What is the Continua Health Alliance
 Non-profit alliance of >200 companies have
selected the standards that are most suitable to
the health applications they support
 Version 1 selected Bluetooth as the wireless
standard
 Version 2 will use Bluetooth Low Energy
 The alliance is supporting efforts to roll out health
technology on mobile phone platforms
Mobile connectivity for health

How will it work in practice?

9. © Cambridge Silicon Radio 2010
Bluetooth low energy is optimised to provide mobile health
 The seeds of success have been planted in the spec
 Truly low power, low power connection to the mobile phone
 Bluetooth low energy advertising is a powerful tool
 Any accessory can advertise the services that it can offer
I am a weight scale

10. © Cambridge Silicon Radio 2010
Powerful mechanisms exist in the protocol
 Any device can listen to the adverts
There is a weight scale available

11. © Cambridge Silicon Radio 2010
Powerful mechanisms exist in the protocol
 The device can enquire about the capabilities of the
accessory
What attributes do you have?

12. © Cambridge Silicon Radio 2010
Powerful mechanisms exist in the protocol
 The accessory will report a list of its capabilities (attributes)
Here is a list

13. © Cambridge Silicon Radio 2010
Enables exploration of services
 The device can search for apps that can understand that
accessory
What apps support this accessory?

14. © Cambridge Silicon Radio 2010
Customised applications
 The device can offer the user a choice of applications
Which app would you like?

15. © Cambridge Silicon Radio 2010
Creates a rich UI for simple devices
 Once installed the user can configure the accessory using
a simple UI
– The device can have a lot more capability without a complex UI
– E.g. Set User names and Ids for multiple users

16. © Cambridge Silicon Radio 2010
One device can be used for many services
 Once connected the accessory can have access to web
information and services
– Fitness training
– Weight management
– Chronic disease management

17. © Cambridge Silicon Radio 2010
Web connected accessories
 Once set up the accessory will have the power of the web

18. © Cambridge Silicon Radio 2010
Web connected accessories
 Once set up the accessory will have the power of the web
 A weight scale is now part of your personal Health
management service

What opportunities does this create?

20. © Cambridge Silicon Radio 2010
Revenue opportunities
 The mobile maker doesn't need to understand the
applications
 The accessory maker doesn't need to understand the
applications
 The app developer can create powerful health and fitness
services with engaging user experience
 Generate new revenue for each provider
– Network operator – services, and loyalty
– Innovator – apps
– Handset maker – higher margin and loyalty
– Accessory maker – hardware (app share)
