Holding an arm outstretched for long periods of time to operate a vertical screen leads to 'gorilla arm' syndrome, with fatigue in the shoulder and arm. Constantly looking at a low-positioned mobile device causes 'text neck,' a significant strain on the cervical vertebrae. Correct, neutral posture is essential to avoid these symptoms.
Continuous tapping, swiping and typing on a flat, non-tactile surface is a major cause of RSI. Without the physical feedback of keys, users tend to apply more force than necessary. These repeated, small movements strain the tendons and muscles in the fingers, hands and wrists, which can lead to pain and inflammation.
Smartphones and tablets are often held in the hand and viewed at an unfavorable angle. This leads not only to 'text neck,' but also to tension in the hands and wrists from clenching the device. The small screen size can also lead to inaccurate and tense finger movements, further increasing ergonomic risks.
Touchscreens on desktops or stationary kiosks, which are often placed vertically, are not designed for prolonged interaction. Compared to a traditional setup with a mouse and keyboard, their operation requires an unnatural arm movement. For intensive use, such a setup is ergonomically inferior and can quickly lead to physical complaints.
Modern touchscreens lack the physical response of traditional buttons or keys. This lack of feedback often causes users to press harder than necessary to register an action. This excessive effort contributes to muscle fatigue and increases the risk of overuse injuries in the fingers and hands with frequent use.
This phenomenon describes the pain and fatigue in the shoulder and arm caused by holding the arm up for long periods of time to operate a vertical touchscreen. The human body is not built for this position, so the weight of the arm overloads the muscles. This problem occurs especially with large, fixed screens such as kiosks or smart boards.
‘Text neck’ is the term for the pain and damage to the neck caused by prolonged looking down at the screen of a mobile device. This hunched posture puts enormous pressure on the cervical vertebrae, which can lead to chronic pain, stiffness and, in the long run, even permanent postural problems.
To reduce risk, regular breaks and alternating postures are recommended. Using stands to place devices at eye level is crucial. For prolonged typing, external keyboards are a better option. Alternative input methods such as a stylus or voice controls can also significantly ease the strain.
