Badly designed Web sites may have negative effects on a user's immune, cardiovascular and nervous systems, a study says.
The study of 2,500 users was commissioned by Rackspace Managed Hosting and published by the United Kingdom's Social Issues Research Centre. It found that five technology flaws in Web sites may have deleterious effects.
Those defects, which can lead to "Mouse Rage Syndrome" are: slow-to-load pages, confusing or difficult-to-navigate layouts, excessive pop-ups, unnecessary advertising, and site unavailability.
The tests, which measured users' brain waves, heart-rate fluctuations, muscle tension and skin conductivity, concluded that few users remain calm when faced with these bad Web-site features.
Among the first signs of Mouse Rage Syndrome were quickened heart rates, increased sweating and teeth-clenching. Users also responded to bad Web sites by furiously clicking on the mouse, scrolling and cursoring across the screen, and bashing the mouse.
