Give the heart a beat

The muscles of the heart contract and relax in a fixed rhythm and pattern to promote blood flow throughout the body, delivering nutrients such as oxygen to various parts of the body. This rhythmic beat ensures the continuous circulation of blood. The number of heartbeats per minute is called heart rate, and adults typically have a heart rate of 60-100 beats per minute. Heart rate is influenced by various factors such as age, mood, diet, health status, and exercise.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The heartbeat is a symbol of life, serving as the "center" of the body that pumps blood. Under normal circumstances, it beats rhythmically like a clock. Normally in a clear and quiet state, infants have a heart rate of 120-140 beats per minute, young children 90-100 beats per minute, school-age children 80-90 beats per minute, and adults 70-80 beats per minute. But heart rate is not constant, it is related to factors such as emotions, diet, illness, and exercise. Generally speaking, at rest, 60-100 beats per minute are within the normal range.
