This paper describes the creation of a problem-based learning unit. The aim is to help students to learn how to make applications more accessible through aspects of personalization. In addition, a basic understanding of smarthome interfaces will be given. For this purpose, the personalization framework OpenAPE and the smarthome interface OpenHAB will be used. A java OpenAPEClient will be created for OpenAPE. The client will then be used in a tutorial application. This tutorial application is to be integrated as a kind of cloze text in the learning unit as a practical exercise. It implements a lamp control and a personalizable user interface. Final user tests showed that the learning unit is executable as planned. Some problems and inconsis tencies were already identified and eliminated during the user tests.

This learning units teaches the concepts of Universal Design and Persona lization in the context of smart homes. Practical assignments include the study of personas with disabilities, and the specification of preference pro files for users with disabilities, using the OpenAPE framework notation (based on ISO/IEC 24752-8).

Experimentation in the laboratory plays an important role in students' education in order to acquire the necessary practical knowledge. However, this laboratory experience cannot be offered to all students due to various reasons, such as expensive equipment, limited access, or insufficient capaci ty. For this reason, virtual labs have been gaining interest for several years to make lab work more accessible. This paper is dedicated to this topic, showing the possibilities and highlighting the important role of virtual labs in education. However, there is a lack of didactically and qualitatively sophisticated digital solutions in many areas. With a case study, this paper aims to extend the state of research around virtual labs and investigate the feasibility of virtualizing a smart home lab. In addition to the design phase, in which the requirements for the solution are elaborated, the implementa tion of the virtual lab with suitable technologies as well as the evaluation of the application with the help of user tests is presented. The results show that the virtual PUX lab is seen as a useful alternative to the real lab. The identi fied weaknesses from the user tests could be used to further improve the prototype for its integration into the DigiLab4U platform and its productive application in lectures and workshops.
