Further, user interface (UI) designers struggle to adapt their UIs to evolving user needs and preferences. In order to address these issues, we want to support end users in designing their own user interfaces. However, end-user UI design represents a major challenge, given that end users often lack the necessary design skills. We investigated how design recommendations might be used to address the research question on how to help end users during the UI design process? A first step towards answering this question is the analysis of how end users should best get recommendations about potential design improvements. We therefore conducted a survey on how end users would like to get design recommendations, whether they trust user- or machine-generated recommendations, and whether they agree that their interactions are tracked and shared in order to improve the recommendations. Based on the results of our survey, we present a set of design requirements for the integration of recommendations in end-user UI design tools.

This paper provides a detailed overview of existing DUI approaches and classify the different solutions based on the granularity of the distributed UI components, the supported interaction space as well as their support for the distribution of state. After the analysis of existing solutions, we discuss a DUI scenario and derive a number of requirements for end-user DUI development. We propose an approach where users can author their customised user interfaces based on a hypermedia metamodel and the concept of active components. We further discuss possibilities for the configuration and sharing of customised distributed user interfaces by end users where the focus is on an authoring rather than a programming approach.

We also witness a growing number of Internet of Things (IoT) devices, allowing digital user interfaces (UIs) to communicate with physical objects and vice versa through so-called hybrid user interfaces. There exist various solutions to manage adaptive, distributed or hybrid UIs. However, none of them covers all three aspects and users have to deal with multiple applications and configurations when developing adaptive distributed hybrid user interfaces. We introduce the eSPACE reference framework and conceptual model unifying the domains of adaptive, distributed and hybrid interfaces. While our reference framework has been inspired by the CAMELEON reference framework, the conceptual model is based on the Resource-Selector-Link (RSL) hypermedia meta-model. We propose an approach for adaptive distributed hybrid user interfaces where users can author their user interfaces based on the different levels of abstraction introduced by our reference framework. We further present a use case illustrating the extensibility, flexibility and reusability offered by our unified approach and discuss potential future work.

While most of these authoring tools have been realised based on existing metaphors and evaluated in subsequent user studies, there is no consensus on how to best enable end users to manage and interact with their devices, IoT objects and services. In order to establish some common guidelines for the development of cross-device and IoT authoring tools, we conducted an elicitation study exploring a user's mental model when defining cross-device interactions in IoT environments. Existing authoring solutions have further been checked for compliance with our guidelines and we developed a fully-compliant end-user authoring tool for cross-device and IoT applications. The presented guidelines may inform the design of new as well as the improvement of existing solutions and form a foundation for discussion, future studies and refinements within the HCI community.

We provide an overview of existing DUI approaches and classify the different solutions based on the granularity of the distributed UI components, location constraints as well as their support for the distribution of state. We propose an approach for user-defined cross-device interaction where users can author their customised user interfaces based on a hypermedia metamodel and the concept of active components. Furthermore, we discuss the configuration and sharing of customised distributed user interfaces by end users where the focus is on an authoring rather than programming approach.

Despite the fact that paper documents still form a significant part of our daily working activities, existing PIM systems usually support the organisation and re-finding of digital documents only. While physical document tracking solutions such as RFID- or computer vision-based systems are recently gaining some attention, they usually focus on the paper document tracking and offer limited support for re-finding activities. We present PimVis, a solution for exploring and re-finding digital and paper documents in so-called cross-media information spaces. The PimVis user interface enables a unified organisation of digital and paper documents through the creation of bidirectional links between the digital and physical information space. The presented personal cross-media information management solution further supports the extension with alternative document tracking techniques as well as augmented reality solutions. A formative PimVis evaluation revealed the high potential of fully integrated cross-media PIM solutions.
