Microsoft's new generation of mouse technology using Blu ray LED lighting

A computer mouse is always one of the user interface is very important, since the early mouse prototype at the end of 1960s, the mouse has undergone a long period of time, technological innovation change rapidly also makes mouse performance improvement. Microsoft (Microsoft), the latest launch of an optical mouse positioning and usability of the mouse to open a new window of technology.

The role of the mouse pivotal, cheap, and intuitive easy to use. At the same time, as with any existing technology, the mouse continues to evolve in the process of technology development. Microsoft Corp recently released BlueTrack series of mouse, to promote the field of lighting and image processing technology innovation. As the name suggests, BlueTrack uses the blue light to replace the traditional optical mouse generally issued by red light or laser light.

All optical mice have the same operating conditions. The surface of an optical mouse is illuminated by a LED - usually using a number of optical components to convert a single point source into a larger range of light. Then, the light on the surface of the mouse pad is guided by second curved surfaces which focus the reflected light of the illumination area on the lower resolution image sensor. No matter how low pixel, image processing can be through the precise characteristics of the mouse pad surface to read ", and to determine the relative direction of movement of the imaging to identify action. Through the observation of the environment, the mouse can identify its moving route.

However, it is well known that the surface of the mouse used to glide is quite important to the mouse. If there is a lack of traceable surface changes or patterns, the mouse may be able to move but the cursor is unable to do so. The solution of Microsoft Corp using photoelectric technology and patented laser non blue light source to replace the traditional red / infrared LED (usually called laser LED), expect to be able to effectively improve the mouse sliding surface available range.

This Blu ray technology is said to provide a higher contrast image, to some extent, similar to ultraviolet light, can make the details of the hidden one (imagine the scene of the crime scene). Microsoft Corp also uses the LED light source to provide a more uniform flux in the lighting area.

After folding remove all hidden screws, the Microsoft Corp Blue-Track mouse can be used to track the list of no doubt, LED is a simple mold by optical positioning guide assembly, the sealing material can achieve translucent emulsion capsule transmission characteristics. Several other blue LED around the mouse around, but its effect is only used for decoration and lighting products, or in the mouse shell formed around like a halo effect (halo effect) blue halo.

The other half of the optical device is a CMOS image sensor and image processor ASIC, is designed and manufactured by Microsoft Corp. The built in window of the sensor package enables the reflected image to reach the 24 x 24 pixel array of the component (with respect to the imaging standards, the resolution is still low, but it is more than adequate). Because the component has the functions of control, processing and imaging (all of which are powered by two AA batteries), the adoption of the small pixel array can reduce the power consumption, and can improve the processing speed of the frame under the condition of specific power consumption. The ASIC uses Atmel 32Kb (4KB) EEPROM to store embedded program code.

Optical technology introduced in roller key function of another mouse design for mold "roller rolling control" to form an optical chopper, roller motion sensing and applied to LED/ phototransistor. Other mouse input functions are also very rich, but like the usual left / right mouse button activated surface mount switch, as well as pressing and tilting the wheel to achieve special functions such as the same. Because of the lack of other logic in the mouse, the controller's switch, roller chopper encoding and U** communications are all on Microsoft's main ASIC. The design uses the most popular wireless link between the mouse and the host computer without having to use a chaotic connection. On the host side, a small U** dongle is used to receive all the mobile data from the mouse, but interestingly, the chip solution does not meet the U** industry alliance established Wireless U** standard. Nordic Semiconductor provides proprietary 2.4GHz transceivers at both ends of the link (but the links are somewhat different). The mouse uses Nordic's NRF24L01 components, while the U** part uses the NRF24LU1 component. The transceiver is built in a single chip EEPROM, thus eliminating the need for additional memory.

Most of the electronic components of the mouse are concentrated on two large printed circuit boards, and the rollers and switches are located on the expansion board connected with the flexible circuit. A total of about twelve blocks within the mould slice, small screws will be used for all mold components together.

It is said that almost any surface can slide Microsoft BlueTrack to replace the traditional LED optical mouse red light or laser light.

Now, the computer mouse has been born for forty years, it has been an important choice for most computer users to locate tools, mouse technology has been evolving. Optical technology to replace the past very easy mechanical roller with dust, but also further improve the illumination and image processing, the user can use the mouse more accurate positioning, at the same time, with the so-called almost what surface can slide BlueTrack, mouse for sliding surface material requirements are not so harsh.
