Posted By Penfold Has anyone ever come across the use of screen magnifiers (DSE)? We have some software with a font size that is very small. If we increase the screen resolution, you loose a lot of the page. Our DSE users all have eye tests and complete DSE training/self assessments. I am quite happy they we 'comply', but it is this one piece of software that is causing the problem. We have contacted the software company and to change it would be expensive. I have got it down to 4 individuals who are having problems. They all have recent eye tests and glasses. The simplest solution would be a screen magnifier. Has anyone come across these, where can I get them, and what (if any) are the problems with them. Thanks if anyone can help

Posted By Ian Blenkharn I have used screen covers that make it impossible to view the screen from even a few degrees off centre - to protect confidentiality - and a screen cover similar to a reverse fresnel lens that was supposed to magnify. The latter was used to view a screen through a glass panel in a high security bio lab. It was successful to a point but the clarity was reduced so largely counterproductive Why not a bigger better screen - they are cheap enough If not, software screen magnifiers are common, and usually free. The degree and the area of magification can be adjusted by the user, as can teh area of the screen where the magnified region is displayed

Posted By Bob Youel In my experience if you need magnifiers for average users there is something wrong with your DSE kit, the operator/s, the operating environment - I suggest you explore these routes to find a cure as I thought all such kit for the average user was very old hat or have I missed something?

Posted By CW Cant you just magnify the screen without changing resolution? Not knowing what the software is, this may be duff info. You can alter via the control panel or if it is a microsoft application (which I'm doubting) then click on view - zoom and change size, it may bring up side and bottom scroll bars though. On some PC's you can also alter by holding down Ctrl and press the + or - at the same time.

Posted By steve e ashton Penfold: You are probably already aware that the DSE Regs only put responsibility on the employer... Not (unfortunately) on the software developers. I suggest that you are not 'OK' with the Regs, since there is a responsibility to ensure that equipment meets the standards set out in the Schedule. You write "We have some software with a font size that is very small" yet the schedule requires that the 'the characters shall be well defined and .... OF ADEQUATE SIZE....etc". So - if the software is 'new' (i.e. written or developed since 1992 - and that applies to the vast majority of applications now in use in most workplaces!) then I would suggest that any cost involved in amending the software to provide on-screen font of a reasonable and readable size - is a cost that should be borne by the software supplier / developer. They have arguably supplied something that is not 'of merchantable quality' - it doesn't allow you to comply with your legal obligations. Unfortunately, what is a 'reasonable size' is not defined anywhere - and may depend on the size of screen that is used. You will probably find the developers all work with 26 inch screens, when users are forced to use the 12 or 14inch models stuck on their laptops.... I have had this argument with too many suppliers - and with internal software developers at various employers. Too many in the IT industry are unaware of end-user employer obligations. It would be great if there was an explicit duty on suppliers and developers. But the only thing that springs to mind is the "Sale of Goods Act" - and that isn't explicit as to IT software.. Try to train / educate your IT people and your procurement team as to the difficulties they are stacking up for the future through their ignorant specification of something that is not fit for purpose.... And perhaps try re-opening the dialogue with your software supplier / developer? In my (limited) experience - screen magnifiers are not worth the bother and expense - for the reasons outlined in earlier responses. Good luck Steve

Posted By Penfold Hi guys. Sorry for the late response. I have been away for a couple of days. Thanks for all the advice. I am due to visit this centre within the next couple of weeks and wanted to be 'armed' before I go in. Some of your tips I will try when I visit. 'bigger screens' the MD will have a fit!! They have just had new screens to try and solve the problem. We are talking around 200 users of this software (although only 4 are kicking up a fuss). Steve. Thanks for all the advice. Could be useful if I come to a brick wall.

Posted By LJ Most PC's have a built in magnifier- Go To control panel- click on Accessibility Options- top left hand of screen you will see Magnifier- once you click on this it also gives a 'pop up' that gives you further information. Regards LJ

Posted By Ron Hunter Steve and others: is this software not an article supplied for work use, and therfore subject to Section 6 of the HASAWA, perhaps referencing (e.g.) ISO 14915 and IEC 61997 as applicable standards?

Posted By steve e ashton Ron: Does the ISO guide identify a 'minimum font size' please as a 'standard' for what may be considered 'adequate'? (I can't access it at the moment) (Apologies to those who are not interested in technical stuff - look away now)... An article in the ILO encyclopedia suggests that the 'optimum' character size equates to an on-screen 3-3.5 mm. (Roughly 20-22 minutes of arc from the eye). They suggest that characters smaller than about 16mins of arc should not be displayed as readable text. But this figure appears to assume 'high definition' quality screens (which many are still not) and reasonable ambient lighting conditions, and a clear font (only a few dozen fonts are recognised as being 'readable' against several thousand now available for use)... (And several 'technical' issues like flicker jitter contrast colour and sharpness.) Legibility and readability are about far more than just font size. On my laptop screen, that makes the IOSH discussion forum font 'too small', but it's OK on my (larger) slave monitor. And I have worked with 'low definition' screens where even 5mm characters were indistinguishable from each other. (I'm old enough to remember.... but we don't need to go there do we?) Long story short - the ILO encyclopedia article (for those still here!) is available at http://www.ilo.org/safew...lish?d&nd=170000102&nh=0 It makes for good reading if you suffer badly from insomnia. BUT eventually, it all comes down to subjective judgement of what is acceptable to the individual... Which is where I came in... The Regs require 'adequate size', and there is (as yet, so far as I know) no accepted (UK Courtroom accepted) definition of what size in law is deemed 'adequate' in particular circumstances and for particular individuals. And remember we are all individuals, and what is problem for four employees as described by the OP is (likely to be) a problem for the business. Steve

Posted By Ron Hunter Steve, I was 'fishing'a bit there regarding applicable standards. BS EN ISO 29241 may also be applicable (Parts 10 -17 I think). I was more interested on thoughts re the application of HASAWA Regulation 6 'supply'. Many of us will be involved in specifying aspects of software applications, it would be useful if anyone out there is aware of a more accessible "industry" guide or Code of Practice that could be referenced in Tenders and Contract terms so that we can avoid the kind of problems Penfold is experiencing now!
