Reliability of Postural Observations in Ergonomic Assessments

This is important research for anyone who performs observational postural assessments. Researchers Bao, Howard, Spielholz, Silverstein, and Polissar conducted a study designed to investigate interrater reliability -- the ability of different observers/assessors to reach the same conclusions when visually estimating posture. Their results indicate that the nature of the assessment tool, large angle categories vs. small angle categories in particular, and the experience and training of the assessor can have significant impacts on reliability.

The Effect of Key Spacing on Typing Speed, Error, Usability and Biomechanics

A team of researchers studied various center-to-center key spacing on computer keyboards to investigate whether current keyboard design standards are conducive to typing performance (speed, error rates), usability, and forearm biomechanics. Current keyboard design standards, oddly, are not based on human performance data, and this study is one of the few that takes a human-centered ergonomics approach to the ubiquitous computer keyboard. Their findings will impact future keyboard design standards, and bring credibility to the phrase "I fat-fingered it," a common explanation for keyboard related errors. Could this study also begin to lay a foundation for different sized keyboards for different sized people?
