, thereby being joined with the same, and a spring which is supported by the protrusion box is inserted into the boss from the outside while the lower side of the boss can be prevented from being separated from the protrusion box.

In an approach to pointer positioning, a computing device receives an instruction to enter a Move Mode. The computing device magnifies, in Move Mode, screen content to generate a virtual display. The computing device displays a first portion of the virtual display and a fixed pointer on the virtual display. The computing device receives physical movement data. The computing device analyzes the physical movement data. The computing device displays a second portion of the virtual display based on the analyzed physical movement data. The computing device receives an instruction to leave Move Mode. The computing device deactivates Move Mode.

Aspects of the present invention relate to external user interfaces used in connection with head worn computers (HWC).

Systems and methods are disclosed for a smart mouse that may include transmitting, by the mechanical switch of the smart mouse, a signal to a microcontroller unit of the smart mouse in response to a movement of the smart mouse caused by a user, the movement causing the mechanical switch to be in a closed position, the signal indicating that the mechanical switch is in the closed position; receiving, by the microcontroller unit, the signal indicating that the mechanical switch is in the closed position; and in response to receiving the signal: causing, by a power switch of the smart mouse, at least one battery of the smart mouse to provide power to an optical unit of the smart mouse, the provided power causing the optical unit to be in an on state, the on state of the optical unit causing the smart mouse to be electrically enabled for use.

In order to allow a worker to accurately and repeatedly mark an original plan on a working surface, the present disclosure provides a nonrestrictive drive-type marking system comprising a nonrestrictive drive-type marking device, the nonrestrictive drive-type marking system including an input unit configured to receive data of content to be marked; a marking unit configured to mark the content corresponding to the data on a working surface; a driving unit configured to allow at least a part of the nonrestrictive drive-type marking device comprising the marking unit to nonrestrictively move on the working surface; a position detecting unit configured to sense position information of the nonrestrictive drive-type marking device; and a control unit electrically connected to the input unit, the marking unit, the driving unit, and the position detecting unit, and configured to calculate a current position of the at least the part of the nonrestrictive drive-type marking device comprising the marking unit by comparing the position information with the data, to compare the current position with the data, and if the current position does not match with the data and a degree of mismatch thereof is within a preset range, to move at least a part of the marking unit, and to control the nonrestrictive drive-type marking device to mark the content corresponding to the data on the working surface while the nonrestrictive drive-type marking device moves.

A mouse as an example of an electronic equipment can be used in medical settings and includes a housing that can be gripped by a hand, a substrate which is arranged in a space in the housing and on which an electronic circuit component for calculating a state of the mouse is mounted, and an optical element (lens) which is arranged in a part of a bottom portion (housing bottom portion) of the housing and through which image light from outside enters. The optical element and the electronic circuit component are connected by a transmission unit capable of transmitting the image light. The substrate is arranged so as to be separated from the housing bottom portion upward in a Z direction by a distance between a lower surface of the housing bottom portion and a lower surface of the electronic circuit component in the Z direction and/or by a distance between an upper surface of the housing bottom portion and a lower surface of the substrate in the Z direction. For example, an optical fiber is used as the transmission unit.
