Typical scenarios and influencing factors on speech-handwriting

摘要

Combination of speech recognition and handwriting recognition as a text entry way has been widely used on mobile phone products. However, users seldom use speech recognition to input text. It probably because we didn't know what kind of situation was really suitable for using speech recognition to input text in daily life. The present study tried to answer what were typical scenarios and influencing factors for the combination of speech and handwriting in users' daily life. Three focus groups were conducted. Results suggested that environmental noise and social factors had an important influence on the usage of the speech recognition, while the attention demands and hands occupation limited the usage of the handwriting. Further, the speech-handwriting combination had special advantages in some scenarios, in terms of the entry speed, accuracy, and attention demands. And the combination way was less impacted by the environmental noises and social factors. These findings provided information for further filed studies and system design.
