Context In UX Context In UX Presentation Transcript

  • Use of Context Information for User Experience Design
    Mikhail Matveev,National Technology Officer,Microsoft Russia
    Daniel Kornev,Program Manager,Microsoft Russia
    Alexander Popov,MSTLab,Moscow State University
  • Agenda
    Existing examples of context information
    Context definition
    Sensors and their applications
    Applying context information
    Sensor and Location Platform
    Market opportunities
  • // Existing examples of context information
  • Apple iPhone
    Natural User Interface:
    Zoom in/out
    Physical inertia applied to digital objects
    Context-Aware Interfaces:
    UI Orientation (changes when physical orientation changes)
    Light-aware UI
    Screen uses presence sensor to automatically turn off while on call
    Automatic switching between tasks with applying priorities (media player pauses while on call and after call resumes playing)
  • Contextual tabs in Office 2007
    Natural User Experience:
    Ribbons for editing special objects like images, charts, tables etc appear only when these objects are selected by user
  • GPS and location-based applications
    Context-Aware User Experiences:
    Detection of user’s location
    Contextual information – POIs near user
    Traffic and auto-correction of trip
    Show user’s friends location on map in real mode
  • Sound profiles in HTC Touch Pro
    Sound Profiles:
    Alarm can wake you even if you turned off system sound off
    Sound profiles – normal/vibration/without sound
    Special profile “Automatic” – switches app behavior to “Vibration” while on meetings (data is populated from Calendar)
  • Existing examples
    Ambient Light Sensors in cars,
    GPS and location-aware applications,
    IM Presence (Skype/Messenger/ICQ)
    Changing screen layout depending on device’s physical orientation (iPhone)
    Contextual Tabs inMicrosoft Office 2007
    Sound Profiles in HTC Touch Pro

  • // Context definition
  • Context is…
    Situation, in which the product is used and situation changes
    Let’s take a look on definitions of Context given by different companies and organizations, Intel and ISO
  • What is Context? (Intel)
    © Intel 2008, “Context Aware User Interface”, Intel Developer Forum
    Context-aware system can be aware of:
    Environmental Contexts
    Physical environment
    User context
    Physical state
    Physiological state
    Platform Context
    Batter Status
    Platform Features
    Running Apps
    Memory usage
  • What is Context? (ISO)
    Context combines users, their goals and tasks, infrastructure (hardware, software, materials), physical and social environment in which the product is used.*
    *as defined by ISO 9421-11
  • What are context-aware systems?
    Context-aware systems are those changing their behavior when the situation changes
  • // Sensors and their applications
  • Sensors
    Sensoris a device that measures a physical quantity and converts it into a signal which can be read by an observer
    Sensors make possible for computer devices to detect elements of contexts that are hard to impossible to discover by using traditional methods.
  • Sensors and context-aware solutionsare on the market already
    Research Institutes
    Software Developers
  • // Applying context information
  • Ideas to think about
    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.
    The display adjusts brightness and contrast based on current lighting conditions.
    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.
    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.
    When the display is rotated, layout changes from landscape to portrait and vice versa.
    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.
  • // Sensor and Location Platform
  • Limitations of sensors today
    Location devices are exposed as virtual COM ports
    Exclusive application access
    Not secure
    Proprietary data formats (NMEA, others)
    GPS doesn’t work indoors
    Hard to support multiple technologies at once
    Sensors are integrated as vertical solutions
    Applications need to know sensorhardware specifics
    Limited adoption and scope
  • Sensor and Location Platform
    New platform for Windows 7
    Provides unified driver model for all types of sensor devices
    Physical sensors (e.g., GPS devices, Light Sensors)
    Logical sensor (e.g., Wi-Fi triangulation resolver)
    Provides standard APIs for accessing sensors
    Sensor API: C++/COM
    Raw access to any sensor
    Location API: C++/COM, IDispatch (scriptable)
    Abstracted API for location data
    Puts user in control of information disclosure
  • Sensor and Location Platform
    Gadget or Script
    Location API
    Location IDispatch Interface
    Sensor API
    Location and Other Sensors Control Panel
    Sensor Class Extension
    Sensor Class Extension
    UMDF Sensor Driver
    UMDF Sensor Driver
    Logical Location Sensor
  • Location Platform benefits
    Single API call to answer “Where am I?”
    Independent of provider used todetermine location
    Synchronous and Asynchronous models
    Script/automation compatible
    Automatic transition between providers
    Most accurate providers have priority
    Concurrent access for multiple applications
    Default Location
    Provided by user as fallback when no other sources are available
  • Types of location data
    Geographic Data (ILatLongReport)
    Latitude, longitude, altitude, associated error required
    Most common format
    Best format for precise location
    Can reverse geo-code later
    Civic Address (ICivicAddressReport)
    Zip, Country required
    Most human readable
    Best for ‘rough’ location estimates,street directions
  • Demo
  • Privacy and Access Control
    Location data is considered PII
    User consent is required to share data
    All sensors are disabled by default
    Admin rights requiredto enable a sensor
    Sensors can be configured on a per-user basis
    “Enable Dialog”invoked by applications
