Hi All,
Can anyone recommend a cost effective screen magnifier for DSE work .We have been introduced to a new LA client system which is approx third full screen. As it is Oracle based our IT whizz guys cannot seem to expand the image using commercial software or pixel size(it distorts) so in short term desperation ( hopefully ) we may have to use old world magnification. Can anyone recommend such !!!!
Regards, Paul

I am not that IT able so maybe this won't work or you have tried it already, I realise you said it wasn't a Windows style package but...
Start/Programs/Accessories/Accessibility/Magnifier...from your start up menu in Windows might work.
Only a suggestion. Sorry if it has already been tried.
Jeff

I remember dealing with someone who had iritis some years ago. I seem to recall we got hold of a large magnifying glass (say, size of one of those [alleged] anti-glare screens).
Seemed to do the trick. They used it for manuuscript reading too.

I suggest you contact the software manufacturer. I would not see using a magnifying glass all day long as a long term solution. Surely it must be fixed at the software end.

Quite right, Maria.
Should've mentioned the guy was awaiting an operation so it was a short term solution.

With reference to the Schedule attached to the DSE Regs in UK. you are letting the software guys off the hook here.In my humble opinion, a magnifying screen isn't satisfying the requirements of the Schedule.
"Schedule: Minimum requirements for workstations
(Which sets out the minimum requirements for workstations which are contained in
the Annex to Council Directive 90/270/EEC(a) on the minimum safety and health
requirements for work with display screen equipment.)......
2 b) Display screen
The characters on the screen shall be well-defined and clearly formed, of adequate size and with adequate spacing between the characters and lines."

I agree that a magnifying glass is not the way to go. The software - including the image on the screen - should be suitable for the user. Have another word with the IT people!

Hi Paul
This may be teaching grandmother to suck eggs.
But here goes, Your network server allows your terminal to access the windows software loaded on it, so you have very little information on the screen when you start up. Only a guess,cos you did not specify in the thread. If the area displayed is in the middle of the screen it sounds like the software on the server is at fault. If the display is in any of the corners then parameters set in the client information by software engineers (IT) guys may be incorrect. Best bet contact the people who installed the system,don't waste your time its what you paid them for in the first instance.
Best of luck Alan N

Thanks All,
As stated this was to be a short-term solution. I had already spoken to Ability net who could not help with an Oracle based system. Thanks Alastair a very interesting site. I particularly liked the TV screen enlarger,'site for sore eyes'.Also be ensured we are battling with the software / IT people to get this resolved. How this system came through a pilot stage & sold to LAs is a wonder(polite !!!)For those interested the system is called 'SWIFT'
Thanks again.
Paul

I have encountered similar issues with software not allowing for character size adjustment.
The HSE guidelines make reference to BS/EN 29241.
The BS/EN has a graph relating character size to viewing distance. My interpretation of this is that if viewing at 400mm distance then chars. should be at least 1.9mm high, at 500mm, must be min. 2.3mm and at 600mm, must be min 2.8mm.
Have others referred to this BS/EN, and would you agree with my interpretation?
Would anyone have any opinions on viewing distance? The BS refers to viewing at 400mm from eyes to screen, but is it realistic to expect people to view so close?
If the users do not find it comfortable to view any closer than 500mm., does this mean characters have to be 2.3mm high as a minimum.
Does anyone know whether there could be real damage to eyesight if characters are say 10% less than the size per BS/EN?
Incidentally - are the IOSH software designers also in breach of regulations?? As I type this, the character size is only 2.0mm, and I cannot adjust it!!!
