Design and Implementation of Post-WIMP Distributed User Interfaces with ZOIL

"Interactive spaces" are physical environments or rooms for collaborative work that are augmented with ubiquitous computing technology. Their purpose is to enable a computer-supported collaboration between multiple users that is based on a seamless use of different devices for natural "post-WIMP" interaction (e.g., multitouch walls, interactive tabletops, tablet PCs, or digital pen and paper). However, to this day, there are no well-established guidelines or toolkits for designing and implementing such distributed user interfaces (DUIs). Therefore, this article introduces the Zoomable Object-Oriented Information Landscape (ZOIL), a novel design approach and software framework for post-WIMP DUIs in interactive spaces.In the following, the ZOIL design principles are first introduced and illustrated. They provide recommendations and examples of DUI interaction design for interactive spaces. Then the different software patterns and architectures that have been employed for implementing the open-source ZOIL software framework are described. This framework facilitates the implementation of ZOIL's design principles in practice. Lessons learned from ZOIL's implementation are shared, and the implementation is discussed and compared with related work and approaches. The results of an evaluation of ZOIL with designers and developers conclude the article

Proceedings of Cross-Surface 2016: Workshop on Challenges and Opportunities for 'Bring-Your-Own-Device' (BYOD) in the Wild

In this workshop, we reviewed and discussed challenges and opportunities for Human-Computer Interaction in relation to cross-surface interaction in the wild based on the bring-your-own-device (BYOD) practice. We brought together researchers and practitioners working on technical infrastructures for cross-surface computing, studies of cross-surface computing in particular domains as well as interaction challenges for introducing cross-surface computing in the wild, all with a particular focus on BYOD. Examples of application domains are: cultural institutions, work places, public libraries, schools and education. Please find more details about the workshop, in the submitted proposal [1]. The workshop was held in conjunction with the 2016 ACM Conference on Human Factors in Computing Systems (CHI), that took place from May 7 to 12 in San Jose, USA.

Enhanced visualisation techniques to support access to personal information across multiple devices

The increasing number of devices owned by a single user makes it increasingly difficult to access, organise and visualise personal information (PI), i.e. documents and media, across these devices. The primary method that is currently used to organise and visualise PI is the hierarchical folder structure, which is a familiar and widely used means to manage PI. However, this hierarchy does not effectively support personal information management (PIM) across multiple devices. Current solutions, such as the Personal Information Dashboard and Stuff I’ve Seen, do not support PIM across multiple devices. Alternative PIM tools, such as Dropbox and TeamViewer, attempt to provide a means of accessing PI across multiple devices, but these solutions also suffer from several limitations. The aim of this research was to investigate to what extent enhanced information visualisation (IV) techniques could be used to support accessing PI across multiple devices. An interview study was conducted to identify how PI is currently managed across multiple devices. This interview study further motivated the need for a tool to support visualising PI across multiple devices and identified requirements for such an IV tool. Several suitable IV techniques were selected and enhanced to support PIM across multiple devices. These techniques comprised an Overview using a nested circles layout, a Tag Cloud and a Partition Layout, which used a novel set-based technique. A prototype, called MyPSI, was designed and implemented incorporating these enhanced IV techniques. The requirements and design of the MyPSI prototype were validated using a conceptual walkthrough. The design of the MyPSI prototype was initially implemented for a desktop or laptop device with mouse-based interaction. A sample personal space of information (PSI) was used to evaluate the prototype in a controlled user study. The user study was used to identify any usability problems with the MyPSI prototype. The results were highly positive and the participants agreed that such a tool could be useful in future. No major problems were identified with the prototype. The MyPSI prototype was then implemented on a mobile device, specifically an Android tablet device, using a similar design, but supporting touch-based interaction. Users were allowed to upload their own PSI using Dropbox, which was visualised by the MyPSI prototype. A field study was conducted following the Multi-dimensional In-depth Long-term Case Studies approach specifically designed for IV evaluation. The field study was conducted over a two-week period, evaluating both the desktop and mobile versions of the MyPSI prototype. Both versions received positive results, but the desktop version was slightly preferred over the mobile version, mainly due to familiarity and problems experienced with the mobile implementation. Design recommendations were derived to inform future designs of IV tools to support accessing PI across multiple devices. This research has shown that IV techniques can be enhanced to effectively support accessing PI across multiple devices. Future work will involve customising the MyPSI prototype for mobile phones and supporting additional platforms

A practice-based exploration of natural environment design in computer & video games : volume 1

I offer this thesis as an original and substantial contribution to knowledge in virtual natural environment design practice within computer and video games, by identifying areas of strong/weak practice and to develop a new design framework that utilises a cross-disciplinary approach for practitioners/students/researchers. The thesis combines theoretical frameworks as well practical guidance within a new design framework for virtual natural environment design.The themes relating to this work were examined through a contextual review that focused on previous professional practice as well as critical games produced during the last 30 years. The contextual review involved a detailed textual and visual-based historical survey of virtual landscapes, resulting in a practice-based exploration of virtual natural environment design in computer and video games. One of the main artefacts produced in this research, a three-volume book series titled Virtual Landscapes, presents for the first time these virtual spaces in a digitally enhanced manner through high-resolution panoramic imagery. A review of existing literature and current practice revealed that virtual natural environment design has so far been driven by mainly aesthetic principles and hinted that future emergent design practice should involve a cross/multi-disciplinary approach. The research proposes a new design framework for the creation of virtual landscapes that uses Landscape Character Assessments amongst other elements of environmental design. ShadowMoss Island is a practice-based exploration of how virtual natural environmental design can incorporate elements from Environmental Psychology and Geology, as well as personal reflections and observational analysis based on a field trip. The research proposes that psychological elements added to this new design framework can radically improve the success and impact of the final virtual natural environment.Another practice-based artefact, MindFlow, was created as a pre-production tool for the purpose of environmental design. The proposed tool enables the direct visualisation of collated multimedia (audio, images, video, annotations, design and decisions) in much more natural setting of a single visual space, allowing designers/artists to draw and influence the design and creation of virtual natural environments by bringing together all the different aspects in an intuitive and user-friendly manner. MindFlow helps solve the problem of designers/artists having to retain mental maps of image repositories structure by creating a single visual non-folder tree hierarchy virtual space. The research has significance to both professional and pedagogic practitioners working in the area of computer and video game natural environment design
