In visual perception, change blindness is the phenomenon that occurs when a person viewing a visual scene apparently fails to detect large changes in the scene. For change blindness to occur, the change in the scene typically has to coincide with some visual disruption such as a saccade (eye movement) or a brief obscuration of the observed scene or image. When looking at still images, a viewer can experience change blindness if part of the image changes.
Despite the fact that many in America aren’t paying attention to Iran, the protests there continue. This video shows Iranian police running over people with their vehicles as a means to stop the protesting.
Just what information do ebook retailers know about you? The EFF has a very handy guide to help you out, so that you can make an informed decision on the matter.
For example, Google’s new Google Book Search Project has the ability to track reading habits at an unprecedented level of granularity. In particular, according to the proposed Google Books Privacy Policy, web servers will automatically “log” each book and page you searched for and read, how long you viewed it for, and what book or page you continued onto next:
Physical e-reader devices pose similar threats to reader privacy. For example, the Kindle does not sell, but rather licenses, the books, magazines, and other materials offered for wireless download through its Kindle Store, which can only be used on a particular device. This implicitly requires Amazon to know what reading material a user has licensed at any given time.
Thankfully, there are some e-reader options that do not connect wirelessly, nor include any privacy or “terms of use” provisions that allow monitoring of what you put on the device or how you use it. Sony’s Reader, for example, may collect information about what books you buy from its own eBook Store, yet the Reader also works with books purchased from other sources as well. Even safer still, popular e-reader software programs, such as open-source FBReader, allow users to download content from a number of sources onto a multitude of devices, including one’s computer or mobile, without handing over all information about their reading habits to one source, or anyone for that matter.
