Drawings as Input for Handheld Game Computers

The Nintendo DS (TM) is a hand held game computer that includes a small sketch pad as one of it input modalities. We discuss the possibilities for recognition of simple line drawing on this device, with focus of attention on robustness and real-time behavior. The results of our experiments show that with devices that are now becoming available in the consumer market, effective image recognition is possible, provided a clear application domain is selected. In our case, this domain was the usage of simple images as input modality for computer games that are typical for small hand held devices

ARCHITECTURAL HYPER-MODEL: CHANGING ARCHITECTURAL CONSTRUCTION DOCUMENTATION

More architects and spatial designers are producing complex 3D computer models as part of their everyday design process and documentation than ever before. Parallel to this shift, there has been a rapid rise in consumer computer processing power that has made hyper realistic digital environments a part of our home entertainment. Together, the 3D CAD models and the Computer Gaming Engine could become an architectural hyper-model that renders a digital environment in real time. Such a model would enable users to navigate freely, effectively establishing a new mode of reading space that hovers between 2D drawings and a real space.(Nitsche & Roudavski). This paper will examine how these worlds can merge to form an architectural hyper-model as a valuable supplement to the more conventional scaled 2D construction drawing documentation found on construction sites. While easily misconstrued as speculative, the ideas presented in this paper outline an on-going body of innovative research currently at the prototype stage. These prototypical hyper-models explore the possibilities of providing construction workers and project mangers access to an architect’s 3D computer models on site. These models originate from within conventional building construction drawings such as detailed sections and exploded axonometrics. A process of reinterpretation occurs to locate these drawings and their information within an interactive 3D space. Such operations take advantage of the best of both paradigms. This gives users access to, and control of, the 3D information required for communicating necessary information about the building process. It also provides nodes or hyper-links in the 3D representation that connect to additional information, such as specifications, that are perhaps less formal/spatial. The paper will show how architectural hyper-models can be used on the construction site - both in the site office and on site using laptop computers and more compact hand-held devices - to decrease on site confusion and enable a faster and more complete understanding of the architect’s vision. The paper concludes with speculation on the types of additional information construction workers, architects and designers might want to access in the future and proposes additional technologies that could be provided

Evolution and Competition in the Market for Handheld Computers

Since the early 1990s, electronic organisers or electronic agendas have been evolving towards fully fledged, but miniature, computers. This paper is a case study about this market. Uniquely, and reminiscent of the home computer market in the 1980s, this is a market for personal computers not dominated by Microsoft. Or at least, not yet. In tracking the evolution of this market, the paper points especially to the importance of networking and standardization. The market for handheld computers is a small market, compared to the units shipped in the market for PCs. Nevertheless a surprisingly large number of vendors has been and still is active in this market. During the short history of this market, there have been several periods where technological breakthroughs created expectations of huge growth, with entry by new suppliers as a result. As the dust settled, the losers either changed strategy, or left the market altogether. The paper will argue that standardization and networking are major factors in explaining competitive success and the recent growth of the industry.industrial organization ;

Collaborative trails in e-learning environments

This deliverable focuses on collaboration within groups of learners, and hence collaborative trails. We begin by reviewing the theoretical background to collaborative learning and looking at the kinds of support that computers can give to groups of learners working collaboratively, and then look more deeply at some of the issues in designing environments to support collaborative learning trails and at tools and techniques, including collaborative filtering, that can be used for analysing collaborative trails. We then review the state-of-the-art in supporting collaborative learning in three different areas – experimental academic systems, systems using mobile technology (which are also generally academic), and commercially available systems. The final part of the deliverable presents three scenarios that show where technology that supports groups working collaboratively and producing collaborative trails may be heading in the near future

Augmented Tangible Surfaces to Support Cognitive Games for Ageing People

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-19695-4_27The continuous and rapidly increasing elderly population requires a revision of technology design in order to devise systems usable and meaningful for this social group. Most applications for ageing people are built to provide supporting services, taking into account the physical and cognitive abilities that decrease over time. However, this paper focuses on building technology to improve such capacities, or at least slow down their decline, through cognitive games. This is achieved by means of a digitally-augmented table-like surface that combines touch with tangible input for a more natural, intuitive, and appealing means of interaction. Its construction materials make it an affordable device likely to be used in retirement homes in the context of therapeutic activities, and its form factor enables a versatile, quick, and scalable configuration, as well as a socializing experience.This work received financial support from Spanish Ministry of Economy and Competitiveness under the National Strategic Program of Research and Project TIN2010-20488, and from Universitat Politécnica de Valencia under Project UPV-FE-2014-24.
