As the popularity of Smart Televisions (TVs) and interactive Smart TV applications (apps) has recently grown, the usability of these apps has become an important quality characteristic. Previous studies examined Smart TV apps from a usability perspective. However, these methods are mainly manual, and the potential of automated model-based testing methods for usability testing purposes has not yet been fully explored. In this paper, we propose an approach to test the usability of Smart TV apps based on the automated generation of a Smart TV user interaction model from an existing app by a specialized automated crawler. By means of this model, defined user tasks in the Smart TV app can be evaluated automatically in terms of their feasibility and estimated user effort, which reflects the usability of the analyzed app. This analysis can be applied in the context of regular users and users with various specific needs. The findings from this model-based automated analysis approach can be used to optimize the user interface of a Smart TV app to increase its usability, accessibility, and quality.

“…Here we have demonstrated that formal techniques may be used to verify these risk control measures. The process of proving regulatory requirements has been discussed in more detail in [44], [45]. This process is typically interactive and in principle involves discussion with both human factors specialists, who are engaged in checking the validity of the interpretation of the user-related requirement, and regulator to check that the property captures the spirit of the original requirement.…”

The paper describes templates for model-based analysis of usability and safety aspects of user interface software design. The templates crystallize general usability principles commonly addressed in user-centred safety requirements, such as the ability to undo user actions, the visibility of operational modes, and the predictability of user interface behavior. These requirements have standard forms across different application domains, and can be instantiated as properties of specific devices. The modeling and analysis process is carried out using the Prototype Verification System (PVS), and is further facilitated by structuring the specification of the device using a format that is designed to be generic across interactive systems. A concrete case study based on a commercial infusion pump is used to illustrate the approach. A detailed presentation of the automated verification process using PVS shows how failed proof attempts provide precise information about problematic user interface software features.

“…An approach to the verification of user interfaces based on a combination of theorem proving and model checking is presented in [15]. In particular, [15] focuses on the problem of how to demonstrate that a software design is compliant with safety requirements (e.g., certain FDA guidelines). Their solution is elegant in their combined use of model checking, theorem proving, and simulation within one framework.…”

“…Their solution is elegant in their combined use of model checking, theorem proving, and simulation within one framework. A difference to our work is that [15] verifies models of devices while we verify the software (e.g., handlers of GUI events) directly. Furthermore, we allow the verification of GUI software with an infinite number of states which is not the focus of [15].…”

Although there have been major achievements in verified software, work on verifying graphical user interfaces (GUI) applications is underdeveloped relative to their ubiquity and societal importance. In this paper, we present a library for the development of verified, statedependent GUI applications in the dependently typed programming language Agda. The library uses Agda's expressive type system to ensure that the GUI, its controller, and the underlying model are all consistent, significantly reducing the scope for GUI-related bugs. We provide a way to specify and prove correctness properties of GUI applications in terms of user interactions and state transitions. Critically, GUI applications and correctness properties are not restricted to finite state machines and may involve the execution of arbitrary interactive programs. Additionally, the library connects to a standard, imperative GUI framework, enabling the development of native GUI applications with expected features, such as concurrency. We present applications of our library to building GUI applications to manage healthcare processes. The correctness properties we consider are the following: (1) That a state can only be reached by passing through a particular intermediate state, for example, that a particular treatment can only be reached after having conducted an X-Ray. (2) That one eventually reaches a particular state, for example, that one eventually decides on a treatment. The specification of such properties is defined in terms of a GUI application simulator, which simulates all possible sequences of interactions carried out by the user.
