Microsoft “Natal” technology – the dawn of a new age in ergonomics?

In an interesting development, Microsoft has publicly shown at 2009 E3 a next generation games system controller labelled ‘Natal’ that is free of buttons and joysticks; the controller is essentially you. It relies on a sophisticated camera detection system to monitor the user’s motion and translate this motion into games controls. It also has a voice recognition engine. In an article on the BBC news site entitled ‘Microsoft previews new controller‘ a video shows a demonstration.

The reason that developments like this are exciting is that the games business, being a cutting edge, technologically advanced industry, usually pushes the boundaries of software and hardware development for the sake of market share.

Technology like this for, say, computer controls would ordinarily evolve a lot slower if there were a lesser need for it aside  from gaming. However, once developed, you can see how it could easily transform into some kind of gesture control for computer operating systems and applications. Who knows, you may even get a workout whilst doing a spreadsheet in the future!  Will a workout mat eventually replace the old desk?  Maybe we can eliminate the need for going to a gym!  Do employers only hire fit people in the future?

We are certainly at a crossroads with computers, where the basic mouse has been around too long and has created too many overuse injuries. It is more than time that we took computer input to a new level of evolution, and this may be the glimpse of what’s to come.

Whether this technology can save us from RSI related injuries is unknown, but it may help wean us off using a mouse. It may also lead to opportunities in computer use for people with all kinds of different disabilities, and not just RSI.

Is this the dawn of a new age in computer ergonomics, or is it just a gimmick ?

Breaking the RSI Pain Cycle

Breaking the RSI Pain CycleThe RSI pain cycle is the cycle of pain that a RSI sufferer can be locked into with their condition. The first diagram on the right (click image to enlarge) should allow a sufferer to understand the underlying mechanisms of the RSI pain cycle and realise that there may not be one single ‘magic bullet’ to address the RSI pain.

The RSI pain cycle once ‘locked’ into is a hard one to break free from. The common mistake is to address only one or two factors. If the sufferer is at an early stage of RSI, and is fortunate then one change eg ergonomic setup may be enough to break free, but any medium/long term sufferer who is trapped in this cycle should consider addressing most/all of the underlying trigger causes to allow the transition to an RSI free life. The second diagram (click image to enlarge) shows the key areas to address to break the cycle.Breaking The RSI Pain Cycle

Trigger Finger and RSI?

I’ve just been dealing with a bad case of trigger finger – a condition where a finger becomes locked in a gripped position.

It’s happening (quite badly) on the middle finger of my right hand – so much so that I have to use my other hand to prise the stuck finger open again! I also have minor trigger symptoms on some of my other fingers. It’s not just an inconvenient condition, it can be quite painful too! Usually trigger finger cases can clear up with some rest, ice and anti-inflammatory medication but this one has been with me for quite some time.

The trigger condition has been diagnosed as such by doctors, and has been treated twice with steroidal injections (to no avail). Surgery looks like the next option for me to relieve this condition, and is only a day patient procedure done under

Are you at risk of developing RSI?

questionmedBelow, I provide a list of criteria that I would associate with a worker who will have an elevated risk of contracting an RSI condition. If you associate with a few of these activities, then you too may be at high risk of developing a RSI condition –

  • Computer operator professional or otherwise
  • Deep in concentration about your work, intolerant of interruptions
  • You slouch at your desk, peering at the computer screen, unaware of your posture
  • Working on a key project with tight deadline
  • Stressing about achieving that deadline
  • Working in a competitive environment in uncertain times
  • Spending your work time at a computer for 5-10 hours a day
  • Taking minimal breaks, and most of these are spent checking email /surfing the web
  • Lunch is frequently a sandwich eaten at your desk whilst working
  • You are a heavy coffee drinker
  • You spend a cumulative 30 min/day sending text messages on your mobile phone
  • You go home after a 10 hour day and relax by ripping some CDs to mp3, updating your iPod, catching up on personal email and unwinding by playing a ‘shoot ’em up’ on your computer/games system for 2-3 hours
  • You spends 6-8 hours sleeping before starting the cycle again

Lets break down each point and try to inject some solutions –

Video Games and RSI

Games ControllerAn interesting article appeared in the Times Online titled  “Doctors identify ‘PlayStation palm’ as a legitimate medical complaint” which takes a broad look at how more and more types of repetitive strain injuries originating from use of video gaming machines are being discovered. It should be noted that a ‘video gaming machine’ can encompass the set-top box variety, a full-sized PC or indeed a miniature hand held device, the only difference being the types of repetitive motion that the users engage in order to interact.

It should also be noted that video gaming is a highly addictive pastime (I speak from the experience of my youth). Video games are designed to be addictive; let’s face it, if they were not, players would rapidly lose interest and move onto something else, and the manufacturers would not sell many games.

There are usually very high levels of

Addicted to Technology

needle1.jpgWe are a species that spends most of our lives battling addictions of one sort or another – ranging from what we consume to television to news, the list is endless. Our addiction to technology is no different. The cool technological gadgets that adorn our lives are just so addictive!

There are so many ways today to fritter away huge amounts of our time in our new virtual worlds. Have you ever played a video game and noticed how 3 hours of your life just disappeared?

Technology has brought us immense benefits as a society, but it has also made us slaves to a great extent, and we spend ever increasing amounts of time interacting with devices whether they be computers, mobile phones, PDAs, games consoles, MP3 players, GPS or TV remotes.

A substantial portion of employment now involves working on computers, whether it be the inputting/analysing of data, or the creation of the latest software that controls our lives. The trouble is that, the more high technology we introduce to our lives, the more time we spend interacting with it, often to the disadvantage of our health. It’s not too hard to imagine that, if current trends continue, there will be a technological gadget to interact with from the moment we wake up until the moment we fall asleep (or more scarily from the moment we are born until the moment we die!).

The Web has expanded the information available at our fingertips by a staggering amount. It has also changed
