ABSTRACT This paper aims to present a model for an interactive and hybrid digital TV focused on global services and applications framework. The model proposed aims to improve the hybrid broadcast-broadband model with features which run worldwide using a PaaS cloud service, browser applications in a global compliance and second screen scenarios involving pervasive computing. The proposed architecture and a development baseline analysis indicate the feasibility to develop a global interactive TV scenario.

Substantial stumbling blocks confront computer-illiterate elders. We introduce a novel user interface technology to lower these start up costs: the book as user interface, or BUI. Book pages contain both step-by-step instructions and tangible controls, turning a complex interaction into a walk-up-and-use scenario. The system expands support past the technical artifact to a go-to relationship. ElderMail users designate an internet-savvy trusted friend or relative to help with complex tasks. In this paper, we conduct a preliminary evaluation of a BUI-based email system, and report our findings. While research has augmented paper artifacts to provide alternate access into the digital world, we find that elders use the BUI as a way to circumvent the digital world.

Diabetes occurs due to destruction of Beta-cells in the
pancreatic islets of Langerhans with resulting loss of insulin
production. The result of insufficient action of insulin is an
increase in blood glucose concentration. The diagnosis of Diabetes
must always be established by a blood glucose measurement made
in an accredited laboratory. The alternative way to measure a
deficiency of insulin from the Beta-cells of pancreatic islets uses
iris diagnosis. Evaluating the iris is done by detecting the presence
of some broken tissue in iris. However, conventional iris diagnosis
is always concerned with the identification of syndromes rather
than with the connection between abnormal iris tissue
appearances and diseases. In this paper, we present a novel
computerized iris inspection method aiming to address these
problems for detecting insulin deficiency from the Beta-cells of
pancreatic islets. First, quantitative features, textural measures
are extracted from iris images by using popular digital image
processing techniques. Then, Neighborhood based Modified
Backpropagation using Adaptive Learning Parameters (ANMBP)
method is employed to model the relationship between
quantitative features and pancreatic abnormalities as caused of
insulin deficiency. The effectiveness of this method is tested on 12
patients with Diabetes, and the diagnostic results predicted by the
previously trained ANMBP classifiers are compared with the
calculation of HOMA-B, obtained 83.3% accuracy in detecting
pancreas disorders.

We present a general model and information server for the digital annotation of printed documents. The resulting annotation framework supports both informal and structured annotations as well as context-dependent services. A demonstrator application for mammography that features both enhanced writing and reading activities is described.

The Internet of Things (IoT), in general, is a compelling paradigm that aims to connect everyday objects to the Internet. Nowadays, IoT is considered as one of the main technologies which contribute towards reshaping our daily lives in the next decade. IoT unlocks many exciting new opportunities in a variety of applications in research and industry domains. However, many have complained about the absence of the real-world IoT data. Unsurprisingly, a common question that arises regularly nowadays is "Does the IoT already exist?". So far, little has been known about the real-world situation on IoT, its attributes, the presentation of data and user interests. To answer this question, in this work, we conduct an in-depth analytical investigation on real IoT data. More specifically, we identify IoT data sources over the Web and develop a crawler engine to collect large-scale real-world IoT data for the first time. We make the results of our work available to the public in order...

Effective deployment of ubiquitous technologies can help companies improve the business efficiency, especially for those ICT (Information communication technology) companies who are involved in M-business, M-commerce, and etc. However, there are many factors could affect the performance of the ubiquitous technologies deployment, such as the company’s management, the employee’s coordination, and etc. In this paper, we are focused on the environmental factors that would have an impact on the performance of organizations which have deployed or is deploying ubiquitous technologies, and investigate more than 50 Chinese ICT companies. According to our findings, in the context of China, a sensible, dependent, and interactive business relationship with the outside environment will have a positive impact on their ubiquitous technologies deployment’s performance, while the decentralization and hierarchism within organizational structure in the inside environment will have a negative impact on their ubiquitous technologies deployment’s performance.

Abstract. Free/Libre and Open Source Software (FLOSS) is a process of software development, a method of licensing and a philosophy. Although FLOSS plays a significant role in several market areas, the impact in the health care arena is still limited. FLOSS is promoted as one of the most effective means for overcoming fragmentation in the health care sector and providing a basis for more efficient, timely and cost effective health care provision. The 2008 European Federation for Medical Informatics (EFMI) Special Topic Conference (STC) explored a range of current and future issues related to FLOSS in healthcare (FLOSS-HC). In particular, there was a focus on health records, ubiquitous computing, knowledge sharing, and current and future applications. Discussions resulted in a list of main barriers and challenges for use of FLOSS-HC. Based on the outputs of this event, the 2004 Open Steps events and subsequent workshops at OSEHC2009 and Med-e-Tel 2009, a four-step strategy has been pr...

Markers denoting the location of landmarks and search results in mobile apps are used extensively in many applications. The presence of large volumes of markers clutters the information space, making it hard for users to visually differentiate between highly important or recommended locations, or to browse the depicted locations in order to identify suitable choices. In this paper, we present the results of a participatory design process to improve the utility of marker icons in a tourist application. We explore three alternative designs derived from this process by implementing and testing a mobile application that recommends venues based on their popularity (check-in count) in a well-known social network (FourSquare). Our lab experiments highlight aesthetic, utility and performance issues in marker design that affect the usability of mobile map applications.

We present the design, implementation, deployment and evaluation of a novel urban computing infrastructure called UBI-hotspot. It is effectively a large interactive public display embedded with other computing resources. We have deployed a network of UBI-hotspots around downtown Oulu, Finland, to establish a public laboratory for conducting experimental ubiquitous computing research in authentic urban setting with diverse real users and with sufficient scale and time span. We focus on the first version of the UBI-hotspot which offers a wide range of services via different interaction modalities. We analyze the usage and user acceptance of the UBI-hotspots from qualitative and quantitative data collected over a period of eight months. Our first observations show that this type of infrastructure may be a useful addition to the urban space.

RFID technology is one of the forerunners of pervasive computing, and as such is expected to play an important role in many applications of daily life in the near future, especially in the form of Smart Labels. Based on market investigations and a material analysis of a Smart Label we showed that the use of Smart Labels does not considerably affect the recycling or disposal of packaging materials, if precautionary measures are taken, such as eco-design and, where necessary, process modifications.

Software Design and Media Design - tools to designMobile and Sensory Interfaces and Interactive EnvironmentsGeert de HaanCommunication, Media and Information TechnologySection Media Technology / Human Centered ICTRotterdam University of Applied SciencesP.O.Box 25035, 3001 HA, RotterdamThe Netherlandsg.de.haan@hr.nlABSTRACTThis  paper  discusses  ETAG,  a  formal  model  for  design representation, and ETAG-based design, a method for user interface  design,  and  the  two  principal  facilities  they provide  to  accommodate  different  types  of  users  in  the design  of  user  interfaces.  The  paper  starts  with  an introduction  of  ETAG  as  a  design  representation.  This  is followed by a description of ETAG-based design and using the  notation  to  represent  relevant  aspects  of  the  work context.    Next,    we    discuss    the    differences    between computer  software  design  and  media  product  design, concluding  that  media  design  is  a  much  more  flexible, iterative  process  and  prototyping-based  process  in  which adaptation  of  the  design  of  mobile  applications  extends into    the    maintenance    phase.    To    cover    further developments towards  focussing  on user needs and wishes by  means  of  co-design  practices,  and  to  cover  for ubiquitous  computing  and  interaction  with  sensors  and interactive  environments,  we  propose  to  use  sensory  labs and  to  create  living  labs  to move  the  usability  lab into the real world
