In order to ensure usability, it is necessary to schedule activities and methods to be applied throughout different stages of the development process. There exists a substantial number of usability methods to be applied in user-centered software development. However, the application of each usability method largely depends on specific constraints that should be closely considered. Even so, these constraints are not always known beforehand, remaining unidentified or under uncertainty at early stages of the project. Objective: This paper presents an approach to automatically recommend 43 usability methods depending on the project's stage and constraints. Our approach deals with uncertainty to recommend usability methods regardless of the completeness of the information available, which makes it suitable for enhancing initial scheduling. Besides, a supporting tool intended to schedule and guide on usability methods is presented in order to systematize the recommendation mechanism. Method: To validate our approach, we present two application scenarios demonstrating the suitability of the mechanism, including also an expert analysis to observe the recommendation appropriateness in terms of recommendation gap. Also, a user testing was accomplished to evaluate the usability of the approach with key users. Results: A low recommendation gap was observed (< 2.5%) and, according to the results obtained in the user testing, high percentage values for usefulness (82.38%) and satisfaction (87.89%) were obtained. The user evaluation also reported high values concerning other dimensions such as ease of use (89.00%) and ease of learning (92.38%). Conclusions: Results obtained helped answer main research questions, demonstrating that it is possible to create a mechanism to recommend usability methods according to a software project's constraints, even under uncertainty, and also affirm that it is possible to systemize the recommendations with a scheduling tool being satisfactory for key stakeholders, denoting acceptable levels of recommendation appropriateness, usefulness, and overall usability.

“…Maturity levels are the most applied in industry organizing the process areas in a staged representation where each level is composed of several process areas. The staged representation has five maturity levels (1)(2)(3)(4)(5). Process areas of engineering are in the Defined level (3), which means the organization uses a defined process to develop its systems.…”

“…With all the identified citations and considering the literature of HCI (for example, [3,11,12]) and existing reviews of HCI approaches that support system development (for example, [4,5,13]), we proposed an initial set of approaches organized in 10 HCI categories. For each HCI category, we included examples of methods, techniques, and standards.…”

Human-Computer Interaction (HCI) community has proposed many methods, techniques and standards for the development of interactive systems. Despite the great recognition of many of these approaches in academia, little is known about the state of practice in industry. To what extent are they known and used, while using a defined software process, to develop interactive systems? What is their level of use compared to software engineering approaches? This paper presents a study that we have conducted to answer these questions.

“…potential end users from the target groups are continually involved in the development. We determined the appropriate usability methods using a semi-automated approach based on ISO/TR 16982 [15] which implements propositions from [16]. Analyses of the contexts of use in the workshop and the retirement home, as well as task analyses were conducted in order to identify feasible sequences of actions (cp.…”

In this paper, we describe the assistive system ADAMAAS (Adaptive and Mobile Action Assistance) introducing a new advanced smartglasses technology. The aim of ADAMAAS is to move from stationary status diagnosis systems to a mobile and adaptive action support and monitoring system, which is able to dynamically react in a context sensitive way to human error (slips and mistakes) and to provide individualized feedback on a transparent virtual plane superimposed on user's field of view. For this purpose ADAMAAS uses advanced technologies like augmented reality (AR), eye tracking, object recognition, and systematic analysis of users' mental representations in long term memory. Preliminary user tests with disabled participants at an early prototype stage revealed no substantial physical restrictions in the execution of their activities, positive feedback regarding the assistive hints, and that participants could imagine wearing the glasses for long periods of time.
