Abstract:A healthy work-to-rest ratio during computer work can be an important part of successful preventive workrelated upper limb disorders (WRULD) intervention. Existing break software applications designed to realise such a work-to-rest ratio often possess product features that limit their functionality. Most applications focus on physical relaxation by implementing (micro) breaks into computer work time. Through the emphasis on break time, these applications give the impression that there is no productivity, possibly strengthened by the applications themselves that often visualise the remainder of the break as a slowly decreasing time bar. Moreover, application features such as blocking input devices may counteract cognitive relaxation of computer workers. As imposed physical breaks can be cognitively stressful, especially when deadlines loom, combining physical and cognitive relaxation is a challenge. Actually, research shows that, instead of micro breaks, macro breaks need more attention. It is worthwhile to think of new products for both forms of relaxation within this time span. An idea for a possible product innovation is tested with a small sample and is presented here: a new software application that shows customisable video content during macro breaks.
