Purpose This paper aims to present a detailed description of Tukuchiy, a framework to dynamically generate adapted user interfaces. Tukuchiy is based on Runa-Kamachiy, a conceptual integration model that combines human–computer interaction (HCI) standards to create user interfaces with user-centered concepts usually addressed by adaptation. Design/methodology/approach The first step was the definition of three profiles: user, context and interface. These profiles contain information, such as user disabilities, location characteristics (e.g. illumination) and preferences (e.g. interface color or type of system help). The next step is to define the rules that ensure usability for different users. All of this information is used to create the Tukuchiy framework, which generates dynamic user interfaces, based on the specified rules. The last step is the validation through a prototype called Idukay. This prototype uses Tukuchiy to provide e-learning services. The functionality and usability of the system was evaluated by five experts. Findings To validate the approach, a prototype of Tukuchiy, called Idukay, was created. Idukay was evaluated by experts in education, computing and HCI, who based their evaluation in the system usability scale (SUS), a standard usability test. According to them, the prototype complies with the usability criteria addressed by Tukuchiy. Research limitations/implications This work was tested in an academic environment and was validated by different experts. Further tests in a production environment are required to fully validate the approach. Originality/value Tukuchiy generates adapted user interfaces based on user and context profiles. Tukuchiy uses HCI standards to ensure usability of interfaces that dynamically change during execution time. The interfaces generated by Tukuchiy adapt to context, functionality, disabilities (e.g. color blindness) and preferences (usage and presentation) of the user. Tukuchiy enforces specific HCI standards for color utilization, button size and grouping, etc., during execution.

A common problem in information systems development is to provide support for adaptation, to automatically adjust their services to different users and contexts. User Interfaces (UI) are required to adapt to those contexts and to satisfy specific criteria and standards to guarantee usability. Several methods have been created to ensure a degree of usability in UI. However, these methods focus mainly in the design stage of the development process. The benefits of these methods may be lost during execution time, since they do not address the necessity to dynamically adapt the interfaces both to context and users. To address this issue it is necessary to integrate User Interface Design with Adaptation, to ensure that UI usability is preserved at the execution time, for different users and contexts. This paper proposes the framework Tukuchiy, a rulebased system that dynamically generates Adaptative User Interfaces, based in HCI precepts. This guarantees their usability during execution time, while taking into account user preferences and context. This paper focused in the rule-based system of Tukuchiy. That rule system includes usability criteria commonly used for web pages, which were mapped to a desktop application.
