Sports performance and technique monitoring…

THEN… NOW…


What has brought about this change

in sports performance & technique

monitoring?

2 of the key factors are…


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.


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


Let’s consider the

technology building

blocks required to deliver

these systems


Technology – what are the options?

Wearable device(s)

Wearable

It’s important to remember that there is much more to this than just the wearable

device; you need to consider the whole system

…clearly there are lots of different options and many new ones emerging all the time…


…if you included all these technology components in a single solution you might end

up looking like this…


Does one size fit all?!

Clearly…NO!

…or worse…like this!…



Introduction

Technology options



Example: XelfleX


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…



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…



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…



coach

sports

scientist media

fans

…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



Introduction

Technology options



Example: XelfleX


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…


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.



….also, remember that this is a SYSTEM!

You need to consider the system

architecture right from the beginning…


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


Designing a successful solution: it’s a system

Demanding applications can result in conflicting design requirements.



Introduction

Technology options



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.


The basic principle behind XelfleX is very simple. Optical fibres scatter back a

very well defined amount of light continuously along their lengths

XelfleX

Distance along fibre

Reflected

power


Bending the fibre tightly results in increased scattering and reflection and so

also less scattering beyond the bend

XelfleX

Distance along fibre

Reflected

power


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

Xelflex


INS sensors XelfleX

What is it

measuring?

Absolute limb

orientation / motion

Relative joint

motion

Accuracy? Degree ~10 degree

Importance of fit? High High

Scalable? No Yes

Cost for 1 sensor? Low Medium

Cost for multiple

sensors?

High medium

Integration in

textile?

No Yes

Time to market Ready > 1year of

development
