Emergency SOS

I’m here. Stay calm. Are you injured or in danger?

Yes, I'm hurt.

I’ll alert emergency services.

Be quick.

Can you tell me your exact location?

Not exact, a place in forest.

I’ll identify as no exact location, change to GPS searching.

When is the emergency coming?

Emergency services have been notified and are on their way. Can you move to a safer area?

Yes, I can.

Hi, Tess.

Yes, Emma. How can I help you?

Find Hanna's location on the trail.

Hannah is currently 0.3 miles ahead on the Pine Trail near the next turn.

Would you like me to send her a message?

Yes, tell her I'm catching up.

Message sent to Hannah

Hannah replied ‘Great! I’ll wait for you at the big oak tree ahead.’

Head straight for 0.3 miles to reach the big oak tree where Hannah is waiting.

We designed Trek for sports enthusiasts who seek hands-free, intelligent navigation. After testing different user needs, we selected Emma, a tech-savvy cyclist, as our primary persona to ensure real-time updates, seamless interaction, and safety support on the trails.

Trek is the name of our app. It reflects outdoor adventure, and the journey of exploration.  


Tess is our voice AI. Soft, and memorable, Tess always ready when you need support.

Next Steps

This project introduces voice-enabled navigation for outdoor sports, but more real-world testing is needed to validate its usability and reliability in dynamic conditions.

For next steps, I plan to expand user testing across diverse ride scenarios and conduct more competitive analysis to benchmark current features. These insights will guide refinements in route sharing, adaptive voice feedback, and group safety alerts.

With continued iteration, Trek aims to become a more responsive, accessible, and context-aware companion for outdoor athletes.
