Usability Evaluation of A Braille Tactile Audio Device (B.T.A.D.)

Abstract

This research investigates the assessment of the BTAD (Braille Tactile Audio Device) concerning its physical attributes, sound weight, texture, and learnability. Employing a descriptive research design, the study thoroughly examines the usability of the BTAD. Nine purposely selected participants from Cebu, Philippines, individually utilized the BTAD to evaluate it using a researcher-developed questionnaire. The analysis revealed six principal themes: affirmative observations regarding the physical attributes of the BTAD, negative observations regarding its physical characteristics, amplification of sound volume, portability aspect of the BTAD, texture consistency, and ease of manipulation. Findings indicate a mixture of satisfaction and areas for improvement among users, particularly highlighting volume concerns, which are crucial for visually impaired individuals dependent on auditory cues. Consequently, the study recommends enhancing the volume and durability of the device. Future researchers are urged to consider user feedback and prioritize suggested improvements to develop a more refined and functional BTAD.
