Some time ago i read about Dasher, an innovatove way of inputting text. I read about it again and wanted to record this on my blog. I found this YouTube-video of someone combining Dasher with Roborealm to input text. Although it doesn't look easy to me, this guy says it is, so it might just be a matter of getting used to... I guess there are some situations and devices in which Dasher might be the perfect way to input text. But you wonder why it hasn't been used commercially yet (i did not research this, i just haven't seen it or heard of it ;-)).
