World Leading Research Into Computer Use Released at International Conference
Media release, 6 December 2007, Christchurch, New Zealand: Christchurch based software developer Wellnomics Ltd has
achieved a world first with the release of an analysis of the behaviour of nearly 50,000 computer users across 95
organisations in Europe, North America and Australasia.
Wellnomics managing director Dr Kevin Taylor recently returned from presenting the research findings at the world's
foremost conference for research into RSI (also known as musculoskeletal disorders or MSD's) – PREMUS 2007 held in
Boston, USA.
Data presented by Dr Taylor included some surprising revelations about computer use that challenge previously held ideas
about how long we spend on our computers at work.
The Wellnomics data indicates that in past studies based on self reporting, computer users have consistently over
estimated the amount of time they spend on the computer at work each day.
Observational studies have shown that self reports are inaccurate by 40% - 100%, almost exclusively on the higher side
of the equation, according to Dr Taylor.
The Wellnomics data is based on 'odometer' software installed in the computers of workers in the study to record
keystrokes, mouse clicks and time at the computer, and has been demonstrated by observational studies to be highly
accurate.
"Our data indicates that on average workers use their computers just 12.4 hours per week or 2.4 hours per day over a
five day working week," Taylor said.
Only 12% of users had average computing use exceeding 20 hours per week, with less than 1% exceeding 30 hours per week.
"It seems that we all spend less time working at our computers than we imagine," Taylor says, "and in fact, those few
people who recorded more than 30 hours a week on the computer were working well beyond standard business hours to
achieve those levels."
Other data collected in the research included which applications were used the most, and which types of computing users
spent the most time doing.
No surprises to learn that email took up the biggest chunk of time at 28%, with internet browsing following in second
place at 18% and word processing 15%.
Taylor says one of the most important areas of discussion he believes will emerge from the study is around the
guidelines set by governments and corporations for safe amounts of computer usage.
"Currently we have guidelines set at around 5 – 6 hours per day in various countries, based on the self-reporting
studies which have now been found to be inaccurate.
"The reality is that the current level of injuries is coming from far lower levels of computer use than first thought.
"If we are seeing high incidences of computer related RSI with average work computer use of only 2.4 hours per day, then
new guidelines need to be developed urgently."
Another conclusion Taylor wants to highlight is that mouse usage is more important than the number of keystrokes as an
indicator of risk.
"The fact that the rates of mouse usage are high, and the number of keystrokes is relatively low, supports the
scientific consensus that it is not repetitive actions like typing that are the major cause of RSI amongst computer
users, but actually static posture and muscle tension that causes problems, especially that required by using a mouse.
"Of course this study only covers the work environment, and we have no record of home computer usage, which anecdotally
we would expect to be climbing as browsing websites, talking via instant message sites, loading music and viewing
downloaded podcasts, movies and television clips becomes more and more common as an alternative to television watching
at home."
Other information provided by the research indicates some significant differences between countries in terms of computer
use, with UK users putting in the most hours on the computer (16.8 per week) and also the highest number of keystrokes
per hour of computer use. Following behind the UK are the US and Australia with 14.5 and 13.6 hours per week
respectively.
Norway and the Netherlands had lower numbers per week, but this might possibly be attributed to there being more part
time office workers in both countries. The number of keystrokes per hour in the Netherlands was third behind the UK and
Australia.
The New Zealand sample used was not large enough to be included in the comparison of countries.
The Wellnomics odometer data is derived from its WorkPace breaks and exercises software that is used by more than 1.2
million computer users worldwide. The data is expected to be used by a range of organisations, including LogiTech in the
development of new keyboard and mouse designs, and Dutch research institute TNO have already incorporated information
from the data into new algorithms developed for the Wellnomics Risk Management software.
Wellnomics has a strong focus on research in the office ergonomics field, and is the only New Zealand company
represented on the US based research funding organisation, the Office Ergonomics Research Committee (OERC). The company
has a research partnership with the Netherlands based TNO Work and Employment Institute and provides software research
tools to many researchers in the office ergonomics field across Europe, North America and Australasia.

About PREMUS:
PREMUS is an international scientific conference that serves as a forum for work-related musculoskeletal health research
with an emphasis on prevention of work-related musculoskeletal disorders (MSDs). The participants include international
experts in the field, including scientists, practitioners in occupational health and safety, ergonomists, economists,
industrial engineers, and policy makers. The goal of PREMUS is to present and discuss the latest research. All keynote
speakers are by invitation only and are recognised for their leadership and their international expertise. All
presentations go through a peer review process ensuring high quality of research. As a result, PREMUS is the premier
conference for work-MSDs.
Over the past 20 years, PREMUS has been organised every three years. PREMUS 2007 was the first time the conference was
held in the United States.
