  • Presentation Title | Month 2012 | 6 Smart Watches – Battery Life • How often do we need to charge them • Varies from a couple days (Sony) to a week (Pebble) to a few months/year (G-Shock) • Type of charger
  • Presentation Title | Month 2012 | 7 Smart Watches – Connectivity • Do they need to connect directly to Smart Phones or does it work as a stand-alone? • Reliability of connection • Inter-operability with Bluetooth – which may vary depending on Android version/vendor • Stability over time – requires a reboot • iOS or Android? • Sony is Android only • Support may vary between iOS and Android • Wifi 3/4G Bluetooth
  • Presentation Title | Month 2012 | 8 Smart Watches – Software Capability • Typically the hardware is more advanced than the software • Software needs to catch up • Vendor’s focus may be hardware • Software quality • Many subtle issues (especially on Android) • Getting send/subject/preview of email • Accessibility bug in Samsung • Grabbing notification info from 3rd party app
  • Presentation Title | Month 2012 | 9 Smart Watches – At a Glance & Hands-Free • Always on watch • Dynamic info • Highly Personal & • Contextually Aware • Vibration and notification alerts
  • Presentation Title | Month 2012 | 10 One Watch-face – Changes over 24 hours

  • Presentation Title | Month 2012 | 12 MotoACTV Pebble MetaWatch Sony SmartWatch 2 (SW2) Sony SmartWatch 1 (MN1) Environmental ***** *** *** ***** ** Battery * **** *** *** ** Connectivity ** *** ** **** *** Software Capability * ***** ** **** ***** “At a glance” & Hands-Free ** **** **** *** *** Overall ** **** *** **** ***
  • Presentation Title | Month 2012 | 13 Smart Watches – Killer Use Cases? • Real-time Notifications • “Hands-Free” and “At a Glance” • Real-time Control – phone calls, music, home automation, Powerpoint/Chromecast on remote PC • Use case - two watches connect to the same Android • Accessibility
  • Presentation Title | Month 2012 | 14 Smart Watches – Killer Use Cases? • Swappable watch bands • NMA vs IMO
  • Presentation Title | Month 2012 | 18 • Challenges • Opportunities • Pebble Development • Sony Development • Augmented SmartWatch Pro Architecture • Canvas & Augmented – Plug-in Architecture for Pebble
  • Presentation Title | Month 2012 | 19 Android Specific Challenges • Something simple like getting sender/subject from an email is not so simple: • Multiple apps for email (Gmail, K9, Exchange, Touchdown, Enhanced Mail, …) • Multiple Versions of the Email App • Multiple Versions of Android • Multiple methods of getting Notification info in Android • 1st Email vs 2nd unread email
  • Presentation Title | Month 2012 | 20 Android Opportunity • Multiple Methods of Extracting Notification info • Varies by app/version/Android • At least 4 methods (including reading app DB via root) • Ability to “Optimize for specific Apps” • Filter out duplicates (Spotify) • Filter out frequent updates (Google Navigation) • Filter out “noise” ongoing call notifications (Skype, Viber) • Ability to reformat info to condense into Smart Watch Limited Space: • Remove Special Characters/Spaces • Reformat with pertinent info at the start (Google Now)
  • Presentation Title | Month 2012 | 21 Android - Pebble Specific • 3rd Software Ecosystem –Pebble biggest’s advantage • Three Software Models: • Android App – communicate via Intents to Pebble software • Can send notifications to Pebble or override the music app info • 2-way info possible only via Music App (buttons via BT) • Pebble Watchface App – Runs on Pebble watch using Pebble SDK • Best for 2-way control, flexibility • Need to develop in C • Hybrid – Combination of the two
  • Presentation Title | Month 2012 | 22 Android - Pebble Specific • Canvas Watch-Face – 3rd Party Plug-in approach • 1-way only (send info to Pebble) • Innovative approach • Suggestion to 3rd Party Developers • Plug-in approach as Canvas but as a Pebble App to allow 2-way communication
  • Presentation Title | Month 2012 | 23 Android – Sony Specific • Android App only via Sony SDK • Render a bitmap/layouts -> sent to Sony Watch for display • Touch/button input (swipe, double tap, position-sensitive) • No programmatic access to side button • Concept of widget vs App mode – no vibration in widget • Colour advantage • Issues • Touch is not as reliable as buttons • SmartWatch 1 display is not viewable in sunlight • Initially “at a glance and hands free” difficult to implement
  • Presentation Title | Month 2012 | 24 Android – Sony Specific • Initially – auto display of any bitmap challenging to do • Show Icon was the most common approach – not hands- free • It is possible to do this: Intent i = new Intent(Control.Intents.CONTROL_START_REQUEST_INTENT); i.putExtra(Control.Intents.EXTRA_AEA_PACKAGE_NAME,whichApp); if (Utils.isSonyWirelessHeadsetRunning(this)) i.setPackage("com.sonyericsson.extras.smartwirelessheadsetpro"); else i.setPackage("com.sonyericsson.extras.smartwatch"); sendBroadcast(i, Registration.HOSTAPP_PERMISSION);
  • Presentation Title | Month 2012 | 25 Android – Sony SmartWatch 2 • New SDK is compatible with the older watch (simultaneous notifications and widget mode not there yet) • 220x176 display resolution • Will scale up the older 128x128 apps (default) • Highly recommended to optimize for newer display size • Additional “buttons” accessible to app options/back • Native support for additional building blocks (lists etc) to rapidly build richer apps • Lack of 3rd party APIs for Watchfaces (hence cannot be a Pebble killer yet) • low power mode may offer a potential solution
  • Presentation Title | Month 2012 | 26 Architecture of Augmented SmartWatch Pro • Key Objectives • Support Open APIs (both into Augmented and into other apps) • Concurrent Support for Multiple SmartWatches • Integration with Tasker (Key 3rd party automation app)
  • Presentation Title | Month 2012 | 27 Android Broadcasts (SMS, Incoming Calls, Dock, Power Connected, K9, Alarms, Network, Pebble Connect) 3rd Party Apps/Tasker Intent API com.alk.k9. add.action
  • Presentation Title | Month 2012 | 29 Pebble Canvas Plug-In Integration • Future of the WatchFace • Dynamic, Contextual, High Personal • Simple APIs: • Registration of Plug-ins • Refresh of Data • On-Demand Data (text or image) • Interface Class (reuse as-is from Canvas Author, just copy into your project) • Provide implementation of above APIs (plus any extensions) • Highly recommended
  • Presentation Title | Month 2012 | 30 Augmented Plug-In Extensions for Canvas • Dynamic WatchFace based on notification content • Dynamic Image based on sender/Notification • Dynamic content (notification alert vs post-alert) • Tasker/3rd party Intent API • Multiple Asynchronous Plug-ins for Text info • Dynamic horizontal bars – to convey state info • Fitbit, Klout + Withings Info
  • Presentation Title | Month 2012 | 31 Lessons Learned
  • Presentation Title | Month 2012 | 32 Lessons Learned - Augmented SmartWatch Pro • Origins of the App • Key App Stats • Pricing • App Sales
  • Presentation Title | Month 2012 | 33 Origins - Augmented SmartWatch Pro • Initial use case • Sony break-thru • Reduce Tech Support issues - > Paid app
  • Presentation Title | Month 2012 | 34 Android App Stats -
  • Presentation Title | Month 2012 | 35 Key App Stats • Downloads – 7000+ • Installs to Downloads Ratio – 60% • Ratings – 4.1 • No ability to determine breakdown by Smart Watch – No Analytics (on purpose)
  • Presentation Title | Month 2012 | 36 Pricing an Application? I think pricing in the Android ecosystem is weird. If you would have charged $15 for it I wouldn’t have bought it. Not because it’s a lot of money but because hardly anyone does that besides the productivity suites. … Send me your PayPal and I’ll send you $10. I checked and the above address isn’t registered.
  • Presentation Title | Month 2012 | 37 Pricing an Application? THIS APP IS WAY WAY WAY TO OVER PRICED AND YOU INTEND TO INCREASE IT. GET IT WORKING AT 100% PERCENT B 4 OVER PRICING GREEDY ONE.REPLYS WILL NOT B SEEN BECAUSE THEY WILL JUST BE HYPOCRITE RESPONSES TO BEING SCHOOLED.
  • Presentation Title | Month 2012 | 38 Raising the price by 60% Accelerated Downloads!
  • Presentation Title | Month 2012 | 39 App Sales Tip - Appmonger app to track sales Price Changes impact Refunds – 17% refunds (@1 out of every 7) Refunds after 15 minute window Purchasing outside of Play store Holiday sales spike? • don’t decrease the price increase it 
  • Presentation Title | Month 2012 | 40 App Sales – By Day of Week & Country
  • Presentation Title | Month 2012 | 41 Smart Watches – Conclusions • There is no dominant player today • Highly personal – use cases depend on the individual • Software is terribly lacking – hardware is advanced • Great opportunity for developers (call to action) @augmentedtraff
