Abstract
Communication barriers in classroom settings continue to limit the participation of students who are deaf or mute, highlighting the need for practical assistive technologies. This study evaluated the performance of GABRIELLA 2.0, an improved sign-language assistive robot developed to support communication in educational settings. An experimental research design was employed to compare GABRIELLA 2.0 with its earlier version, GABRIELLA 1.0, through controlled testing. Performance was assessed across accuracy, latency, execution speed, electrical behavior, and solar charging capability, with 10 trials per parameter. The results showed that GABRIELLA 2.0 demonstrated faster response times, more consistent movement execution, and improved power consumption consistency compared to the previous version. Although accuracy decreased, the results remained consistent across trials, indicating stable gesture execution. Overall, the findings show that GABRIELLA 2.0 prioritizes operational stability and responsiveness over maximizing accuracy, supporting its suitability as a prototype assistive communication system for controlled classroom use.
