HUAWEI WATCH 4 Sport

AMOLED, or Active Matrix Organic Light-Emitting Diode, belongs to the OLED family of display technologies. This is the most advanced display technology on the market. Compared with competing technologies, it boasts faster response times, lower energy consumption, and sharper colours. You can also enjoy perfect black colour reproduction, which results in better readability in direct sunlight. AMOLED displays also offer wide viewing angles, which in the case of IPS displays reach almost 180 degrees. However, the disadvantage of AMOLED technology is its higher price and shorter lifespan.

A barometer is a sensor in a smartwatch that measures atmospheric pressure. It is used for weather forecasting, determining altitude and assisting in navigation. Its ability to provide data on pressure changes is crucial for outdoor activities such as hiking or climbing, where it can help in making safe decisions.

Galileo is Europe's global satellite navigation system that provides precise position and time information. The integration of Galileo into smartwatches improves location accuracy, which is advantageous for applications requiring accurate geolocation data such as maps, fitness and outdoor activity tracking.

Glonass is a Russian global navigation satellite system that works in parallel with the US GPS system. The use of Glonass in smartwatches is particularly advantageous for outdoor activities such as running, hiking, cycling or any other activity where tracking route, speed and distance traveled with a high level of accuracy is important.

An accelerometer is a sensor that measures and monitors changes in the speed of motion. In smartwatches, it is used to track physical activity such as step count, running, cycling and to recognize different types of movement. This sensor is the basis for fitness and health applications.

A gyroscope is a sensor that measures or maintains orientation and angular velocity. It is used to detect and track motion, changes in orientation and rotation of equipment. In a smartwatch, the gyroscope works with other sensors such as the accelerometer, which measures and tracks changes in the user's movement speed.

Accessibility for people with disabilities includes a range of features and settings in the smartwatch that make it easier to use for people with different types of disabilities, such as visual, hearing or physical disabilities. These features may include larger fonts, voice control or vibrating alerts.

The smartwatch's fall detection can detect if the wearer falls and automatically call for help, either by sending an alert to preset contacts (such as family members, friends or caregivers) or by initiating an emergency call. This feature is essential, for example, for the elderly.
