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

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

…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

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…
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

….also, remember that this is a SYSTEM! You need to consider the system
architecture right from the beginning…
13 March 2015 WEAR15-P-006 v1.024Commercially Confidential
Designing a successful solution: it’s a system
Changes to one element of the system often affect others.
Understanding this and managing the system architecture are critical.

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
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.
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

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

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
