Prototyping and Evaluation of an Interactive DoorSign Aufbau und Evaluierung eines interaktiven Türschildes

Optimized usage of rooms at university becomes more and more important with a growing number of students. As a student today it is close to impossible to reserve a room for learning. Of course there are rooms known to be available at a certain time, but these can not be booked by students so there is the possibility that you and your learning group will compete with some noisy group of other students who occupied the room as well. To improve that situation the Interactive DoorSign, a prototype developed to manage rooms through an Android tablet attached next to them, was put into beta testing. There are existing projects on the topic which were reviewed in chapter 2. The improvements on the existing concept and development required to put the prototype into testing are described as well, especially the casing that was assembled using rapid prototyping technology is unusual. Details of the security implications, the possible attack vectors on the system and the concerns about the privacy of the users are discussed in chapter 3. The evaluation of the prototype can be found in chapter 4 and 6. The methodology of the evaluation is described. The results show that while the prototype implementation receives a low value on the System Usability Scale (SUS) every user was able to complete the given tasks and was able to learn the interaction with the system quickly.
