Reducing Scanning Keyboard Input Errors with Extended Start Dwell-Time
(Journal article; Peer reviewed, 2018)Some individuals with reduced motor function rely on scanning keyboards to operate computers. A problem observed with scanning keyboards is that errors typically occur during the first group or first cell of a group. This ... -
A Reference Data Model to Specify Event Logs for Big Data Pipeline Discovery
(Lecture Notes in Business Information Processing;, Chapter; Peer reviewed; Conference object; Journal article, 2023)State-of-the-art approaches for managing Big Data pipelines assume their anatomy is known by design and expressed through adhoc Domain-Specific Languages (DSLs), with insufficient knowledge of the dark data involved in the ... -
Reference deployment models for eliminating user concerns on cloud security
(Journal article; Peer reviewed, 2010-06-17)Cloud computing has become a hot topic both in research and in industry, and when making decisions on deploying/adopting cloud computing related solutions, security has always been a major concern. This article summarizes ... -
Reflective Text Entry: A Simple Low Effort Predictive Input Method Based on Flexible Abbreviations
(Procedia Computer Science;67, Journal article; Peer reviewed, 2015-11-06)Users with reduced physical functioning such as ALS patients need more time and effort to operate computers. Most of the previous assistive technologies use prefix based predictive text input algorithms. Prefix based ... -
Regularity of twisted spectral triples and pseudodifferential calculi
(Journal of Noncommutative Geometry;, Journal article; Peer reviewed, 2019-03-13)We investigate the regularity condition for twisted spectral triples. This condition is equivalent to the existence of an appropriate pseudodifferential calculus compatible with the spectral triple. A natural approach to ... -
Regulatory Intermediaries: The Role of Interest Organizations in Supporting Web Accessibility Policy Implementation.
(Studies in Health Technology and Informatics;Volume 256: Transforming our World Through Design, Diversity and Education, Journal article; Peer reviewed, 2018)This article explores how interest organizations, including non-profit and commercial service providers, act as intermediaries to support the implementation of regulations for web accessibility. Web accessibility policies ... -
Rehabilitation and Product Design: Towards the Inclusion of People with Disabilities Through Interdisciplinary Collaboration
(Journal article; Peer reviewed, 2018)In low-GDP countries, such as Brazil, many older people and people with disabilities rely on the public health system for access to assistive devices, which are important to support them to live healthy and dignified lives. ... -
