Features of This Prototype
Smart Helmet addresses the following use cases:
1. Detect falling biker and trigger appropriate actions
o Create audible alarm and visual flashing lights to seek attention by
alerting nearby people
o Send emails/texts to Parents/Guardians
2. Group riding monitor:
o Alert group, Parents if one or more bikers veer off from each other by
10 feet
o Signal the fellow bikers with audio alarm to alert them about
slowing/missing biker
3. Proximity detector:
o If Vehicle is less than 3 feet away from biker, send audio alarm and
visual flashing lights
4. Visibility in Low-light:
o Increase brightness of front/rear lighting as it gets dark
Proposed solution Proof-of-Concept (POC)
• POC performed using "Circuit Express"
Video recording to
• Simulated the following scenarios: be attached
o Detect falling biker and trigger audible
alarm and flash LED lights
o Group riding monitor - Alert group if one
bikers veers off from each other
o Proximity detector: If Object is less than
1 feet away from biker, send audio alarm
and visual flashing lights
o Visibility in Low-light:lncrease brightness
of Circuit express as it gets dark
Pros and Cons of Solution
Pros:
• Makes biking safer through technology
• Encourages group biking activity
• Helps make Cars/trucks be more responsible while driving
• More exercise for kids
• Safety factor for many circumstances
Gons:
• Technology needs to be proven out
• Evaluate business case to make concept production worthy
Cost of Solution
Cost of standard helmet: S30-S40
Cost of Circuit express: $25
Total cost of Smart helmet: Less than $100
Here are the assumptions about the cost:
• Simple model of buying standard helmet and attaching circuit
express
• Coding circuit express to address the identified use cases.
Incremental unit cost of coding = SO
