This thesis project describes a system to make presentations more collaborative, consisting on a mobile application using mesh technology.The mesh network may be set up through the choreography of interaction created by attendees tapping their phones together at the start of the meeting. The fluid workflow for requesting and handing over control of the projector encourages sharing and makes the interaction between presenter and audience more collaborative.The design was evaluated through a collaborative session that pointed at several future lines of work. Furthermore, we found opportunities to leverage the use of mesh networks in the workplace.Finally, we carried out two explorations of the use of projectors and movement capture for the creation of visual content. This, along with the previous work, served as a base for the argument that there is an opportunity to discover rich interaction possibilities in the combination of small, modular IoT devices to create augmented spaces.

This research project is part of the Internet of Things and People (IoTaP) project at Malmo ̈ University. The project focuses on the aspects of human-computer interaction in a visual programming environment. Visual programming is becoming increasingly popular in different sector of the IT world. Visual programming allows for novices or non-professional programmers to create systems without any or extensive scripting/coding skills. The research presented in this thesis is on a visual rapid prototyping environment that is founded on an existing smart home platform, and allows for designers and developer to prototype smart home concepts using smart devices. The research methodologies used involve Design Science methods infused with User-Centered Design principles and methods (Participatory Design). The research process involves a series of workshops performed with some of the IoTaP smart home re- searcher. The research process also involves qualitative investigation of existing visual prototyping tools and techniques.A prototype of a visual rapid prototyping environment was used to evaluate the research findings. The evaluation process focused on defining the benefits of a visual rapid prototyping environment and how it can help improve the design and testing process of smart home devices.

Recent advances in the field of Internet of Things (IoT) are placing its own vision, as a platform of interconnected services and devices, at the heart of the smart home concept. This consolidation promises a new wave of innovative products designed in the open, and in which the user takes center stage starting from the very first steps. Therefore, researchers as well as product designers in these increasingly related fields are now tasked with a more complex mission when investigating user behavior. In this thesis we consider rapid prototyping as the upcoming standard process for investigating user interactions in the future smart home. Although past research contributed with several self-contained solutions (built from scratch) to allow such investigations, no accounts were found tackling the problem from our perspective, in which the focus is on how to enable rapid prototyping in an existing proprietary smart home platform by using open standards, software and hardware. To answer this question, we conducted our research with participation of academic researchers and professional designers in the context of an academic and industrial partnership, in an ongoing smart home research project. We used an approach based on the design science research process in combination with the user centered design (UCD) and agile software development methodologies. During this thesis we performed an end to end design process starting from ideation to implementation and evaluation; an architectural blueprint was proposed and a working prototype of our visual smart home rapid prototyping environment (SHRPE) was implemented and tested. The obtained results demonstrate the feasibility of enabling visual rapid prototyping capabilities in an existing smart home platform, by using the system integration process to introduce available open standards, software and hardware tools into the platform. In addition, evaluation results of user testing confirmed that using UCD to iteratively capture user needs in such complex context is a solid approach.
