A comparison of speech and GUI input for navigation in complex visualizations on mobile devices
Rui Zhang, Stephen C. North, Eleftherios Koutsofios · 2010
Mobile devices are ubiquitously used to access web applications. Multimodal mobile interfaces can offer advantages over less flexible approaches, in both usability and range of features. In this study we consider applying speech input to a web-based network management service. The key issue we are interested in is how to perform suitable multidimensional search through web-based interface on mobile devices. We present results from a pilot user evaluation, focusing on the comparison of a novel speech input method with the existing manual (GUI, Graphical User Interface) input for AT&T's Visualizer management service, on an iPhone. Speech input was experimentally shown to be as effective, more efficient, and preferred over GUI input by most users. We foresee that a multimodal approach may be preferable for many applications on mobile devices.
