User Acceptance of ‘Let’s Talk Now’ Mobile App for Dysarthric Children

Abstract

<p class="SPIEabstractbodytext">Dysarthria is a neurological disorder that damages of motor speech articulation.Young children who suffered from this disorder have no problem with their cognition, but they have difficulties to speak out their words. They could not have an accurate and smooth communication with their family and friends due to this disorder. Therefore, the purpose of this study is to investigate the user acceptance of an interactive speaking tool in the form of a mobile application named 'Let's Talk Now' which was designed with redundant multimedia elements for the use of dysarthric children aged 3 to 7 years old. This mobile appwas designed and developed as an early intervention to help the dysarthric who are facing problem to communicate and enable them to be understood by others. It focuses on daily usable conversation terms for family, greeting and expressions, places, ordering food and beverages, activities and asking for help. This study involved 15 respondents who are related to dysarthria namely therapists, parents, and teacher of dysarthric children. The 'Let's Talk Now' mobile app’s acceptance was evaluated using the USE (Usefulness, Satisfaction and Ease of Use) Questionnaire (Lund, 2001) which was used to measure its user acceptance. The findings described that all of the respondents agreed that the 'Let's Talk Now' mobile app is usable and suitable in helping the communication between dysarthric children and people.</p>

Development of a Fuzzy Model and Usability Test of a Recommended Interface Design for Mobile Phones for Elderly Users

“…Harum et al, for instance, have used AI technology and smartphone application technology such as the Digital Daisy Book Reader to develop a multi-language interactive book reading device that can be used by the visually impaired to 'read' information in public places [24]. Conversely, mobile apps for smartphones are increasingly being developed to help users manage a huge range of human needs, from finding ways for dysarthic children (children with a neurological disorder that damages their ability to speak) to communicate using 'daily usable conversation terms' [25], to encouraging inveterate online texters to find more polite ways of communicating [26]. Mobile phones are being developed as 'fall detection system' sensors 'trained' to detect 'falling in any direction' from common activities such as walking or jogging [27].…”
