Digression I suppose, but probably worth bringing up anyway. On 2011/08/18 19:46 (GMT-0400) Roger Hudson composed: > The question of text resize I think is very interesting.

It refers to http://www.dingoaccess.com/accessibility/mature-age-ict-users-survey-2/, from which I'm quoting the following: "A significant proportion of older web users who find that the size of the text on a page makes it difficult to read are likely to leave the site and look elsewhere for the information." "At this stage, it would be unwise for government and business to rely on the web (and social media in particular) as a medium of communicating to this section of the community." I strongly believe the two quotes above are worth emphasizing. I live in a county where the average age has consistently been highest or 2nd highest in the state the whole time I've lived in the county, in one of the United States with highest average age of its population. I not infrequently participate in informal surveys in waiting lines, parking lots, computer aisles in WalMart or Best Buy, anywhere one runs into local residents more than briefly. Since I occasionally fix computers as an adjunct to other work, I get to ask survey type questions as part of the repair process as well. Some observations: Some just can't learn to use a touchpad, mouse or trackball adequately, or at all. Alternatives to them cannot be found in the local stores in which most non-computer users shop. A disproportionately high proportion of elderly here have little or no local blood kin to rely on for physical assistance. Clearly of this group few learned computers during formal schooling. Solutions are neither to be found in stock in local stores that sell computers or their accessories. Some look at a screen, or a row of them on a store shelf, and complain everything is too small, not just web page text. To many, bigger is naturally equated to bigger objects, just like TV, not more space for same size objects. There's minimal correlation between display sizes and the sizes of objects displayed on them. No doubt that's due to variations in pixel density, but it's nevertheless a shopping complication that leads to difficulty choosing, and buyer's remorse, or just avoiding buying (or adopting a freebee) at all. Visual deterioration doesn't just manifest in a need for bigger when bigger means wider. As vision goes so often goes field of view, making increased screen (& window) width useless. The important measure of size for many is height. For them, the marketing switch to wide aspect screens narrowed the selection of worthwhile choices. No small number find a sizing solution in Display Properties -> Settings -> Screen Resolution, finding legibility improvement from largeness to far outweigh the resulting poorer quality of images and glyphs rendered at lower pixel density, or distortion from using 1024x768 or 800x600 on a wide aspect screen. When I show someone how to enlarge desktop or web page text size, it's not unusual to get an "I had no idea" type of response, to which I reply something like "you don't expect to be able to personalize your personal computer beyond changing the desktop's background picture?!?" I think a larger sample size "seniors" survey is warranted that's directed at accessibility reasons why the older generations don't use the internet. I've yet to find any such reported. -- "The wise are known for their understanding, and pleasant words are persuasive." Proverbs 16:21 (New Living Translation) Team OS/2 ** Reg.
