“…It defines usability as a measure of the effectiveness and efficiency that users obtain from a product, as well as the satisfaction they feel about it. More broadly, UX is an umbrella term used to define many concepts that can also include usability (Majrashi et al 2015). It also considers user perceptions and responses from both the use and anticipated use of a product (ISO 2010).…”

This paper reports the development of a specialized teleguidance-based navigation assistance system for the blind and the visually impaired. We present findings from a usability and user experience study conducted with 11 blind and visually impaired participants and a sighted caretaker. Participants sent live video feed of their field of view to the remote caretaker’s terminal from a smartphone camera attached to their chest. The caretaker used this video feed to guide them through indoor and outdoor navigation scenarios using a combination of haptic and voice-based communication. Haptic feedback was provided through vibrating actuators installed in the grip of a Smart Cane. Two haptic methods for directional guidance were tested: (1) two vibrating actuators to guide left and right movement and (2) a single vibrating actuator with differentiating vibration patterns for the same purpose. Users feedback was collected using a meCUE 2.0 standardized questionnaire, interviews, and group discussions. Participants’ perceptions toward the proposed navigation assistance system were positive. Blind participants preferred vibrational guidance with two actuators, while partially blind participants preferred the single actuator method. Familiarity with cane use and age were important factors in the choice of haptic methods by both blind and partially blind users. It was found that smartphone camera provided sufficient field of view for remote assistance; position and angle are nonetheless important considerations. Ultimately, more research is needed to confirm our preliminary findings. We also present an expanded evaluation model developed to carry out further research on assistive systems.

“…In the context of the proliferation of computing devices and their rapid adoption by people, many terms emerged to describe interactive systems accessible through multiple platforms. The term 'crossplatform service' is used to describe "a set of user interfaces (UIs) for a single service encompassing two or more computational platforms for interacting with the service" (Majrashi, 2016;Majrashi, Hamilton, & Uitdenbogerd, 2015). The term 'multiple user interfaces' (MUIs) is also used to describe views of the same information and services accessed by users from different platforms (Nilsson, 2006;Samaan & Tarpin-Bernard, 2004;Seffah & Javahery, 2005).…”

Inter-platform consistency is a central inter-usability attribute in cross-platform service design. However, limited studies have investigated the importance of the different characteristics of inter-platform consistency for user experience (UX) of cross-platform services. A discounted, easy, fast inter-platform inspection method for cross-platform service design is still unavailable. In this paper, the authors present the results of a study on inter-platform service consistency using a new inspection method. Three UX experts evaluated three cross-platform services using predefined inter-platform consistency heuristics (perceptual, lexical, operational, and compositional). The evaluation yielded 287 inter-platform consistency findings (194 negative and 93 positive). The results indicated that all predefined consistency heuristics that represent inter-platform consistency characteristics are important and should be considered when designing the UX of cross-platform services. The evaluators assessed our inspection method and found it appropriate and effective.

“…These represent a broad cross section of activities performed on all platforms. In a separate study Majrashi, Hamilton and Uitdenbogred indicate that one of the main issues to be addressed before defining cross-platform usability is defining usability metrics [4]. Following this model, we have defined metrics of performance which can be used to measure user performance for each task.…”

“…However, these research studies focus on user satisfaction and they neglect other aspects of usability, putting an emphasis on qualitative over quantitative data. Understanding both qualitative and quantitative data can significantly enhance understanding of the complete user experience [4].…”

“…Usability is measurable by defined metrics such as time taken and number of errors while the computing task is performed. User satisfaction is measured by observation, surveys, diaries, interviews and similar instruments [4,10]. Waljas et al [10], Sahar et al [8] and others, in their studies of cross platform user experience have focused on the satisfaction of user experience by documenting diaries and interviews with participants.…”

This shift in computing expectations focuses on the ability to compute horizontally, performing the same tasks within different computing environments, as opposed to vertically, performing different tasks in the same computing environment. In this paper, we propose a method by which the usability of a given piece of software can be comparatively analyzed across all hardware platforms on which it is available. This methodology is based on the Majrashi and Hamilton's twelve factors of usability and has been extended to include specific applications and metrics for the following computing platforms: desktop computers, laptops, tablets, smartphones.These metrics focus on collecting quantitative data about the usability of each platform. This quantitative data contrasts with recent studies which focus extensively on qualitative data regarding the user experience. Combining these two types of studies will allow researchers to capture a more comprehensive picture of software usability across computing platforms.The methodology has been validated by performing an initial study using the tasks and performance metrics across each of the defined computing platforms. The results from these initial tests have allowed us to make improvements to the testing methodology as well as some hypotheses for further testing. This proposed methodology, when used in conjunction with qualitative research, can provide a reliable approach for cross-platform usability analysis.Some considerations for educational design of cross platform methodology are discussed.
