Toward a Usability Evaluation of BCIs

Year: 2011

Type: article

Abstract: If BCIs could be considered and evaluated as assistive technology facilitating life activities,\nthey could avoid dissatisfaction and prevent abandonment. We tested two keyboard controlled Java BCI\nprototypes, based on the Thought Translation Device and the P300 Speller, on 61 participants with\ndifferent computer skills performing a Copy Spelling Task. We then administered usability and\ncognitive workload questionnaires. The results have shown significant differences in the number of\nperformed errors, in satisfaction, and in the cognitive workload invested in the task. We found that the\nThought Translation Device was more error-resistant, less stressful, and more satisfactory for the users.
