We wanted:

Motivations

➔ Something that would give us each a different focus

➔ Something that’s new

➔ Something that’s cool

Page 7: Floe - Simon Fraser University · Funding Projected Costs Final Expenditure Item Cost Item Cost ESSEF: $513.00 2 x BLE SoC nRF52 Dev-kit $230.00 2 x BLE SoC nRF52 Dev-kit $171.31

What are we trying to solve?

The Problem

➔ Limitations of exclusively qualitative feedback

➔ Lack of products in the market offering real-time performance feedback

➔ Lack of products in the market offering balance metrics in an athletic environment
