Cohort 2026 — Hackcessible

The core problem

By the second visit it was clear: the learner could read a clock, but the gap between activities was where the school day became difficult. Standard timetables did not help. Phone-based reminders were not his to carry.

What worked

A quiet pre-warning before each transition. The wristband does the warning while the class teacher continues normally.

What needs more work

The caregiver–teacher handoff. Two adults editing the same schedule introduced conflicts when changes arrived during the day. A future cohort can begin with that learning.

The core problem

The team worked with a 20-year-old non-verbal challenger living at home with his mother. He communicates through gesture and routine. The prototype explored a quiet, predictable structure for the day across the devices around him.

What worked

A consistent bilingual, observational tone helped the different screens feel like one system. The LAN fleet control plane, multi-device synchronization, acknowledgements and offline hold are implemented in the current demo.

What remains pilot scope

GPS, geofence and tag telemetry are simulated. Production Device Owner enforcement, GPS accuracy, hardware tags and provisioning remain pilot work. Bypass resistance is under test.
