Summary
This study assessed non-keyboard input devices (NKIDs) for health and safety professionals. Standard mice, particularly the 2-button design, were found to be the most user-friendly and comfortable NKID option.
Area of Science:
- Human-Computer Interaction
- Ergonomics
- Occupational Health
Background:
- Non-keyboard input devices (NKIDs) are crucial for computer operation.
- Evaluating NKID design factors is essential for user performance and comfort.
- Previous research on NKID usability is fragmented.
Purpose of the Study:
- To identify key design factors for effective non-keyboard input devices.
- To assess the performance, operation, and comfort of various NKIDs.
- To develop practical tools for NKID selection and evaluation.
Main Methods:
- User-centered assessment of eight NKIDs (mice, trackballs, joystick mouse) by 27 health and safety professionals.
- Evaluation criteria included comfort, control, ease of use, movement, software interaction, and accessories.
- Data synthesis with existing literature to create purchasing and assessment checklists.
Main Results:
- Mice were rated higher than trackballs and joystick mice.
- The standard 2-button mouse (D4) was the most preferred design.
- Specific 3-button mouse designs (D1, D8) also received favorable ratings.
- Key design factors identified: hand/finger comfort, adequate control, intuitiveness, ease of movement, software compatibility, and accessories.
Conclusions:
- Standard mice, particularly the 2-button model, offer superior usability among evaluated NKIDs.
- The identified design factors provide a framework for selecting and assessing NKIDs.
- Developed checklists can aid organizations in making informed NKID purchasing decisions.
