Individual differences in wrist posture vary when using computer mice and trackballs. Some users may face injury risks from prolonged use, with trackballs potentially reducing ulnar deviation but increasing wrist extension.

Area of Science:

  • Ergonomics
  • Human-Computer Interaction
  • Occupational Health

Background:

  • Prolonged use of pointing devices can lead to musculoskeletal discomfort and injury.
  • Specific postures, such as wrist extension and ulnar deviation, are associated with increased risk.

Purpose of the Study:

  • To investigate individual variations in wrist postures during the use of a mouse versus a trackball.
  • To identify potential risk factors associated with different pointing device 사용.

Main Methods:

  • A multiple case study design involving twelve participants.
  • Measurement of wrist flexion/extension and radial/ulnar deviation.
  • Standardized tasks simulating horizontal and vertical cursor movements.

Main Results:

Related Experiment Videos

  • Both mouse and trackball use resulted in exposure to extreme wrist postures.
  • Trackball use was associated with reduced ulnar deviation but increased wrist extension.
  • Significant individual differences in adopted wrist postures were observed.

Conclusions:

  • Certain users may be at higher risk of injury due to prolonged pointing device use.
  • Trackballs may mitigate risks associated with ulnar deviation but could exacerbate wrist extension in some individuals.
  • Understanding individual differences is crucial for ergonomic device selection and injury prevention.
