Open Source Virtual Worlds and Low Cost Sensors for Physical Rehab of Patients with Chronic Diseases
For patients with chronic diseases, exercise is a key part of rehab to
deal better with their illness. Some of them do rehabilitation at home with telemedicine
systems. However, keeping to their exercising program is challenging
and many abandon the rehabilitation. We postulate that information technologies
for socializing and serious games can encourage patients to keep doing
physical exercise and rehab. In this paper we present Virtual Valley, a low cost
telemedicine system for home exercising, based on open source virtual worlds
and utilizing popular low cost motion controllers (e.g. Wii Remote) and medical
sensors. Virtual Valley allows patient to socialize, learn, and play group based
serious games while exercising
Managing uncertainty in sound based control for an autonomous helicopter
In this paper we present our ongoing research using a multi-purpose, small and low cost autonomous helicopter platform (Flyper ). We are building on previously achieved stable control using evolutionary tuning. We propose a sound based supervised method to localise the indoor helicopter and extract meaningful information to enable the helicopter to further stabilise its flight and correct its flightpath. Due to the high amount of uncertainty in the data, we propose the use of fuzzy logic in the signal processing of the sound signature. We discuss the benefits and difficulties using type-1 and type-2 fuzzy logic in this real-time systems and give an overview of our proposed system
On the Economics of Innovation Projects Product Experimentation in the Music Industry
The paper is conceptual, combining project and economic organization literatures in order to explain the organization and management of market-based projects. It dedicates particular focus to projects set up in order to facilitate product innovation through experimentation. It investigates the internal vs. market economies of scale and scope related to projects, as well as the issues of governance, planning and coordination related to reaping such economies. Incorporating transaction cost perspectives as well as considerations of labour markets, the paper explains the management of market-organized innovation projects by virtue of localized project ecologies and local labour markets of leaders and boundary spanners. It illustrates its arguments with a case study of the Recorded Music industry.Project management, product innovation
A microtonal wind controller building on Yamahaâs technology to facilitate the performance of music based on the â19-EDOâ scale
We describe a project in which several collaborators adapted an existing instrument to make
it capable of playing expressively in music based on the microtonal scale characterised by equal
divsion of the octave into 19 tones (â19-EDOâ). Our objective was not just to build this instrument,
however, but also to produce a well-formed piece of music which would exploit it
idiomatically, in a performance which would provide listeners with a pleasurable and satisfying
musical experience. Hence, consideration of the extent and limits of the playing-techniques of
the resulting instrument (a âWind-Controllerâ) and of appropriate approaches to the composition
of music for it were an integral part of the project from the start. Moreover, the intention
was also that the piece, though grounded in the musical characteristics of the 19-EDO scale,
would nevertheless have a recognisable relationship with what Dimitri Tymoczko (2010) has
called the âExtended Common Practiceâ of the last millennium. So the article goes on to consider
these matters, and to present a score of the resulting new piece, annotated with comments
documenting some of the performance issues which it raises. Thus, bringing the project to
fruition involved elements of composition, performance, engineering and computing, and the
article describes how such an inter-disciplinary, multi-disciplinary and cross-disciplinary collaboration
was co-ordinated in a unified manner to achieve the envisaged outcome. Finally, we
consider why the building of microtonal instruments is such a problematic issue in a contemporary
(âhigh-techâ) society like ours

Active diffusers : some prototypes and 2D measurements
Diffusing devices are used to improve room acoustics in a wide variety of applications. The dispersion generated by current diffuser technologies is often limited to mid-to-high frequencies because low-frequency diffusers are usually too large to be easily accommodated. To extend the bandwidth of diffusers to a lower frequency a new approach is proposed, that is to use active control technology. In particular, active impedance techniques have been exploited to create non-absorbing diffusers, and hybrid structures that partly absorb while dispersing any reflected sound. This paper presents results mostly from a feedforward structure. It is found that achieving active dispersion without absorption other a worthwhile bandwidth can be more difficult than achieving active absorption due to the more complex target impedance that the controller needs to learn. Measurements on polar responses provide evidence that the active diffusers can achieve wider bandwidth dispersion. Boundary element modelling has enabled the design of these structures to be examined in more application-realistic set-ups
