Current usability testing involves the collection of data that often lacks objectivity and seldom adheres to rigorous standards of quantitative research. Because such studies are characterized by subjective opinions of raters using Likert scales, they are often snared by many problems, not the least of which is rater reliability. This contribution presents a technological method for testing use...
This study aimed to describe narrative discourse productions of older language impaired learning disabled (LILD) children, using stringent reliability measures. Coherence and cohesion were the measures of analysis employed. Content and clarity ratings provided a subjective analysis of narrative productions. Interrater and intrarater reliability measures were calculated and testing for stability...
Subjective well-being changes over time. While the causes of these have been investigated extensively, few attempts made to capture through computational modelling. One notable exception is study by Rutledge et al. [Rutledge, R. B., Skandali, N., Dayan, P., & Dolan, J. (2014). A and neural model momentary subjective well-being. Proceedings National Academy Sciences, 111(33), 12252–12257. https:...
Usability testing is an important method for examining how system users understand and use a system to complete a specific task. This research method is used by system developers to test and evaluate automated tools ranging from information systems, web-based questionnaires, and websites. RTI International recently implemented a large-scale, multi-site usability testing effort to assist in the ...
This paper identifies a number of factors involved in current practices of usability testing and presents profiles for three prototype methods: think-aloud, subjective ratings, and history files. We then identify ideal levels to generate the profile for new methods. These methods involve either a human observer or a self-administration of the test by the user. We propose methods of automating t...
Usability engineering and usability testing are concepts that continue to evolve. Interesting research studies and new ideas come up every now and then. This paper tests the hypothesis of using an EDA-based physiological measurements as a usability testing tool by considering three measures; which are observers’ opinions, self-reported data and EDA-based physiological sensor data. These data we...
Apparently on the basis of room modes being excited in residential dwellings one concept has been to ignore high quality field measurement recordings (Wave files) and use the narrow band (FFT) Leq results of a 10-minute sample to create, by superimposing a number of sine waves, a trapezoidal time signal as the source for subjective testing and restricting the bandwidth to only infrasound. Other...
We describe a Telerehabilitation system that has been developed in our laboratory. The system allows a therapist in a remote location to conduct treatment sessions, using a virtual environment based motor training system, with a patient who is located at home. The design, technical testing and clinical feasibility testing of the system are reported. Results from the first two stroke patients to...
The cause of Lyme disease, Borrelia burgdorferi, was discovered in 1983. A 2-tiered testing protocol was established for serodiagnosis in 1994, involving an enzyme immunoassay (EIA) or indirect fluorescence antibody, followed (if reactive) by immunoglobulin M and immunoglobulin G Western immunoblots. These assays were prepared from whole-cell cultured B. burgdorferi, lacking key in vivo express...
Software testing is one of the most important phases in the Software Development Life Cycle (SDLC) which helps in assessing the quality of the software. There are a number of testing techniques at various phases of testing. Selection of the right testing technique at any stage is one of the critical problems and depends on many factors such as resources, schedule, cost of the project, etc. The ...
