iPads and other LCD tablets are widely used in educational settings. They are ‘do it all’ devices which can perform many functions. They can be cameras, music players, web browsers, as well as displaying text word processing or notetaking software, or in book apps such as Kindle, iBooks, Wattpad, BorrowBox, and so on.
Tablets are great for research, gameplay, recording and creating content, as well as being platforms for reading. Their responsive touch-screen interface is intuitive enough for even toddlers to use them for animated video and simple games. On the other hand, eReaders such as the Kindle, Sony eReader, and Kobo, are single function devices – they are meant simply to read on!
Adolescents participating in the Teen Reading survey were much more likely to have regular access to a tablet rather than an eReader. Many of the comments made by teens highlighted their iPad/Tablet’s attractiveness for playing games on, but also indicated that they used their tablet in both recreational and school settings.
But when asked about barriers to reading more on devices, those with access to a dedicated eReader were half as likely to report eyestrain than tablet users.
This is probably because eReaders use electronic ink, specifically designed to mimic the appearance of print on paper, and studies have shown that they are perceived by adult users to be as readable as print. They reflect ambient light rather than emitting light. On the other hand, iPads use backlighting as a screen technology. They look very much like computer and video screens, and emit light waves which, as with other kinds of screens, has been associated with visual fatigue.
Perhaps the added dynamism and different eye-tracking movements required by linear media and gameplay allows users to ignore that tiredness more readily than when reading!
Thanks a lot for excellent article, your advice is very useful to me.
Glad you found it useful
Very interesting! Are you also researching the effects and value of the static image on paper and screen?
