Title DICIT: Evaluation of a Distant-talking Speech Interface for Television
Authors Timo Sowa, Fiorenza Arisio and Luca Cristoforetti
Abstract The EC-funded project DICIT developed distant-talking interfaces forinteractive TV. The final DICIT prototype system processes multimodal userinput by speech and remote control. It was designed to understand both naturallanguage and command-and-control-style speech input. We conducted an evaluationcampaign to examine the usability and performance of the prototype. Thetask-oriented evaluation involved naive test persons and consisted of asubjective part with a usability questionnaire and an objective part. We usedthree groups of objective metrics to assess the system: one group related tospeech component performance, one related to interface design and userawareness, and a final group related to task-based effectiveness and usability.These metrics were acquired with a dedicated transcription and annotation tool.The evaluation revealed a quite positive subjective assessments of the systemand reasonable objective results. We report how the objective metrics helped usto determine problems in specific areas and to distinguish design-relatedissues from technical problems. The metrics computed over modality-specificgroups also show that speech input gives a usability advantage over remotecontrol for certain types of tasks.
