Queens University Belfast, have developed a new assistive technology that has a tactile as well as sound feedback to the user. Apparently it makes the mouse vibrate and gives a camera type "click" sound every time the pointer passes over an image.

Now other than the obvious comments that I'm sure will instantly leap into the minds of the smut brigade (More images, more images) it raises some interesting issues such as:

Decorative images have no alt text so the useless info doesn't get read out by screen readers but if the mouse tells people there's an image there then surely they're going to want to know what it is.

There's no real detail on the technology available yet and it doesn't say whether it only vibrates on embedded images or on css rendered background images as well.

I discussed this with Mike Cherim and he is of the same opinion as I am, a page with a load of images is going to be too darn noisy. Speech, clicks and vibrates all over the place. Still I shall watch with interest, at the very least users will get a great hand massage. :)

Sounds interesting, and quite useful in theory, but I can't help wondering if it isn't going to be information overload, and like you said, a page with loads of images is going to be far too damned noisy and vibrating....

/tries but fails to keep smutty images from mind :) :)

This morning I was investigating various magnification software for work, and amongst them I found one magnifier/reader that had a very annoying system of musical beeps built in to let you know where the mouse was on the screen. It's makers claimed it wasn't noticeable after a while and you quickly got used to figuring out where you were, but even just the short demo of it drove me crazy - I can't remember which it was now, and FF had a bit of a hissy fit this morning and crashed on me, then wouldn't recover the session, so all the tabs I'd got open disappeared. *sigh*

So, back to the vibrating images, and some rhetorical questions...it clicks and vibrates when it finds an image - does it also read the alt text? Click, vibrate, talk - all in the middle of the text the image is in the middle of....Does it also announce it's an image...but that would be redundant with the vibrating bit. Of course there's the embedded/background images thing, and then what's it going to make of the various image replacement techniques out there? Age old problem of diplay: none, and if the image is on the page will it read the alt text and the actual text which is 0.2456 miles off the edge of the screen if you're using one of those image replacement techniques. Of course there's the empty span trick one that nicely keeps both text and image on screen and only displays the text if the image doesn't load, but of course for the standards police you don't get the nice little green tick with that one....

Whole new can of worms and another sort of technology to take into account when designing....Hmmmm - it'll be interesting to see what users make of it.

I wonder also about those of us who have images amongst text with meaningful alt text that actually forms part of a the sentence for visually impaired people but sighted users don't get that alt text.

Is it I wonder going to vibrate and click over an image when to a blind user they're not going to know that an image was ever there because the alt text was so well written into surrounding paragraph text? And if so, they'll be wondering where the alt text is?

Jaws finds alt text and prefaces it with the word "graphic" so your sentence might not make quite so much sense after all.

Gosh . . . I'll have to try and figure out a way to start all these meaningful sentences with the word "Graphic" from now.

How about "ly speaking . . . " That way it might sound like "Graphically speaking . . ."

Seriously though, the next time I buy another computer, I think I'll dedicate one to JAWS. It was playing havoc with other programs when I downloaded the free version once before so I had no option but to remove it.

No it would sound like

graphic lie speaking

I was given a full version of Jaws last year and on install it did something horrendous to my sound set-up and and display settings but after I'd gone in and reset them all it was fine and seems quite happy.

I think that is one step too far. A site can be too accessible, in fact I would consider that to be aggressive accessibility which is defeating the point of the exercise. Information should be available not shoved in your face.

Wait, I'm missing something.

I would assume the point of such a device would be to assist the blind or vision impaired people out there... but how would such a person see the mouse, to point it to the image to begin with? It makes no sense to me to say "your mouse is over an image" in such a case.

Someone please correct me if I am wrong, and I very well may be because I know precious little about the subject.
