The Future!

“Wearables and connectables will herald a fast-changing local network of customer context. Devices worn on or near the body that sense and relay information will be embedded in clothing, accessories, and even the body itself.17 First-generation wearables like the Nike+ FuelBand and Fitbit will give way to internal biomedical instruments, shoes that generate power to recharge devices, and golf clubs that provide swing telemetry. Connectable home alarm systems, automobiles, and scales will function in a similar way. Developers will tap into these new information sources, with a phone or tablet acting as a local combination of router and remote-control device. Client-side developers will release updates faster than ever to dynamically add support for new devices in the extended local network.”

Imagine!!

�  Your home anticipates your arrival since it’s in contact with your smart phone

�  On arriving home you unlock your door using your smart phone

5

�  Lights and heating are automatically adapted when rooms detect that they are occupied.

�  Control and manage household services such as heating, lighting, blinds, security, entertainment and data

�  Lights and heating automatically turn down when rooms are vacated and everything can be switched off with one button on leaving.

Crazy? ... No!

Potential Experience: Fitness

�  Fitness app connects to running shoes via Bluetooth LE �  Notification received in Hub via Push from a Fitness BBM

Channel �  “Flash Special: Log a 5km+ run in the next 24 hours and get 20% off your

next purchase online” �  Your run is tracked and analyzed using Bluetooth LE and LBS �  Fitness app’s Scoreloop integration notifies user

�  “You’re in 2nd place this week at 21km total! 4km more and you’ll be on top of the leaderboard”

�  Achievement gets posted via Share to social media and with BBM trophy avatar

�  Minimized app motivates you to run more (Active Frames): �  “4km more and you’ll be the winner”

7

Other Potential Experiences!

�  Sports equipment with sensors – how about this Basketball?

8

�  Location aware beacons �  Indoor Navigation (e.g.

Museum Tour) �  In-store marketing/

payment

Limited only by ...

�  ... your imagination �  BlackBerry 10 has all the

capabilities you need to start exploring this area as a developer

�  Let’s take a look in more detail

NFC

We cover NFC in Session JAM803

10

What can I do with NFC? �  Enable users to interact securely and efficiently with their environment

�  Tap to share; Tap to pair; Tap to pay; Tap to access; Tap to…

�  Smart Tags: Tags can give the user information or automate common tasks

�  Tag reading and writing is supported

�  Tag Emulation: Tag functionality can also be replicated by the phone’s NFC antenna

�  Ticketing and Access: Allow users to gain access to workplaces, secure areas, theatres, events, trains, buses etc. �  BlackBerry - first phones to be HID-enabled, replacing security access badges

�  Data Exchange: Exchange pictures, messages or electronic items between devices

�  Automatically configure/connect devices by tapping them together

WiFi Direct

12

13

•  Peer-to-peer Wi-Fi connection without the need for wireless access points (APs)

•  Typically short-lived, application-controlled connections for a specific purpose

•  One device acts as Wi-Fi Direct Group Owner (GO) others are Group Clients

•  Backward compatible with existing Wi-Fi devices (GO looks like an AP to legacy devices)

•  Security is WPA2 Personal using Wi-Fi Protected Setup: Push Button or PIN-based

•  Simply establishes an IP connection on which services can run •  & Share)

Wi-Fi Direct – What is it?

14

•  BlackBerry Tag NFC-initiated file transfer uses Direct for faster performance •  File sharing also offers Wi-Fi Direct

•  Mobile Hotspot operates as Wi-Fi Direct Group Owner •  Saves battery when all clients are Direct-capable

•  DEMO!

Wi-Fi Direct – Use Cases

Bluetooth Low Energy
