The Usability Factors Of Lost Digital Legacy Icoict.Pdf, David M. Cook, Derani Nathasha Dissanayake, Kulwinder Kaur Jul 2019

The Usability Factors Of Lost Digital Legacy Icoict.Pdf, David M. Cook, Derani Nathasha Dissanayake, Kulwinder Kaur

The increased acquisition of digital objects over time has grown in the 21st century to represent objects of value as digital assets. Many people who plan their lives are unaware of the transfer and ownership challenges associated with digital legacy. This paper discusses the burden of digital legacy management and the need for regulatory reform in the transition of digital objects to digital assets. A study of thirty two (n=32) Australians over the age of 65 identified critical issues in the transfer, ownership, management and mobility of digital objects under legacy conditions.

Virtual Reality And Older Hands: Dexterity And Accessibility In Hand-Held Vr Control, David M. Cook, Derani N. Dissanayake, Kulwinder Kaur Apr 2019

Virtual Reality And Older Hands: Dexterity And Accessibility In Hand-Held Vr Control, David M. Cook, Derani N. Dissanayake, Kulwinder Kaur

Whilst the VR Headset has a sense of commonality with users, VR hand controllers are largely incongruent with each other. This paper examines the common ground between VR developments in the area of hand control devices. This paper looks at VR controllers through the lens of older people, specifically for the purpose of including people from any age in the opportunity to enjoy the benefits of VR experiences. This study uses Fitts’ Index of Difficulty to determine areas of concern in terms of dexterity and accessibility. The study recommends a standardized approach to agility and access in VR hand control …

Haptic Alternatives For Mobile Device Authentication By Older Technology Users, David M. Cook, Kulwinder Kaur Jul 2018

Haptic Alternatives For Mobile Device Authentication By Older Technology Users, David M. Cook, Kulwinder Kaur

Dr. David M Cook

Turing tests are used to secure the human interaction on the Internet. Tests such as CAPTCHA are based on visual or auditory recognition of symbols and are difficult to distinguish by elderly people. A study examining the consistency of a tactile feedback-based Turing test identified an alternative to mainstream tests. This approach examines the vibration-based sensitivity which is detectable through skin surfaces when used to touch the screen of a mobile device. The study concentrated on a range of rough, smooth, sticky and coarse textures as possible differentiators for swipe-based tactile authentication using mobile devices. This study examined the vibration-based …

The Efficacy Of Using Virtual Reality For Job Interviews And Its Effects On Mitigating Discrimination, David M. Cook, Rico Beti, Faris Al-Khatib Jul 2018

The Efficacy Of Using Virtual Reality For Job Interviews And Its Effects On Mitigating Discrimination, David M. Cook, Rico Beti, Faris Al-Khatib

Dr. David M Cook

Virtual reality (VR) is an emerging technology that has already found successful application in a variety of different fields, including simulation, training, education, and gaming. While VR technologies have been considered for use in recruitment practices, available research on the topic is limited. In all stages of the recruitment process, social categorization of job applicants based on ethnicity, skin color, and gender, as well as other forms of discrimination are contemporary issues. This study examined the efficacy of using virtual reality technology as part of job interview strategies and evaluated its potential to mitigate personal bias towards job applicants. The …

The Changing Values Of Digital Legacies: E-Books And The Challenges Of Data Mobility And The Perceived Value Of Books, Derani Nathasha Dissanayake, David M. Cook Oct 2016

The Changing Values Of Digital Legacies: E-Books And The Challenges Of Data Mobility And The Perceived Value Of Books, Derani Nathasha Dissanayake, David M. Cook

Dr. David M Cook

Digital Legacies in the form of e-Books represent a challenge for those who make direct comparisons to in-print paper books.  Digital legacies come in a variety of segments that are characterised in terms of their perceived value. Digital objects retain higher values when they are easily transferred from one person to another. The value of e-books is dependent upon the ability to access and re-read each e-book, and to make a comparison between an e-book and a paper copy of the same book. A qualitative study of 32 adults over the age of 65 in Australia revealed the difficulty in …

Birds Of A Feather Deceive Together: The Chicanery Of Multiplied Metadata, David M. Cook Dec 2013

Birds Of A Feather Deceive Together: The Chicanery Of Multiplied Metadata, David M. Cook

Dr. David M Cook

New Media conventions have fluttered along unforeseen flight paths. By combining sock-puppetry with the grouping power of metadata it is possible to demonstrate widespread influence through Twitter dispersion. In one nest there is a growing use of sock-puppetry accentuated by the exploitation of a social media that does not attempt to verify proof of identity. Created identities in their thousands can flock towards, and in support of, a single identity. They do so alongside legitimate accounts but in concert remain imperceptible within an overall group. In another nest there is the practise of homophily, captured through metadata, and used to …
