A Novel Mobile Wallet Model for Elderly Using Fingerprint as Authentication Factor

et al. 2020

Due to the availability of fingerprint verification technology on mobile devices fingerprint based human identification has become the most widely used biometric technology in everyday life. The elderly find digital payment applications difficult to operate and unsecure. This work has exploited fingerprint verification availability on mobile devices to provide a user friendly and secure digital wallet payment facility to elderly who are unable to avail this facility due to the complex infrastructure of traditional authentication mechanisms. A novel digital payment mechanism is presented which uses Bluetooth technology of mobile devices for billing at the point of sale and fingerprint verification for user authentication. A proof of the concept study is presented to validate the proposed model using state of the art usability questionnaires and attributes with the target group. The result indicates that the proposed methodology provides satisfaction and ease of use to the user.

“…Lazar argues that each group has its own unique cognitive traits and thus its own sets of strengths and weaknesses. Cortés et al [14] analysed the usability of applications that are used by children, however the general recommendations focus more on software programming than on the hardware itself. Feng [9] studied the use of computers by adolescents and children, observing that although children encountered problems interacting with these primarily as a result of the software not being designed for their specific needs, results gathered from expert users shows that, with practice, teenagers gain the skills needed to work with word processing, data entry, and communication software [15].…”

Hand Gestures in Virtual and Augmented 3D Environments for Down Syndrome Users

et al. 2019

Studies have revealed that applications using virtual and augmented reality provide immersion, motivation, fun and engagement. However, to date, few studies have researched how users with Down syndrome interact with these technologies. This research has identified the most commonly used interactive 3D gestures according to the literature and tested eight of these using Oculus, Atheer and Leap Motion technologies. By applying MANOVAs to measurements of the time taken to complete each gesture and the success rate of each gesture when performed by participants with Down syndrome versus neurotypical participants, it was determined that significant difference was not shown for age or gender between these two sample groups. From the results, a difference was only demonstrated for the independent variable Down syndrome when analysed as a group. By using ANOVAs, it was determined that both groups found it easier to perform the gestures Stop, Point, Pan and Grab; thus, it is argued that these gestures should be used when programming software to create more inclusive AR and VR environments. The hardest gestures were Take, Pinch, Tap and Swipe; thus, these should be used to confirm critical actions, such as deleting data or cancelling actions. Lastly, the authors gather and make recommendations on how to develop inclusive 3D interfaces for individuals with Down syndrome.

“…Rarely do children who have begun walking (which is frequently delayed by an average of 12-18 months) continue to get physiotherapy [35]. But multiple reports in the literature indicate that children with DS start having orthopedic issues in their early years and would benefit from specialized biomechanical evaluation and care [11], [27], [40].…”
