Text Input Methods for Interactive TV Systems

Leuven.
We begin the next session at EuroITV 2009 with Gijs Geleijnse from Philips. He notes that many of the new innovations in the interactive TV area will require new user interfaces - for example for text entry on television screens. Ideally this would happen without adding yet another device to the living room (i.e., not another remote control...).

Gijs's study examined a number of options for this - multi-tap (SMS style), an on-screen keyboard, and a regular computer keyboard. It evaluated the usability as well as the enjoyability of such technologies - and the standard computer keyboard won out on both measures.

Additionally, the study explored whether these results would change with the addition of predictive or smart text entry. Here, the standard keyboard remained the fastest, but the other input methods were now also rated as reasonably useful and enjoyable. An on-screen keyboard turned out to be the best alternative, if smart entry is available.
