4. 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.”

5. Imagine!!
Ÿ Your home anticipates your arrival since it’s in
contact with your smart phone
Ÿ On arriving home you unlock your door using
your smart phone
5
Ÿ Lights and heating are automatically adapted when rooms
detect that they are occupied.
Ÿ Control and manage household services such as heating,
lighting, blinds, security, entertainment and data
Ÿ Lights and heating automatically turn down when rooms
are vacated and everything can be switched off with one
button on leaving.

6. Crazy? ... No!

7. Potential Experience: Fitness
Ÿ Fitness app connects to running shoes via Bluetooth LE
Ÿ 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”
Ÿ Your run is tracked and analyzed using Bluetooth LE and LBS
Ÿ 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”
Ÿ Achievement gets posted via Share to social media and with
BBM trophy avatar
Ÿ Minimized app motivates you to run more (Active Frames):
„ “4km more and you’ll be the winner”

8. Other Potential Experiences!
Ÿ Sports equipment
with sensors –
how about this
Basketball?

Ÿ Location aware beacons
Ÿ Indoor Navigation (e.g.
Museum Tour)
Ÿ In-store marketing/
payment

9. Limited only by ...
Ÿ ... your imagination
Ÿ BlackBerry 10 has all the
capabilities you need to start
exploring this area as a
developer
Ÿ Let’s take a look in more detail

10. NFC
We cover NFC in Session JAM803
10

11. What can I do with NFC?
Ÿ Enable users to interact securely and efficiently with their environment
Ÿ Tap to share; Tap to pair; Tap to pay; Tap to access; Tap to…
Ÿ Smart Tags: Tags can give the user information or automate common tasks
„ Tag reading and writing is supported
Ÿ Tag Emulation: Tag functionality can also be replicated by the phone’s NFC antenna
Ÿ 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
Ÿ Data Exchange: Exchange pictures, messages or electronic items between devices
„ Automatically configure/connect devices by tapping them together

12. WiFi Direct
12

13. 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. 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!
