Daedalus
Real-time assistive navigation and memory support — designed for the people most let down by AI that sounds certain when it shouldn't be.
What Daedalus does
Daedalus is a real-time assistive navigation system. Using the device's camera, it continuously analyses the environment and delivers spoken guidance — but not indiscriminately. The system is designed to interrupt only when something matters, narrate only what's relevant, and always signal its level of certainty.
For carers of people living with dementia, the narration log is as important as the real-time output. Authorised family members or care professionals can review what was said, when, and how confidently — providing a factual record that can inform care discussions without functioning as a surveillance tool.
Daedalus serves blind and low-vision users, people with cognitive challenges including dementia and Alzheimer's, children learning environments independently, and anyone who needs a navigation aid that's honest about the limits of its perception.
Core capabilities
Hazard-first interruption
Stairs, drop-offs, obstacles, and other physical hazards trigger immediate speech regardless of any ongoing narration. Safety preempts context.
Confidence-calibrated speech
High-confidence detections use clear, direct language. Lower-confidence observations are explicitly hedged — "there may be" rather than "there is." The system never feigns certainty.
Narration rate limiting
A configurable speech budget per time window prevents information overload. Users with memory or attention challenges are not flooded; only the most relevant observations surface.
Secure narration log
Every spoken output is timestamped and stored in a tamper-evident log. Authorised caregivers — and only they — can review what was said and when. Logs can be shared with care teams or healthcare providers.
Memory support
Context-aware reminders can surface in appropriate environments — where objects were last seen, daily routines, upcoming items — supporting independence for users with cognitive challenges.
Caregiver visibility
A dedicated review interface shows narration history with timestamps and confidence indicators, enabling informed conversations about care without real-time monitoring.
How it works
-
Continuous environment scanning
The device camera feeds a real-time perception pipeline. Objects, surfaces, and spatial relationships are detected and classified on-device where possible to minimise latency and protect privacy.
-
Hazard triage
Detected elements are classified by hazard priority. High-priority hazards (stairs, drop-offs, sudden obstacles) interrupt any ongoing narration immediately. Lower-priority context enters a relevance queue.
-
Confidence scoring and language selection
Each detection carries a confidence score. The narration engine selects language appropriate to that score — certain, hedged, or explicitly uncertain — before composing the spoken output.
-
Rate-limited speech delivery
The speech budget manager checks whether the narration quota for the current window is available. Queued context is prioritised by relevance and delivered within the configured rate limits.
-
Secure log write
Every spoken output is appended to the narration log with a timestamp, confidence band, and hazard classification. The log is encrypted and access-controlled per the caregiver permissions configuration.
Who uses Daedalus
Blind and low-vision users
Independent navigation with real-time environmental description — honest about uncertainty, quiet when silence is more useful than noise.
Dementia and Alzheimer's care
Gentle contextual reminders and orientation support, with caregiver-accessible logs that surface what was said without enabling passive surveillance.
Children learning environments
Age-appropriate navigation guidance as children explore independently for the first time — with parent visibility into narration history.
Cognitive and memory challenges
Rate-limited, priority-filtered narration designed for users who benefit from structured information delivery rather than a continuous audio stream.
