Speckled Computing

D.K. Arvind (School of Informatics, University of Edinburgh)

Abstract: A specknet is a collection of autonomous specks which provides distributed services: each speck is capable of sensing and processing the data under program control; the specks themselves are connected as a mobile wireless network which processes information in a distributed manner.

Specknets link the digital world of computers to the physical world of sensory data. A network of wearable Orient specks, for example, is capable of tracking the orientation of the body parts, or the position of the person in the environment, and this information can be stored, manipulated and accessed remotely over the internet.

The tutorial will cover three aspects of Speckled Computing:
• Speck platforms, including the hardware and firmware
• Application of the on-body Orient wireless motion capture system in the healthcare, animation and sports sectors
• The science underpinning the interpretation of sensor data in these applications.
The attendees will have access to the Orient motion capture system and will get hands-on experience in interactive animation of virtual characters and in the real-time control of a bipedal robot performing tasks such as walking, standing on a leg and waving of arms.

Target Audience: The tutorial will benefit the following audiences:
• Decision makers in strategic technology developments in the healthcare, digital media and sports sectors
• Researchers in academia and industry with interests in wearable computing
• Application developers in wireless sensor networks, with particular interest in on-body sensor-based wireless motion capture systems
• Doctoral students who wish to gain hands-on experience of programming wearable wireless motion capture systems and exposure to algorithms for analysing and interpreting the data

• Scanning of the application spaces in healthcare, digital media and sports sectors for wearable wireless motion capture systems
• Detailed case studies of deployment in clinical gait analysis, 3-D animation, biomechanics of golf swings
• Unsupervised learning algorithms for the classification of motion data
• Hands-on experience in 3-D animation and in programming behaviour of a bipedal robot

The Future of Mobile Map Interaction - GIS meets wearable computing

A. Krueger (German Research Center for Artificial Intelligence (DFKI))

Abstract: Since 6000 years humans have used maps to navigate through space. Since then these maps have been supporting humans to perform a variety of other spatial tasks. Until a couple of decades ago most maps were drawn or printed on a piece of paper (or on material like stone or papyrus) of a certain size. This has changed dramatically. Nowadays most consumed maps are digital and presented on electronic devices. In this tutorial we will extrapolate from this situation and we will explore how the next generation of map devices and interaction styles will look like. This tutorial will explore new possibilities to navigate through maps using physical (whole body) gestures (e.g. multi-touch gestures) and discuss the challenges of map design and which arise from these interaction styles and the implications for the design of GIS software for mobile devices, large-scale multi-touch screens and wearable projectors.

Objective(s), significance and addressed audience: This tutorial aims at academics and industrial researchers, who want to learn about future map interaction concepts applicable to mobile and wearable devices as well as to large scale multi-touch surfaces. The tutorial does not require deep technical and formal knowledge and does not expect that the audience is familiar with Geoinformation Systems. All methods are explained by examples. The tutorial is therefore suitable for students, who want more in depth information on the topic of map interaction, senior researchers, who are interested in an overview and industrial researchers who want to learn about possible future applications.

• What is a GIS - a brief introduction
• Interaction styles for future mobile maps
• Mobile Map interaction technologies
• Evaluation methods for mobile map interaction

Brief Bio of the Presenter:
Antonio Krüger received a diploma in computer science and economics at Saarland University in 1995. Afterwards he joined the Cognitive Science Graduate Programme of the same University and finished it with a doctoral degree in 1999. His doctoral thesis was on the "Automated Abstraction of 3D-Graphics".He was early involved in several Artificial Intelligence projects at the German Research Centre for AI (DFKI GmbH), and later from 1999-2003 at the Intelligent Systems Lab of Saarland University as a Senior Researcher. In 2000 he co-founded the Universityspin-off Eyeled GmbH, a company focusing on mobile computing solutions. Within the company he is responsible for the technology transfer of university research. From 2004 to 2009 he was an associate professor for Geoinformatics and Computer Science at Münster University, Germany. From 2005 to 2009 he was elected managing director of the institute for Geoinformatics at the same University. Since 2009 Antonio Krüger has an appointment as a full professor for Computer Science at Saarland University. At the same time he is the Scientific Director of the "Innovative Retail Laboratory (IRL)" at the German Research Center for Artificial Intelligence (DFKI) in Saarbrücken, Germany.

Antonio's main research areas are Intelligent User Interfaces and mobile and ubiquitous context-aware Systems. He worked on the automatic generation of graphics for technical documentations, intelligent navigation systems and personalized media generation. In this context he looked at generation processes that take into account both the limited technical resources of output devices and the limited cognitive resources of the users. More recent examples of his research come from the domain of mobile and ubiquitous computing. Here, Antonio is involved in projects on interactive display networks, mobile augmented reality and interactive surface computing.

Antonio is co-organising the annual Smart-Graphics Symposium and served on various program committees in the field of intelligent mobile systems, e.g. Intelligent User Interfaces, User Modeling, Ubicomp, Mobisys, and Pervasive Computing.

Building activity recognition applications for the iPhone platform

K. Kunze, D. Bannach (ESL, University of Passau)

Abstract: In this tutorial we will discuss how to leverage the iPhone platform for experimental setups and applications in the field of context and activity recognition.
Starting with a short intro about the capabilities of the iPhone in terms of on-board sensors, computing power and accessibility, we discuss how to deal with context-aware application development for mobile devices. The participants can try to build a recognition system themselves recording sensor data, training classifiers, testing them offline and online.

Objectives: The participants will learn how to prototype context aware applications with focus on the features and limitations of the iphone platform.
To participate, a Macbook (intel based) and an iphone are useful, however they are not needed. The offline plotting, recognition and training scripts are in python (enthought suite), therefore some knowledge of python is helpful, yet also not required.
The Enthought suite can be easily installed on Windows, Mac and Linux.
Both presenters have several applications available on the appstore since over a year.

• Introduction
• Overview of the iPhone for activity recognition
• Primer into prototyping tools
• Recording and analyzing data from iPhone sensors
• Building activity recognition classifiers
• Testing offline/online
• Summary
