I’m working for a foundation that raises awareness for accessibility in the internet. For a presentation, we want to offer a small workshop that simulates different disabilities/impairments to people. This is done via a website created especially for this presentation.
One of the demonstrated impairments is having a tremor, which means experiencing shaky, difficult-to-control hand movements. With this impairment, it’s very difficult to move the mouse cursor exactly and to press the mouse button while the mouse is over a link. Both some old people and people with disease, e.g. Parkinson’s, can suffer from tremor.
Now I’d like to somehow move the mouse cursor in an unpredictable way, so that it’s very hard for people to click on a small button. Because JavaScript doesn’t allow moving the mouse cursor directly, I’m looking for other ways to achieve this. I came up with the following ideas:
- Using a mouse driver / utility that simulates the mouse shaking.
- Hide the mouse cursor via CSS, place a GIF animation of a shaking mouse cursor at the place of the original cursor (with JavaScript), and then make the target link clickable only every few seconds for a second or so. This would at least give the feeling as if one always clicks at the wrong moment.
While the first idea would be pretty cool, I couldn’t find a tool like this, whether for Mac nor for Windows. And I don’t have any skills in programming such a thing myself.
The second idea seems a bit clumsy, but it would achieve the desired effect, I think.
Does anybody have another idea?
