Real-time multimodal micro-turn voice for chronic illness - studied openly, in the real world.
Patients simply speak; our system generates the exact spoken explanation they need to hear, the visual they need to see, and a clinician-reviewable record. We study how this works in production - and publish what we learn.

Our Research Mission
A living laboratory for human–AI interactivity, open to the field.
Academic and laboratory teams rarely have access to large-scale, longitudinal, multimodal interaction data from real users. LinkaChart operates as a living laboratory: a deployed product used daily by consenting patients with complex chronic illness, so the research community can study real-time micro-turn steering, generative UI, and live agent control in the wild. The product surface we study, Capture, Show, Guide, is one continuous story across three steps: between, during, and after appointments. Our protocols and outputs are deliberately domain-agnostic, designed to be useful well beyond chronic care.
Current Research Focus
Four open questions we are studying.
Steering long-horizon tasks
Extending mid-conversation tool calls (dynamic next-question selection, instant symptom logging) into full micro-turn steering with context injection and live redirection.
The Emperor’s Interface
Orchestrated agents that produce the right spoken explanation and the right visual - charts, symptom timelines, source references - in real time, on top of an open-weights base model.
Real-time multimodal evaluation
Randomized, clinician-blinded head-to-head study comparing the micro-turn Emperor’s Interface against a turn-based baseline, with ablations isolating acoustic features, sentiment signal, and policy specialization.
Longitudinal state & safety
Tracking state integrity, symptom recall, and safety-floor flags across consented patients over a multi-week longitudinal window - not a single-session snapshot.
Outputs will be released publicly on completion.
Three steps, one continuous story
Capture
Generative visual + spoken response.
Show
Structured summary your care team can actually use.
Guide
Doctor's instructions into daily guidance.
Open Research Commitment
Protocols, code, and findings - released openly, under permissive licences.
We view this work as filling a structural gap in the literature: results any researcher can understand, validate, and use - not just specialists. Outputs are released under permissive open licences on completion.
Phase 1
Pilot & protocol
Acoustic feature extraction, prototype steering extensions, clinician rubric pilot with inter-rater reliability testing, and enrollment.
Phase 2
Open release
Comparative study results, Doctor Rubric with IRR calibration process, arXiv pre-print, and peer-review submission.
- Comparative study - micro-turn Emperor’s Interface vs. turn-based baseline, head-to-head, with longitudinal trend over a multi-week window.
- Doctor Rubric - clinician-written, IRR-calibrated scorecard for real-time AI interactivity. Domain-agnostic; usable by any team in any setting.
- Public paper - arXiv pre-print on completion; peer-review submission to follow.
- All research is conducted independently of product roadmap decisions.
- Ethics-reviewed · Patient-centered.
