Abstract: | This article considers the success rates in a multimodal command language for home robot users. In the command language, the
user specifies action types and action parameter values to direct robots in multiple modes such as speech, touch, and gesture.
The success rates of commands in the language can be estimated by user evaluations in several ways. This article presents
some user evaluation methods, as well as results from recent studies on command success rates. The results show that the language
enables users without much training to command home robots at success rates as high as 88%–100%. It is also shown that multimodal
commands combining speech and button-press actions included fewer words and were significantly more successful than single-modal
spoken commands. |
