Instant messaging comprehension with non-keyboard composition
Jeffrey D. Campbell, Christine Naclerio · 2006
A comparison of the accuracy of comprehension of Instant Messaging (IM) messages composed using a keyboard, handwriting recognition and speech recognition was performed. The participants in the study were shown text messages either containing no errors or having errors caused by typing, handwriting or speech recognition. They demonstrated their understanding of the messages by correcting the errors as they retyped the messages. The time to correct typographical errors was not significantly different from the time to type messages without errors. Speech and handwriting recognition errors in the text took significantly longer to correct than typographical errors, and the results were significantly less accurate. Interestingly, participants expressed slightly higher confidence in their understanding of messages containing speech recognition errors than handwriting, but the accuracy results from those two categories were not significantly different.
