It is Beyond the Optical, Laser and Blue-ray…

It has been more than half a century ago, that Dr. Douglas Englebart invented the first mouse back in 1968. The mouse tracking technology then initiated with mechanical decoding, and was generationally developed to optical, laser and Blue-ray. All systems are now coexisting in today’s market, yet none of them is able to completely resolve the adaptability issue. Why do all mice still require a mouse pad to function properly? This question puzzles most mouse fans daily. Wouldn’t it be great if there was a new and superior technology to resolve this adaptability issue and liberate us from mouse pads once and for all?
The Principle and Imperfections of the 1st Generation Mouse Engines
The sensor of an optical mouse works like a mini camcorder. It utilizes basic photography by applying a slanted incident LED light on the surface. The sensor captures continuous images and differentiates the image features. This data is used for calculating the vector values and determines the direction and speed of cursor movement. It uses scattered reflective light to illuminate the objective, see the illustration above as shown.
Simply to say, if you want to move the cursor on a very glossy or over a rough surface, you will find that the cursor is sluggish or doesn’t even move at all.
Traditional Mouse Adaptability Analysis
While working on glass, the LED light will pass through and bounce off the transparent glass surface. In these situations, the sensor is not able to find enough shadow points. Consequently the cursor is sluggish or almost dead.
While the regular mouse working on the multi-color or plaid pattern surfaces (e.g., a mouse pad), the generated shadow points/images change constantly and disorderly. The sensor is unable to track the motion precisely and leads the cursor to jump or lag problems. Therefore, it much relies upon a good quality mouse pad so as to improve such discrepancies.
Conclusions. Regardless of the use of regular optical or laser, all of mice have cursor control problems due to the slanted light, especially on surfaces like glass, marble, textiles, fur, etc. After our analysis and experiments, it is apparent that the surface adaptability of these mice is far from perfect
A groundbreaking revolution of V-Track
V-Track utilizes vertical incident light instead of the regular slanted light. The LED light is heavily reinforced and goes deeply into each point of the surface. The sensor then always captures clear images, which leads to ideal final vector values and perfect cursor direction and speed. It resolves the adaptability problems of traditional optical mice that are unable to work properly on many critical surfaces.
The innovative new A4 Tech V-Track technology resolves all adaptability problems! No more sluggish or immovable cursors when working on glossy, uneven or multi-color surfaces. V-Track applies a shorter light path and offers highly efficient power saving. It is this legend of new tracking technology that transforms the entire world in your mouse pad!
The problem of slanted light on uneven surfaces
Due to the slanted light, the regular optical or Laser sensor can not exactly capture the generated images when the sensor height increases. This is the reason why regular optical or Laser mice experience problems when used on uneven surfaces, like furs, carpets, etc.
Regular Sensor
V-Track Sensor
Instead of traditional slanted light, the V-Track uses vertical reinforced light which goes deep into the structures of surfaces. The sensor always exactly captures the images regardless of the irregularly increasing of the sensor height. The cursor control is very precise on all uneven surfaces.
Throw away your mouse pad! V-Track works everywhere
V-Track is the groundbreaking technology that utilizes vertical incident light instead of the regular slanted light. It works perfectly on most materials. With V-Track technology, the mouse cursor control is so precise that it works on any surface; it is the first mouse that really makes all mouse pads obsolete!
