Abstract
This paper briefly describes how property templates have been used to analyse and explore the interactive behaviour of a specific medical device (an IV infusion pump). It is proposed that interactive devices that satisfy properties based on the templates are easier and safer to use. The property templates act as heuristics for the development of suitable properties tailored to the details of the particular device. A mathematically based approach is used to prove that a specification of the device satisfies the properties. Copyright © 2015 ICST.

Abstract
Background: Due to their different propagation times, visual and auditory signals from external events arrive at the human sensory receptors with a disparate delay. This delay consistently varies with distance, but, despite such variability, most events are perceived as synchronic. There is, however, contradictory data and claims regarding the existence of compensatory mechanisms for distance in simultaneity judgments. Principal Findings: In this paper we have used familiar audiovisual events - a visual walker and footstep sounds and manipulated the number of depth cues. In a simultaneity judgment task we presented a large range of stimulus onset asynchronies corresponding to distances of up to 35 meters. We found an effect of distance over the simultaneity estimates, with greater distances requiring larger stimulus onset asynchronies, and vision always leading. This effect was stronger when both visual and auditory cues were present but was interestingly not found when depth cues were impoverished. Significance: These findings reveal that there should be an internal mechanism to compensate for audiovisual delays, which critically depends on the depth information available.

Abstract
Applying model-based testing to interactive systems enables the systematic testing of the system by automatically simulating user actions on the user interface. It reduces the cost of (expensive) user testing by identifying implementations errors without the involvement of human users, but raises a number of specific challenges, such as how to achieve good coverage of the actual use of the system during the testing process. This paper describes TOM, a model-based testing framework that uses a combination of tools and mutation testing techniques to maximize testing of user interface behaviors.

Abstract
User experience is a key point for successful ubiquitous computing (ubicomp) environments. The envisaged design should be explored as soon as possible to anticipate potential user problems, thus reducing re-design costs. The development of ubicomp environments' prototypes might help, providing feedback on the users' reaction to the environments. This paper describes the design and evaluation of ubicomp environments using APEX, a rapid prototyping framework providing user experience via a 3D application server and connected physical devices. APEX prototypes allow users to explore and experience many characteristics of a proposed design, in a virtual world. The paper focus in particular the design and evaluation of a smart library in the APEX framework. © 2014 Springer International Publishing Switzerland.

Abstract
Many aspects of the human experience of ubiquitous computing in built environments must be explored in the context of the target environment. However, delaying evaluation until a version of the system can be deployed can make redesign too costly. Prototypes have the potential to solve this problem by enabling evaluation before actual deployment. This paper presents a study of the design space of immersive prototyping for ubiquitous computing. It provides a framework to guide the alignment between specific evaluation goals and specific prototype properties. The goal is to understand the potential added-value of 3D simulation as a prototyping tool in the development process of ubiquitous computing environments. © 2013 Springer-Verlag.

Abstract
We have developed a framework to support adaptive elements in Web pages. In particular we focus on adaptive menus. Developers are able to define rules for menu adaptation according to the features of the device and browser in use. This paper briefly describes the selected adaptation patterns and their implementation. © Springer International Publishing Switzerland 2014.
