Objective We searched for the application of usability in the literature with a focus on adoption, measurements employed, and demonstrated value. Five human factors domains served as a platform for our reflection, which included the last 20 years. Background As usability studies continue to accumulate, there has been only a little past reflection on usability and contributions across a variety of applications. Our research provides a background for general usability, and we target specific usability research subareas within transportation, aging populations, autistic populations, telehealth, and cybersecurity. Method “Usability” research was explored across five different domains within human factors. The goal was not to perform an exhaustive review but, rather, sample usability practices within several specific subareas. We focused on answering three questions: How was usability adopted? How was it measured? How was it framed in terms of value? Conclusion We found that usability is very domain specific. Usability benchmarking studies and empirical standards are rare. The value associated with improving usability ranged widely—from monetary benefits to saving lives. Thus, researchers are motivated to further improve usability practices. A number of data collection and interpretation challenges still call for solutions. Application Findings offer insight into the development of usability, as applied across a variety of subdomains. Our reflection ought to inform future theory development efforts. We are concerned about the lack of established benchmarks, which can help ground data interpretation. Future research should address this gap in the literature. We note that our findings can be used to develop better training materials for future usability researchers.
Abstract. Individuals with Autism Spectrum Disorders (ASD) often have difficulty recognizing emotional cues in ordinary interaction. To address this, we are developing a social robot that teaches children with ASD to recognize emotion in the simpler and more controlled context of interaction with a robot. An emotion recognition program using the Viola-Jones algorithm for facial detection is in development. To better understand emotion expression by social robots, a study was conducted with 11 college students matching animated facial expressions and emotionally neutral sentences spoken in affective voices to various emotions. Overall, facial expressions had greater recognition accuracy and higher perceived intensity than voices. Future work will test the recognition of combined face and voices.
Traditionally, digital communication at the Electronics Engineering Technology (EET) Level, has focused on using amplitude modulation, frequency modulation, sideband communications, wave guide, radar and so on. However, with the advancement in technology the skills required to evaluate, integrate, and administer networking equipment is considered important for an EET student.The popularity and acceptance of computer networking have created a need to provide students in Electronics Engineering Technology with a training course based on the aforementioned technology. Computer networking training can be introduced as an integrated approach to traditional communication topics and computer networking. In an effort to introduce students to computer networkbased communication, the Electronics Engineering program at Savannah State University and Savannah Technical College has developed a course in which emphasis is directed towards a balanced curriculum that includes topics both from traditional communication area and computer networking concepts. This paper includes the course outline and information for an innovative computer-networking laboratory. The laboratory facilities accommodate study of several computer networking hardware and software technologies.
In the last decade technological advancement has significantly altered the delivery of teaching and learning processes. As a result of these phenomenal changes, institutions of higher learning across the country have introduced and established electronic classroom in order to attain more effective and productive educational outcomes, especially for students with special needs and those at different learning levels. In order to achieve similar objectives/outcomes experienced in the traditional classroom, educational technology must be integrated into the entire process of teaching and learning so that it becomes compatible with the conventional classroom practices. The goal of technology is not to replace the traditional classroom but it may be utilized as another tool to enhance what is already established. These tools when used wisely and effectively can further refine and improve upon the methods employed in the traditional classroom. This paper discusses the findings of study a utilizing the Hybrid WebCT model that was implemented by the Civil and Electronics Engineering Technology faculty during the fall semester of 2005. It also presents the learning outcomes of the student population under study. It was concluded that majority (70%) of the students did not require any additional instruction using WebCT (Table I), 92% found it very useful, 80% stated that it was useful in communicating with the instructor, 62% could upload the assignments using WebCT, 72% experienced no technical difficulties and 60% did state that it enhanced their learning. Majority (82%) of the students stated that they found the tool beneficial and that it facilitated their ability to keep currency with course requirements.
