SENTINEL.
Augmented Reality Glasses for Road Cyclists

Using proximity radars, lights, and an OLED screen, Sentinel provides an integrated HUD that notifies cyclists of approaching hazards, minimizing chances of accidents. The glasses provide directional cues and tailored statistics to riders on a need-to-know basis to limit distraction during rides.

1 in 4riders have suffered an accident or near-accident in the last 90 days.
73%of those accidents involved cars or road hazards.
The ProblemWhat makes cycling dangerous?
High SpeedsLittle time to react at speed.
Road HazardsObstacles appear without warning.
Split-Second CallsMultiple inputs processed at once.
Areas of ImprovementWhere can we make an impact?
Biker FormationVulnerable in blind-spot traffic.
Inconsistent AudiblesPoor rear-pack awareness.
Mental OverloadSensory conflict slows reaction.
The ObjectiveHow can we design a pair of augmented reality glasses that effectively notify users of potential road hazards to prevent accidents?
Feature 01The Radar.

Detects an approaching large mass using rear-facing proximity sensors. Provides directional cues and real-time distance data, allowing riders to anticipate danger before it becomes a crisis.

Feature 02The Lights.

Peripheral LED strips embedded along the lens frame provide ambient hazard alerts without demanding the rider's focused attention. Color and pulse rate communicate urgency at a glance.

Feature 03The Screen.

A compact OLED micro-display sits in the rider's peripheral view, showing speed, cadence, and hazard alerts only when needed — the interface is designed to inform, not distract.

Built, Not ImaginedThe Prototype.
AnatomyDesigned from
the inside out.

Every component in Sentinel earns its place. Eleven parts, each chosen to stay lightweight, peripheral, and invisible until needed. One unified system. Nothing wasted.

01
LidTPU construction, fastened by screws to the main chassis.
02
MagnetsN52 neodymium. Creates the magnetic snap system — 0.4" circular diameter, 5 magnets per chassis.
03
MicrocontrollerLinks together all electronics into a single unified system.
04
Battery2,500 mAh. Up to 10 hours of continuous battery life per charge.
05
RadarDetects large bodies (vehicles) from 100m, oncoming cyclists from 10m. 40° cone of vision.
06
Halo (Chassis)TPU construction. Flexible material allows the frame to conform to the curve of various helmet profiles.
07
OLED Screen128 x 64 px. Projects heads-up statistics from synced cycling equipment directly into view.
08
LensPolarized polycarbonate optic.
09
HUD FilmAdheres to the lens surface to project the OLED display into the rider's field of view.
10
LED StripFixed to the bottom of the frame. Delivers directional hazard warnings sourced from the radar module.
11
BottomAttaches to the underside of the lens, completing the assembly and providing protection via its nose guard.
