A usability evaluation model for hearing-impaired mobile applications

Hearing-impaired are one of the disabled community that rely on mobile application for daily use which in need of usable application. However, existing usability evaluation models are difficult to be applied for hearing-impaired mobile application evaluation due to the generalized measurements which...

Hearing-impaired are one of the disabled community that rely on mobile application for daily use which in need of usable application. However, existing usability evaluation models are difficult to be applied for hearing-impaired mobile application evaluation due to the generalized measurements which includes limited description on the hearing-impaired requirements for mobile application. Moreover, existing usability evaluation models do not provide description to be followed for usability evaluation to be conducted. Thus, objective of this study to proposed a usability evaluation model for the hearing-impaired mobile application interfaces. User requirement and systematic literature review are used in generating a set of usability dimension, criteria and metrics. The model was verified through expert review in term of consistency, ease of use, understandable, verifiable and overall impression. Moreover, domain experts validated the model through a focus group approach that measures on model presentation, interface and task support satisfaction while usability testing was conducted with hearing-impaired to validate on data collection reliability of the model. Objective and subjective data were collected from total of 20 hearing-impaired who have participated. Descriptive statistics analysis were performed through statistical tool and reported on the validity of the data in yielding result in real environment. Findings from user validation shows reliability of the data obtained. Expert agreement and user data validity test shows the reliability of the proposed model in real environment for usability evaluation of the hearing-impaired mobile application. The model is expected to be applicable for all mobile application developed for the hearing-impaired in ensuring usefulness of those applications. The model is also expected to provide guideline in designing usability model for specific applications and the measurements incorporated are identifying particularly on hearing-impaired needs. Conclusively, this study presented a new usability model for the hearing-impaired mobile application and as an additional knowledge to usability practitioners and developers on how to apply the model in development of hearing-impaired mobile application to produce useable mobile application for the hearing-impaired. 2018 Thesis https://etd.uum.edu.my/9292/ https://etd.uum.edu.my/9292/1/Depositpermission-not%20allow_s900538.pdf text eng staffonly https://etd.uum.edu.my/9292/2/s900538_01.pdf text eng staffonly https://etd.uum.edu.my/9292/3/s900538_02.pdf text eng staffonly https://etd.uum.edu.my/9292/4/s900538_references.docx text eng public other doctoral Universiti Utara Malaysia
