Objective: We performed a usability test for the speech therapy solutions Smart SpeechTM and Smart NasometerTM to apply usability testing results for the development of an optimal speech therapy solution.
Materials and Methods: A total of 19 health professionals (12 doctors and 7 speech therapists) practicing speech therapy were recruited. They performed a usability evaluation by simulating speech therapy tasks for the speech-impaired after being familiarized with Smart Speech and Smart Nasometer for 30 minutes. The participants performed the tasks using oral training contents, breathing training contents, and vocal training contents of Smart Speech. Then, they conducted tasks of wearing Smart Nasometer and checking nasalance data measured by Smart Nasometer. Lastly, they completed a satisfaction survey of Smart Speech and Smart Nasometer.
Results: The usability evaluation showed that more than 60% of the participants were satisfied with Smart Speech and more than 50% with Smart Nasometer. The participantssuggested improvements of Smart Speech in the game description, content color, guide video, audio, data analysis and management, and difficulty-level control function.
Conclusion: The results of this study showed the importance of usability evaluation with users when developing healthcare devices.
