There is currently significant innovation in wearable technology, and particularly in the sports & fitness market. This presentation considers the many different technology options that can be used as building blocks, and the different stakeholder requirements to consider when developing a new wearable technology solution. This presentation was prepared for the Wearable Tech Expo 2015, London.

Sports performance and technique monitoring…
THEN… NOW…

What has brought about this change
in sports performance & technique
monitoring?
2 of the key factors are…

6. 13 March 2015 WEAR15-P-006 v1.06Commercially Confidential
Technology availability
 Components are now available at a cost, size and performance
that makes new products/systems possible…
 …new options are emerging all the time.

7. 13 March 2015 WEAR15-P-006 v1.07Commercially Confidential
Uptake of smartphones reduces the cost of entry for new products/systems…
 The uptake of smartphones means that most
consumers already have part of the system
in their pocket
 Wearable tech systems can effectively ‘piggy
back’ on this existing infrastructure
– Cost benefits
– Data capture is effectively omnipresent

8. 13 March 2015 WEAR15-P-006 v1.08Commercially Confidential
Let’s consider the
technology building
blocks required to deliver
these systems

Technology – what are the options?
Wearable device(s)

It’s important to remember that there is much more to this than just the wearable
device; you need to consider the whole system

…if you included all these technology components in a single solution you might end
up looking like this…

13. 13 March 2015 WEAR15-P-006 v1.013Commercially Confidential
Does one size fit all?!
Clearly…NO!
…or worse…like this!…

 Stakeholder requirements

15. 13 March 2015 WEAR15-P-006 v1.015Commercially Confidential
Clearly one size doesn’t fit all,
and to develop a successful
solution it’s important to consider
the requirements of the
stakeholders who will use and
interact with your product/system

Angle of movement
What are the requirements? What is actually needed?
Technique
Heart rate
Waterproof
Weight
Think about the different requirements for different sports, and what
the athletes want to know…

17. 13 March 2015 WEAR15-P-006 v1.017Commercially Confidential
What are the requirements? What is actually needed?
Accuracy
Cost
Ease of use
Set up time
Data security
Think about the different requirements for athletes at different levels
in sport…from mass market consumers to elite athletes…

18. 13 March 2015 WEAR15-P-006 v1.018Commercially Confidential
What are the requirements? What is actually needed?
coach
sports
scientist
media
fans
Think about the different requirements for the different stakeholders
involved in a single sport.…it’s not just all about the athlete, you
also need to consider…

19. 13 March 2015 WEAR15-P-006 v1.019Commercially Confidential
What are the requirements? What is actually needed?
coach
sports
scientist
media

…also think about the importance of the context of WHEN & HOW the information
will be consumed e.g. what the coach wants to know on the side of the pitch
during a game is different to the information he wants when reviewing the team
performance post-match, or when catching up 1:1 with a player to review
performance over an extended time

21. 13 March 2015 WEAR15-P-006 v1.021Commercially Confidential
We’ve already talked about the
importance of understanding the
requirements of the stakeholders
When designing a successful
solution it is also important to
consider…

22. 13 March 2015 WEAR15-P-006 v1.022Commercially Confidential
What’s your minimum viable product?
I’m not saying you shouldn’t be ambitious, but you should think through what
would be the MVP that would be successful for you. This will allow you to
focus on delivering rather than being distracted by ‘nice to have’ features
which could increase the scope and delay your development.
Designing a successful solution

23. 13 March 2015 WEAR15-P-006 v1.023Commercially Confidential
….also, remember that this is a SYSTEM!
You need to consider the system
architecture right from the beginning…

24. 13 March 2015 WEAR15-P-006 v1.024Commercially Confidential
Changes to one element of the system often affect others.
Understanding this and managing the system architecture are critical.
Designing a successful solution: it’s a system

Demanding applications can result in conflicting design requirements.

Does one size fit all?
 Introduction
 Technology options
 Stakeholder requirements
 Designing a successful solution
 Example: XelfleX
I will use an example of an emerging
wearable technology (Xelflex) to illustrate the
point that one size does not fit all…

XelfleX – making garments inherently smart
 A novel type of ‘smart’ textile that
makes garments inherently smart.
 As a plastic optical fibre based
technology it’s cheap, comfortable,
robust, safe and washable.

28. 13 March 2015 WEAR15-P-006 v1.028Commercially Confidential
The basic principle behind XelfleX is very simple. Optical fibres scatter back a
very well defined amount of light continuously along their lengths

29. 13 March 2015 WEAR15-P-006 v1.029Commercially Confidential
Bending the fibre tightly results in increased scattering and reflection and so
also less scattering beyond the bend

30. 13 March 2015 WEAR15-P-006 v1.030Commercially Confidential
By integrating the fibre into a close-fitting garment, motion of a joint
can change the amount of bending at a defined point in the fibre
