Effects of a Multitouch Keyboard on Wrist Posture and Typing Performance

A dataset from a laboratory experiment comparing a prototype MultiTouch keyless keyboard (MTK) against a conventional keyboard (CK). The study involved 12 subjects (6 males, 6 females) performing typing tasks over two non-consecutive days, with quantitative measures of speed, accuracy, and wrist posture collected. The research was conducted by Jennifer Thom-Santelli of Cornell University.

Use Cases

• Compare typing speed and accuracy between keyboard designs based on the described experimental results.
• Analyze wrist extension and posture data to assess ergonomic risk based on the described goniometer measurements.
• Evaluate short-term learning effects on typing performance for novel keyboard interfaces based on the described linear trend analysis.
• Study user preference and comfort ratings for different keyboard technologies based on the described self-report questionnaires.

Strengths

• Includes data from a controlled laboratory experiment with 12 subjects.
• Measures multiple quantitative variables: typing speed, accuracy, and wrist posture via electrogoniometer.
• Uses a repeated-measures within-subjects factorial design for direct comparison.
• Reports specific statistical results (e.g., F-values, p-values) for key hypotheses.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
