Context Sensitive Intelligence

Software-Development for Adaptation

Project Goals

In the CSI project we research towards an infrastructure for context-driven software adaptation. Our two foci are: support developers in building adaptive software, support end-users with intelligent self-adaptive software.

Organisation

CSI is funded by the Deutsche Telekom Laboratories.
The project started in autumn 2004 and runs until autumn 2007.

Motivation

In a world which is more and more provided with pervasive computing, end-users of mobile devices face an increasing complexity in using available, computer-assisted services in many different contexts. The users' mobile devices have to be adaptive to changing situations and requirements in a preferably automatic and user-friendly way. The developer needs a highly-flexible framework which enables users to make use of basic functionalities and provides service-providers with an easily extensible architecture to facilitate the development of new services.

Research Questions

• How should we model context?
• What kind of software adaptations are required?
• How should context changes be mapped to software adaptation needs?
• Which software technologies serve the demands for implementing adaptability most appropriately?

Hybrid positioning technologies are getting traction

Hybrid positioning technologies are getting traction

Many new LBS applications such as social networking, local search, pedestrian and mass transit navigation or geo-tagging are expected to be used in places such as indoor or urban canyons where GPS takes forever to have a fix - or never does. Therefore, alternative and hybrid positioning technologies such as Wi-Fi and Cell-ID will become increasingly important to offer a smooth experience to consumers.

“Users expect a seamless and transparent location experience regardless of application or environment,” says ABI Research director Dominique Bonte. “Since no single positioning technology can provide this, the future will be about hybrid positioning systems, combining A-GPS, Cell-ID, Wi-Fi, cellular, motion sensors, and even TV broadcast and proximity technologies such as Bluetooth, NFC and RFID. A-GPS, Wi-Fi and Cell-ID will be the winning combination offering accuracy, availability, interoperability and short fix times at low cost. It will represent 25% of all positioning solutions by 2014. Stand-alone Cell-ID and/or Wi-Fi will remain important in regions with low GPS handset penetration.“

Step by step this market is taking shape. Two announcements made last week are demonstrating it.
First, Skyhook Wireless, the leader in the Wi-Fi positioning space (the Boston-based company powers the iPhone), has upgraded its SDK to include Android support, as well as hybrid positioning (GPS+Cell-ID+Wi-Fi) which offers a comprehensive solution to software developers willing to add location to their mobile applications.

Second, the German software and service provider Spotigo announced that its WiFi-based Positioning Solution (“WiPS”) is now available in more than 25 countries. “The most important cities in countries like the United States, Germany, UK, Spain, France, Russia, India, Korea, etc. are covered significantly already”, said Spotigo in a statement. “We are looking forward to being able to provide a world-wide service within the next few months,” said Daniel Prümers, CEO of Spotigo.

Navizon’s community
In addition to these public announcements, New-York City-based Navizon has been harnessing the power of its community which nowadays counts over 800,000 members. Indeed, while Skyhook Wireless relies on a fleet of paid drivers that build a Wi-Fi map database, Navizon relies on its members who automatically report and update new Wi-Fi hotspots around the world. Moreover, some of these users are getting money in doing that, because Navizon choosed to reward its most active users. As a result, Navzon has built a decent Wi-Fi and cell-ID data map for cities in emerging or developing markets such as Moscow, St Petersburg, San Paolo, Istanbul, Bangalore or Johannesburg. It might take months - if not years - to Skyhook to get there. But the Boston-based company has the advantage to set its database mapping priority on its own and to have a tighter control over the data.

Google and Microsoft
Google has been building its own reference databases of cell-tower and/or Wi-Fi hotspot locations (called MyLocation) via user-generated content and/or self-learning mechanisms, and is offering it for free to developers. However, Google does not offer any service level agreement, does not disclose its coverage and has loose privacy rules. Microsoft is also starting to show interest in hybrid positioning technologies. Last week the Redmond- based corporation integrated cell tower triangulation into its Live Search Mobile application. It would not be surprising to see Microsoft interested in Wi-Fi positioning too.

If we look at the market as a whole, wireless operators are slowly but surely giving away their primacy over their customer’s location data, now offered as a web service by a wide variety of providers. The range of these providers is growing but there is however a strong barrier of entry: the gathering of Cell-ID and Wi-Fi data on a worldwide scale.

WIKITUDE - AR TRAVEL GUIDE
AUGMENTED REALITY ON THE ROAD

Wikitude is a mobile travel guide for the Android platform based on location-based Wikipedia content. It is a handy application for planning a trip or to find out about landmarks in your surroundings; 350,000 world-wide points of interest may be searched by GPS or by address and displayed in a list view, map view or cam view.
Simpel Search

Wikitude AR is a Top-50 finalist in Google's Android Developer Challenge . Wikitude has been launched along with the G1 phone in October 2008 and is now available in the Android Market.
Map View
SEARCH
POINTS OF INTEREST

Search 350,000 world-wide points of interests based on your current GPS location and address. To get started as easily as possible, two search options have been provided:

- Simple Search allows users to initiate a search just by pressing "Start Search"
- Advanced Search offers users additional search options (category, distance, and search term)
Wikitude for android - Sightseeing in Sevilla
MAP, LIST, ...
SEARCH RESULTS MAY BE VIEWED ON A MAP ...

Search results are displayed on a map (normal or satellite mode) as orange dots. There is a text bubble containing a short description next to the selected point of interest.
Map View
... AND CAMERA
SEARCH RESULTS MAY BE VIEWED ON THE PHONE'S CAMERA SCREEN

The truly compelling feature is the augmented reality cam view, users may hold the phone’s camera against a spectacular mountain range and see the names and heights displayed as overlay mapped with the mountains in the camera. Users may look out of an airplane window to see what is down there. Users may walk through a city like Seville, Spain, holding the phone’s camera against a building and Wikitude tells what it is.

About Jonna Häkkilä

I am team leader of User Experience Team at Smart Spaces Laboratory, Nokia Research Center, Finland. Prior to that role, I have been working in various units at Nokia since 2001, mainly with usability in product development. I received my PhD in 2007 at University of Oulu, Finland, and my thesis considered usability issues with context-aware mobile applications. I spent part of my post graduate study time at Griffith University, Australia, with prof. Liisa von Hellens (2003), and at Carnegie Mellon University, US, with prof. Anind Dey (2006). I have MSc in physics from University of Oulu (2000). My hobbies include snowboarding, skiing and science fiction.

Jonna Häkkilä research interests

My research interests are wide and versatile, and mostly to do with mobile computing and ubicomp - they include e.g. mobile multimedia, usability aspects of context-awareness, mobile user culture, and women and technology. Currently, my team is doing user experience research on emotional interaction, location-awareness, mobile wellness, and adaptive user interfaces. What I love in my job is to explore and try out new ideas, and to see how they are refined from original drafts to usable applications.
