  1. Adding life and intelligence to Windows Mobile 6.5 Applications Andrej Radinger, MVP APPA Mundi Ltd. www.appamundi.com andrej@appamundi.com MOB303

  2. About Andrej Radinger • Director for Consulting and Training at APPAMundi • Microsoft MVP for Mobile Devicessince 2004 • Regularspeaker on Microsoft eventsintheregion • Contact me at: andrej@appamundi.com • Mobile Services: Consulting, Development, Training • http://www.appamundi.com

  3. Assumptions & Disclaimers • This is a level 300 session! • You already know the basics of Windows Mobile development with .NET Compact Framework • Making things easy: • Windows Mobile 6 Professional = Pocket PC • Windows Mobile 6 Standard = Smartphone • All demos in this session apply to bothWindows Mobile 6.1 & 6.5 • Based on hardware-specific APIs

  4. Agenda • Windows Mobile Device Input Options • Mobile UI Design Guidelines & Best Practices • Next Generation Input for Devices • Unified Sensor API (Codeplex) • Working with Accelerometers • Working with Light Sensors • Detecting Simple Touch Screen Gestures • Provide Sensory Feedback to Users • Summary

  5. Windows Mobile Device Form Factors • Pocket PC (including Pocket PC Phone) • Tactile screen, stylus, standard buttons • QWERTY Keyboard: Built-in, “slideable”, none • Smartphone • Numeric keypad or full QWERTY keyboard • No stylus, cursor keys • Industrial/Embedded • “Ruggedized” Pocket PCs • Numeric/Alphanumeric keypads • Handheld PC • Clamshell, Tablet-style • VGA, ½-VGA screen • QWERTY Keyboard

  6. Understanding the Windows MobileUser Interface • Limited Screen Real Estate • Limited Memory Environment • Touch-Sensitive Screen on Pocket PCs:Stylus or Finger Input • Soft Input Panel (Pocket PC) • Hardware Keys • Built-in/slideableKeyboards(on certain models) • Numeric Keypad (Smartphone) • Voice Commands

  7. Key User Interface Principles • Design a new UI for a mobile device,don’t port your desktop UI • Completely redesign the user interface • Business logic may be reusable • Choose the correct model based on the form factor • Pocket PC should always be full-screen • Limit free text entry on devices with no keyboards • Keep the user interface simple • Avoid control overcrowding • Limit the required number of clicks as much as possible • Take advantage of new UX hardware options!

  8. New UX Hardware Options • User Experience (UX) includes input & output • Touch Screen Gestures • Feedback via Vibration • Feedback via Sounds • Accelerometers • Light Sensors • Navigation Wheels • Capacitive Touch Screens* • Not featured on any Windows Mobile device announced to date

  9. Unified Sensor API • Allows developers to easily access the hardware sensors that are available on various devices • Accelerometer (GSensor) • Light Sensor • Stylus Sensor • Navigation Wheel • CodePlex Open Source Community Project • http://sensorapi.codeplex.com • Created by Koushik K. Dutta • http://www.koushikdutta.com • Devices: HTC Touch*, Samsung Omnia/Instinct

  10. Accelerometer: GSensor • Return a device orientation vector • The vector is the direction of force relative to the orientation of the device. • Tilt X: 0 is flat, -1000 to +1000 • Tilt Y: 0 is flat, -1000 to +1000 • Tilt Z: 0 is straight up, -1000 is flat, 1000 is face down • Switch between landscape/portrait mode • Can be used to as an alternative to4-way cursor keys +Y -X -Z +Z +X -Y

  11. Demo Unified Sensor API Working with the Accelerometer using GSensor

  12. Light Sensor • Return the ambient luminance based on a device’s light sensor • Single numerical value • Ranges from 0 to 30 • Change UI color scheme based onambient lighting • Create a new light sensor with HTCSensorOpen(HTCSensor.Light)in HTCSensorSDK.dll

  13. Demo Unified Sensor API Detecting Ambient Lighting with LightSensor

  14. Touch Screens & Gestures • Windows Mobile devices use a resistive touch screen: single touch point • Can detect simple gestures using the “mouse” events in .NET Compact Framework • Stylus and fingers fire mouse events in Compact Windows Forms • MouseDown: Capture the start position • MouseUp: Detect end position, calculate direction, even the distance if needed • Track the position with MouseMove if the user goes off-screen

  15. Demo Detecting Simple Screen Gestures Tracking the Stylus with “Mouse” Events in WinForms

  16. Providing Feedback to the User • Visual Cues on Screen • Playing Sounds • Vibrating the device

  17. Demo Vibration Providing vibration feedback to the user

  18. Playing Sound in NETCF 3.5 // Play custom sound files with SoundPlayer Dim soundplayer As New Media.SoundPlayer With soundplayer .SoundLocation = "\My Documents\My Ringtones\murloc.wav" .Play() End With // Play standard system sounds Media.SystemSounds.Asterisk.Play() Media.SystemSounds.Beep.Play() Media.SystemSounds.Exclamation.Play() Media.SystemSounds.Hand.Play() Media.SystemSounds.Question.Play()

  19. Summary • Users expect more from their mobile devices • Create a next generation user experience (UX) • Tap into the advanced hardware capabilities of your Windows Mobile devices • Make your device application input intuitive • Use simple gestures to add another layer of interaction to your mobile application • Provide audible and sensory feedbackto your users • Download and test drive the Windows MobileUnified Sensor API from CodePlex
