    1. 1. Use of Context Information for User Experience Design<br />Mikhail Matveev,National Technology Officer,Microsoft Russia<br />Daniel Kornev,Program Manager,Microsoft Russia<br />Alexander Popov,MSTLab,Moscow State University<br />
    2. 2. Agenda<br />Existing examples of context information<br />Context definition<br />Sensors and their applications<br />Applying context information<br />Sensor and Location Platform<br />Market opportunities<br />Summary<br />
    3. 3. // Existing examples of context information<br />
    4. 4. Apple iPhone<br />Natural User Interface:<br />Gestures<br />Zoom in/out<br />Physical inertia applied to digital objects<br />Context-Aware Interfaces:<br />UI Orientation (changes when physical orientation changes)<br />Light-aware UI <br />Screen uses presence sensor to automatically turn off while on call<br />Automatic switching between tasks with applying priorities (media player pauses while on call and after call resumes playing)<br />
    5. 5. Contextual tabs in Office 2007<br />Natural User Experience:<br />Ribbons for editing special objects like images, charts, tables etc appear only when these objects are selected by user<br />
    6. 6. GPS and location-based applications<br />Context-Aware User Experiences:<br />Detection of user’s location<br />Contextual information – POIs near user<br />Directions<br />Traffic and auto-correction of trip<br />Show user’s friends location on map in real mode<br />
    7. 7. Sound profiles in HTC Touch Pro<br />Sound Profiles:<br />Alarm can wake you even if you turned off system sound off<br />Sound profiles – normal/vibration/without sound<br />Special profile “Automatic” – switches app behavior to “Vibration” while on meetings (data is populated from Calendar)<br />
    8. 8. Existing examples<br />Ambient Light Sensors in cars,<br />GPS and location-aware applications,<br />IM Presence (Skype/Messenger/ICQ)<br />Changing screen layout depending on device’s physical orientation (iPhone)<br />Contextual Tabs inMicrosoft Office 2007<br />Sound Profiles in HTC Touch Pro<br />…<br />
    9. 9. // Context definition<br />
    10. 10. Context is…<br />Situation, in which the product is used and situation changes<br />Let’s take a look on definitions of Context given by different companies and organizations, Intel and ISO<br />
    11. 11. What is Context? (Intel)<br />© Intel 2008, “Context Aware User Interface”, Intel Developer Forum<br />Context-aware system can be aware of:<br />Environmental Contexts<br />Physical environment<br />Devices<br />Services<br />User context<br />Identity<br />Physical state<br />Physiological state<br />Activities<br />Contacts<br />Preferences<br />Platform Context<br />Location<br />Motion<br />Network<br />Batter Status<br />Platform Features<br />Running Apps<br />Memory usage<br />
    12. 12. What is Context? (ISO)<br />Context combines users, their goals and tasks, infrastructure (hardware, software, materials), physical and social environment in which the product is used.*<br />*as defined by ISO 9421-11<br />
    13. 13. What are context-aware systems?<br />Context-aware systems are those changing their behavior when the situation changes<br />
    14. 14. // Sensors and their applications<br />
    15. 15. Sensors<br />Sensoris a device that measures a physical quantity and converts it into a signal which can be read by an observer<br />Sensors make possible for computer devices to detect elements of contexts that are hard to impossible to discover by using traditional methods.<br />
    16. 16. Sensors and context-aware solutionsare on the market already<br />+<br />Universities<br />Research Institutes<br />+<br />Partners<br />Software Developers<br />
    17. 17. // Applying context information<br />
    18. 18. Ideas to think about<br />The computer volume automatically adjusts based on the noise level of the environment. For example, when I’m in a noisy location, my media player sets the volume level up.<br />The display adjusts brightness and contrast based on current lighting conditions.<br />Text, links, and buttons get bigger on my touch-enabled mobile computer when I’m on-the-go, so they are easier to use. For example, when I’m holding my device in hands, the text and images on the screen automatically get larger.<br />The computer knows when it has moved from work to home and changes the desktop background. It can also hide work-related environment and show game and entertainment applications shortcuts.<br />When the display is rotated, layout changes from landscape to portrait and vice versa.<br />The computer can monitor the health status of me or a person I care about. For example, it can monitor their vital signs, including blood pressure, heart rate, and blood sugar levels.<br />
    19. 19. // Sensor and Location Platform<br />
    20. 20. Limitations of sensors today<br />Location devices are exposed as virtual COM ports<br />Exclusive application access<br />Not secure<br />Proprietary data formats (NMEA, others)<br />GPS doesn’t work indoors<br />Hard to support multiple technologies at once<br />Sensors are integrated as vertical solutions<br />Applications need to know sensorhardware specifics<br />Limited adoption and scope<br />
    21. 21. Sensor and Location Platform<br />New platform for Windows 7<br />Provides unified driver model for all types of sensor devices<br />Physical sensors (e.g., GPS devices, Light Sensors)<br />Logical sensor (e.g., Wi-Fi triangulation resolver)<br />Provides standard APIs for accessing sensors<br />Sensor API: C++/COM<br />Raw access to any sensor<br />Location API: C++/COM, IDispatch (scriptable)<br />Abstracted API for location data<br />Puts user in control of information disclosure<br />
    22. 22. Sensor and Location Platform<br />Gadget or Script<br />Application<br />Application<br />Location API<br />Location IDispatch Interface<br />Sensor API<br />User<br />Location and Other Sensors Control Panel<br />System<br />Sensor Class Extension<br />Sensor Class Extension<br />UMDF Sensor Driver<br />UMDF Sensor Driver<br />Sensor<br />Device<br />Logical Location Sensor<br />(Triangulation)<br />
    23. 23. Location Platform benefits<br />Single API call to answer “Where am I?”<br />Independent of provider used todetermine location<br />Synchronous and Asynchronous models<br />Script/automation compatible<br />Automatic transition between providers<br />Most accurate providers have priority<br />Concurrent access for multiple applications<br />Default Location<br />Provided by user as fallback when no other sources are available<br />
    24. 24. Types of location data<br />Geographic Data (ILatLongReport)<br />Latitude, longitude, altitude, associated error required<br />Most common format<br />Best format for precise location<br />Can reverse geo-code later<br />Civic Address (ICivicAddressReport)<br />Zip, Country required<br />Most human readable<br />Best for ‘rough’ location estimates,street directions<br />
    25. 25. Demo<br />
    26. 26. Privacy and Access Control<br />Location data is considered PII<br />User consent is required to share data<br />All sensors are disabled by default<br />Admin rights requiredto enable a sensor<br />Sensors can be configured on a per-user basis<br />“Enable Dialog”invoked by applications<br />
