LiquidKeyboard may have substantial ergonomic benefits

As an iPad user for well over 6 months, the iPad is a terrific device for reading but it is not the best for writing. This may be due to having typed since the age of 14 on everything from a solid old Remington typewriter to an IBM golf ball electric typewriter and various keyboards over the decades. Typing on glass is possible but the limited keyboard size on the iPad is a struggle. But that struggle may be replaced by an even greater challenge.

The iPad, and many other devices, are bound by a QWERTY keyboard. Others have argued that the QWERTY layout is outdated but it is possible to produce a presentable email holding an iPad in one hand and typing with the other. It is likely that , over a short period of time, the shortcomings of that arrangement will create ergonomic problems.

Researchers at the University of Technology Sydney (UTS) have not introduced an alternative to the QWERTY keyboard but rather tweaked it into a new layout. LiquidKeyboard is the system and, in short

“A new keyboard that makes it easier to type on touch screen devices has been invented

LiquidKeyboard enables people to use both hands in typing in the traditional way

As soon as your first four fingers touch the surface – in one fluid motion – an entire keyboard is constructed using the QWERTY format”

As with many innovations, productivity is the main motivation or it may be that productivity is the language needed to gain broad media attention but the potential ergonomic benefits are just as interesting. If ergonomics is “the science of designing the workplace environment to fit the user” then the ergonomic benefits of LiquidKeyboard are self-evident. Just because the use of a virtual keyboard has not identified any hazards yet does not mean that research into alternative, more ergonomic methods is not warranted. The forethought of Christian Sax and other researchers is to be applauded.

Independent research into quad bike ROPS safety

In early 2009, Australian engineer, Shane Richardson, completed his thesis into the “Performance Criteria For Effective Structural Rollover Protective Systems For Light Passenger Vehicles”. Part of his thesis included an evaluation of the New Zealand Department of Labour’s ROPS guidelines for ATVs or quad bikes.

Richardson points out that the guidelines have strong similarities to the Australian Standard for protective Structures on Earth-moving Machinery (AS2294) although quad bikes may tipover or undergo a multi-directional tumble, the latter action is not one considered by AS 2294. Richardson believed that the earth-moving machinery “origin” of many of the basic concepts and calculations in the NZ DoL guidelines made them useful but inadequate.

NZ Coroner presses for changes in quad bike safety

One of New Zealand’s coroners, Ian Smith, has set a safety challenge to the OHS regulatory and quad bike distributors. In the coronial findings (not available online) into the 2008 death of 21-year-old beekeeper, Jody Santos, Coroner Smith has recommended to the Ministers for Transport and Labour:

“The Court endorses the new educational and enforcement programme being proposed by the Department of Labour, but considers that both Ministries undertake an immediate investigation to consider the mandatory installation of:

(i) The compulsory wearing of helmets when operating ATVs in any circumstances; and

(ii) The installation of a roll bar on all A TVs/quad bikes; and

(iii) The installation of lap belts on all ATVs/quad bikes.”

The Department of Labour (DoL) specifically requested that the Coroner remove the mandatory installation recommendation. Continue reading “NZ Coroner presses for changes in quad bike safety”

Safety begins to converge to focus on the individual

If further information about the increasing inter-relationships between psychosocial health and physical health, organisational culture and a worker’s mental health was needed, a new study from Sweden provides convincing evidence.

The research, a study of 81 research projects into the links between psychosocial factors and musculoskeletal disorders, was reported in by Eurofound on 10 September 2010. It found, among other issues that

“… The link between an unfavourable psychosocial environment and the prevalence of MSDs is well established, with a number of studies demonstrating that high stress at work is connected to increased risk of developing a musculoskeletal disorder.

What is the OHS “public interest”?

On 7 May 2010 Judge Lacava of the County Court of Victoria increased the $A25,000 fine applied to A Bending Company to $A75,000.

WorkSafe’s Acting Director for Health and Safety, Stan Krpan, said in a media release:

“The fact that the Director of Public Prosecutions [DPP] found the original penalty inadequate, and the increase in the fine on appeal, demonstrates the courts’ attitude towards health and safety offences.”

The DPP made the appeal to the County Court after a request for review of the original fine was made by WorkSafe Victoria. According to the judge’s decision (not yet available online):

“The appeal by the Director is made pursuant to section 84 of the Magistrates’ Court Act 1989. The section gives the Director the power to appeal to this Court “if satisfied that an appeal should be brought in the public interest“.” [emphasis added]

So how was the public interest served by increasing the fine by $A50,000? Continue reading “What is the OHS “public interest”?”

Ergonomics of quad bikes – new research

While the New Zealand government is investigating agricultural safety issues, researchers from the University of Otago have looked at the ergonomic issues associated with the loss of control (LOC) of quad bikes by drivers.

According to a University of Otago media release, researchers Dr Stephan Milosavljevic and Dr Allan Carman published a paper in the current edition of Ergonomics. The researchers

“….set out to analyse the driving behaviour of people who regularly use quad bikes, recognising a need to find out why people lose control of them so frequently.

Of the 30 male rural workers and farmers studied, 19 of them, or 63 percent, had experienced loss of control on a quad bike. They were in their mid 40s on average, and about eight to nine years younger and less experienced than those who did not lose control. Continue reading “Ergonomics of quad bikes – new research”

Safety professionals must understand RTW in order to avoid unnecessary costs

The rationale for the Australian government’s evangelism of harmonisation is the reduction of “red-tape” on the logic, or assumption, that business costs will also be reduced. Dr Mary Wyatt, according to a report on ABC News Online, says that cost reductions may be possible be reducing over-servicing of injured workers.

Dr Wyatt says:

“We have an increasing focus on the medicine, and we have lots of scans that tell us there are things wrong with our bodies, and then when those scans are done it’s often labelled as a serious problem, and then the worker gets worried and we often go off on a tangent..” Continue reading “Safety professionals must understand RTW in order to avoid unnecessary costs”
