A $20 8-Bit Wikipedia Reader For Your TV 167

Posted by timothy from the thought-experiments-welcome dept.
An anonymous reader writes with this excerpt from Wired about another entry in the ongoing quest for low-tech-high-tech educational tools to take advantage of distributed knowledge: "The Humane Reader, a device designed by computer consultant Braddock Gaskill, takes two 8-bit microcontrollers and packages them in a 'classic style console' that connects to a TV. The device includes an optional keyboard, a micro-SD Card reader and a composite video output. It uses a standard micro-USB cellphone charger for power. In all, it can hold the equivalent of 5,000 books, including an offline version of Wikipedia, and requires no internet connection. The Reader will cost $20 when 10,000 or more of it are manufactured. Without that kind of volume, each Reader will cost about $35."

    I can't imagine that the audience this is aimed at is likely to own an HDTV, so presumably they'll be trying to read masses of blurry text on an older SDTV. Sounds like fun.

      Reading from the screen is not hard. Even on old TV sets. Teletext exists since ages and nobody complains about it being unreadable. In fact in today technological society there are already more people reading more from screens of some kind, than from paper. With such cheap device as the one in the article, the ratio of people reading from screen versus the people reading from paper will increase even more in favour of the ones readering from screen.

And if people don't complain now, it's probably because very few people use it.

        Reading from the screen is not hard. Even on old TV sets.

        Yes. Yes it is. Interlacing is BAD. VGA-resolution is bad. No magic will fix that.

        Teletext exists since ages and nobody complains about it being unreadable.

        Teletext takes up, what, 1/5th of the screen for TWO LINES of text? Yeah, at those sizes, anybody can read them. Trying to read a lengthy document like that proves VERY cumbersome. Non-stop scrolling to the next few lines, and an exhausting experience as your eyes have to travel vastly further than they should, or would on a decent monitor, or book page.

        Yeah, text as 24x80 is readable, but even them, you don't want to be subjected to it, if you have a choice.

        • Teletext usually gave about 500 characters/page plus some graphics. Given its popularity for things like news and sports, i.e. moderately-long articles, in the countries in which it is available, clearly it worked "well enough". As for "have a choice", it goes without saying that a product like this is not aimed at people who have the option of reading Wikipedia on a computer.

      On the other hand, a public library might not be updated as regularly as Wikipedia. Or if your library is like the ones in my neighborhood, the computers often have a wait time. This is something I think would be a great tool to be used in conjunction with a public library. At the start of every semester or school year, some kid's parent could go to the library and download the latest version of Wikipedia. Then the kid can access information at home. I know it's hard to believe, but not every home in America can afford a computer and a $30 a month DSL bill.
