Design a campus safety and emergency response app for university students

Design a mobile campus safety and emergency assistance app for university students walking home late at night or experiencing emergencies on a large collegiate campus.

Context

Blue emergency light poles across campus are fixed in place, and dialing 911 takes critical seconds while failing to broadcast precise building/floor coordinates to campus police.

Clarifying questions to ask first

• Does the app integrate directly with university campus police dispatch CAD systems? (Yes).
• How do we prevent accidental false alarms? (5-second countdown with gentle vibration cancel).

How to approach it

1. Student Personas & Scenarios: The Late-Night Library Commuter (walking through dark quad feeling followed), The Student in Immediate Danger (needs silent discreet SOS), The Bystander (wants to report an incident anonymously)
2. Design Core Emergency Features:
3. 1. "Virtual Campus SafeWalk Escort" (Select destination -> friends or campus security monitor your real-time walking route until safe arrival; triggers alert if stationary for 60s or off-path)
4. 2. "Silent Discreet SOS" (Press power button 3 times in pocket to trigger silent campus police dispatch with live microphone audio stream and sub-meter indoor GPS pin)
5. 3. Emergency Blue-Light Beacon Route Optimizer (Navigation maps routes that stay along well-lit paths with active security cameras)
6. 4. Anonymous Tip Reporting with photo/video upload

Framework: Campus Safety Scenarios & Fear Analysis -> Discreet Trigger Mechanics -> Virtual Walk Escort System -> Campus Police Dispatch Integration -> Safety Metrics

Sample answer

• Students in danger cannot pull out a bright phone screen to unlock and tap 3 buttons; silent physical pocket triggers save lives
• Virtual friend escorts provide peace of mind during everyday late-night library walks

1. MVP: Virtual SafeWalk GPS escort with friend/security sync, 3-click power button silent SOS, well-lit campus routing map, and 1-tap emergency dial with instant indoor building telemetry

Executive design: A campus safety ecosystem featuring virtual friend-escort walk tracking, well-lit route navigation, and silent in-pocket SOS triggers connected directly to campus police dispatch.

What interviewers look for
