Towards a taxonomy of error-handling strategies in recognition-based multi-modal human–computer interfaces

Marie-Luce Bourguet
2006 Signal Processing  
Our lack of understanding of how recognition-based technologies can be best used and combined in the user interface often leads to interface designs with poor usability.  ...  Every study of recognition-based human-computer interfaces shows that recognition errors reduce the effectiveness of natural input modalities such as speech and handwriting [10][11] [12] .  ...  Rule-based grammars are used to limit the range of possible inputs that a recogniser will find acceptable and hence limit its research space and the risk of recognition errors.  ...
