Eye tracking? Wearable device that tracks eye movements

Tobii, a company that provides eye tracking research solutions, launched an eye tracking device called Tobii Glasses 2 earlier this year and opened for pre-sales, and the device is now officially shipped worldwide.

Eye tracking is a very valuable way of doing research. For example, when consumers are in front of the shelf, their eye movements can "point out" the items that they are most interested in. Through this device, enterprises can learn the consumer behavior of the tested consumers in real time, and use this as a basis to create a more dynamic shopping environment for them.

Tobii Glasses 2 weighs only 45 grams and looks no different from other sports glasses in appearance, which gives the testees maximum flexibility and less attention to the experiment itself.

This wearable device features a wide-angle 1080P scene camera and four sets of eye-moving cameras, all mounted in an ultra-thin frame, which not only provides the testee with a completely free field of view, but also allows researchers to The ultra-wide range (including the surrounding visual field environment) is used to track and analyze the "true and natural" eye movement of the test subject.

Tobii Glasses 2 has broad application prospects. In addition to retail in-store marketing, it can be used in research, sports, consumer technology, gaming, automotive, medical and other research fields.

KSNFJ is a factory ready-mix powder that has undergone strict quality control to facilitate on-site construction. It contains a selection of metallic mineral aggregate materials and specialty Portland cement, as well as special additives to promote construction performance. Specially made materials ensure gradation and free from impurities, which aggregate shows good conductivity and wear resistance.


KSNFJ for the need to improve the wear resistance, resistance of the concrete surface, in particular, sparks, antistatic areas. For example: flammable warehouse, chemical plants, petrochemical plants, dangerous products workshop, gas stations, liquefied gas stations, hangars, textiles, electronics, paper, printing and other long-term electrostatic regions.

Product Advantages:



1. To make the ground extremely hard, wear and impact resistance

2. With the concrete surface to form a monolithic bond

3. Fireworks conductive static

4. Anti-all kinds of oil, grease erosion

5. Easy to construct


Material properties:



Wear resistance: The KSNFJ-treated concrete floor exhibits at least three times more wear resistance than the untreated concrete floor.


Electrical properties: KSNFJ shows good electrical conductivity to dissipate static electricity. KSNFJ can be grounded in the traditional way with specific requirements. Due to the ductility of metallic materials in the ground so that the impact of metal collision with a high degree of fireworks.

Surface resistance: 1.0×105 ~1.0×108Ω

Compressive strength: Using the same amount of water as the actual construction, KSNFJ test block 28 days standard compressive strength of 90Mpa.

Storage: KSNFJ and Curing Agent intact packaging stored at room temperature and dry environment, the storage period of six months.

Health and Safety: The cement powder contained in KSNFJ will adversely affect the skin during normal use. When the product is mixed with dampness, the released alkali will damage the skin, irritate the eyes and respiratory system, avoid inhalation of its powder, and avoid skin and eye contact. Wear suitable gloves and eye protection. Once touched the skin, wash with water. Once you reach your eyes, immediately wash with plenty of water and seek medical treatment.
