How much does expertise matter?

Yeliz Yesilada, Giorgio Brajnik, Simon Harper
2009 Proceeding of the eleventh international ACM SIGACCESS conference on Computers and accessibility - ASSETS '09  
This paper sets out to investigate the interplay between expert and non-expert evaluation by conducting a Barrier Walk through (BW) study with 19 expert and 51 non-expert judges.  ...  Finally, both effectiveness and reliability of the expert judges are significantly higher than non-expert judges.  ...  CONCLUSION & FUTURE WORK In this paper, we have presented a BW method study with 19 ex perts and 51 non-experts. This study shows that expertise matter.  ...

Development and trial of an educational tool to support the accessibility evaluation process

Christopher Bailey, Elaine Pearson
2011 Proceedings of the International Cross-Disciplinary Conference on Web Accessibility - W4A '11  
The tool has recently been trialled with a group of 38 undergraduate computing students studying an Accessibility and Adaptive Technologies module with the aim of assessing its reliability and accuracy  ...  The software incorporates a structured walkthrough approach to guide the auditor through a series of checks for established accessibility principles with the goal of conducting a comprehensive accessibility  ...  In an evaluation of the Barrier Walkthrough method with experts and non-experts [30] , it was concluded that the auditors' level of expertise is an important factor in the quality of an accessibility  ...

Human-Centric Development of Software Tools (Dagstuhl Seminar 15222)

Andrew J. Ko, Shriram Krishnamurhti, Gail C. Murphy, Janet Siegmund, Marc Herbstritt
2016 Dagstuhl Reports  
Over two and half days, over 30 participants engaged in inventing and evaluating programming and software engineering tools from a human rather than tool perspective.  ...  We discussed methods, theories, recruitment, research questions, and community issues such as methods training and reviewing. This report is a summary of the key insights generated in the workshop.  ...  However, existing studies were inconclusive. So, does layout matter? The Forgetting Curve In a series of experiments we found evidence that layouts do actually matter.  ...

Customized performance evaluation approach for Indian green buildings

Rajat Gupta, Matt Gregg, Sanyogita Manu, Prasad Vaidya, Maaz Dixit
2018 Building Research & Information  
As academia is considered to be an initial primary outlet of BPE, a survey of experts is conducted to investigate the drivers and barriers for implementing BPE-based methods in educational curricula.  ...  The expert survey reveals the lack of trained people for teaching BPE as a key challenge to its adoption, implying that trained people are needed as much as frameworks.  ...  Acknowledgement This study was undertaken as part of a Newton Fund UK-India research project on learning building performance evaluation (BPE) for improved design and engineering in India (Learn-BPE).  ...

2022 Proceedings of the 2022 ACM Conference on International Computing Education Research V.1  
Objective: To investigate this aspect of CS-ed's inclusivity, we conducted a three-phase field study with online CS faculty, with three research questions: (1) whether, how, and where online CSed's courseware  ...  has inclusivity bugs; (2) whether an automated tool can detect them; and (3) how online CS faculty would make use of such a tool.  ...  #2042324, and joint support by NSF and USDA-NIFA under #2021-67021-35344.  ...

A Cognitive Walkthrough towards an Interface Model for Shape Grammar Implementations

Joana Tching, Joaquim Reis, Alexandra Paio
2016 Computer Science and Information Technology  
This paper presents the description of the analysis used to define the IM-sgi model, with the result of a Cognitive Walkthrough (CW) made to a group of SG implementations and with the interaction model  ...  of Scott Chase [1] as the basis to define the users and how they communicate with the SG implementation.  ...  The model of interaction between SG and the user developed by Scott Chase [1] is a very good example of the studies on this matter.  ...

Why you need to include human factors in clinical and empirical studies ofin vitropoint of care devices? Review and future perspectives

Simone Borsci, Peter Buckle, George B. Hanna
2016 Expert Review of Medical Devices  
Whilst the literature confirms some advantages of bed-side tests compared to those in laboratories there is a lack of knowledge of the risks associated with their use.  ...  This article provides a review of approaches applied by clinical researchers to model the use of in-vitro testing. Results suggest that only a few studies have explored human factor approaches.  ...  The current limited application of HFE approaches in clinical and comparative studies results in a limited knowledge of how much POC devices may be bringing medical errors closer to the patients [18]  ...

Later on they were matched randomly to constitute a group of two and they were asked to revise their initial assessment and to produce a group assessment of the same page.  ...  Members of groups exhibited strong agreement on the evaluation results among them and with the group outcome. Other measures of validity and reliability are not significantly affected by group-work.  ...  For example, when considering the expertise effect on barrier walkthrough and WCAG 2.0 conformance review 1 it was found that expecting agreement at the 80% level, which was a level suggested for human  ...
