LUCID

PHONE-BASED HEAD-INJURY SUPPORT

A clearer
next step after
a head injury.

A familiar phone call. Structured questions. A conversation that continues when it matters.

LUCID explores how AI could help families recognize potential concerns and follow changes over time — without an app or internet on the caller’s phone.

Functional prototype. Not a live medical service.

THE CONVERSATION CONTINUES
ONE FAMILIAR INTERFACE

Just a phone call.

Start with a conversation

Guided questions, in a voice interface.

Pick up where you left off

Context can survive a dropped call.

Keep the next check in view

Follow-up is part of the design.

WORKFLOW AT A GLANCE

01 / WHY LUCID

The first conversation
should not be
the last check.

After a possible head injury, a family needs to know what to do next. Finding guidance — and keeping track of what changes — can be difficult.

We’re focused on the gap between an injury and reaching care: making the next step easier to understand through an interface people already know. A phone conversation can gather context, continue after an interruption, and make room for a follow-up.

How the idea began

02 / HOW IT WORKS

A call. A conversation.
A way to stay connected.

Designed around the phone people already have — and the reality that a connection may not last.

01

A normal phone call.

An ordinary telephone, including a landline. No app or caller-side internet. The service backend still needs infrastructure.

02

Structured questions.

Conversational AI gathers context through guided questions, with explicit triage and escalation rules.

03

A conversation that continues.

Persistent context supports an interrupted call. Automated follow-up is designed to check for changes over time.

04

A path toward help.

The prototype demonstrates escalation prompts and routing where configured. Local referral pathways and clinical oversight are needed before use.

Language is part of access. Multilingual interaction is part of the prototype. Language needs and performance must be established for each intended setting.

03 / LUCID IN CONVERSATION

One conversation.
Even across calls.

From our recorded demo: a caller asks for clarification, LUCID remembers an interrupted call, and a follow-up brings the conversation back when it matters.

    Hi, I’m LUCID. I’ll ask a few quick questions about the person who hit their head. Did they lose consciousness?

The caller can ask for clarification and keep the conversation going.

The first call

Ask naturally

  1. LUCID

    Hi, I’m LUCID. I’ll ask a few quick questions about the person who hit their head. Did they lose consciousness?

  2. CALLER

    Yes, they did.

  3. LUCID

    Is one side of their body weak, numb, drooping, or not moving normally?

  4. CALLER

    How could I test that? I’m not really sure.

  5. LUCID

    Have them squeeze your hands with both hands.

  6. CALLER

    It seems like it’s pretty even pressure. Is there any other test I can do?

  7. LUCID

    Ask them to lift both arms straight out in front of them. Does either arm drift down or look different?

  8. CALLER

    They look the same.

After a dropped call

Pick up again

  1. The caller reconnects after the call drops.
  2. LUCID

    The call dropped before we finished. You said they lost consciousness, with no weakness on one side. Is that still correct? Has anything changed?

  3. CALLER

    That’s still right. Nothing has changed.

  4. LUCID

    I’ll call back to check again.

  5. CALLER

    Thank you. Goodbye.

Later · time compressed

Check back

  1. Later, an incoming call from LUCID.
  2. LUCID

    Hi, it’s LUCID calling back about the head injury. Have they vomited more than once since the injury?

  3. CALLER

    They did vomit one more time.

  4. LUCID

    They need to get to a hospital now.

  5. CALLER

    Understood.

04 / OUR STORY

How the idea is taking shape.

A question from the hackathon led to a working prototype. We’re now exploring what it would take to adapt that approach with local partners.

  1. 01 / THE STARTING POINT

    Knowing when to seek help.

    At the 2026 mission:BRAIN hackathon, a fictional case in rural Gilgit-Baltistan, Pakistan, described a family facing uncertainty after a head injury and a difficult journey to care. We focused on one gap: how could they recognize the need for help before reaching a specialist?

  2. 02 / WHAT WE BUILT

    A conversation that continues.

    Our response was LUCID: a functional conversational AI prototype using an ordinary phone call for guided questions, remembered context, and follow-up. The project won first place at the hackathon.

  3. 03 / WHAT WE’RE EXPLORING

    A locally shaped next step.

    With Glial Initiative, we’re using the prototype as the starting point for a Nigeria-specific proposal for Wema Hackaholics’ Social Impact track. Local research will shape what needs to change, from language and telephone access to referral pathways and the operating model.

Local knowledge comes first.

The immediate work is an implementation and sustainability proposal, supported by an adapted demonstration.

LUCID develops the software. Glial contributes local research, community engagement, and stakeholder introductions. Both teams shape the operating and funding model.

  1. Who would use it, and in which languages?
  2. How would calls connect to local care and referral pathways?
  3. What would evaluation, operation, and funding require?

Clinical review and evaluation planning are needed before deciding whether to pursue a supervised pilot.

05 / THE TEAM

A small team.
A practical question.

LUCID was created by three University of Utah students at the 2026 mission:BRAIN hackathon.

A FEW ANSWERS

Where things stand.

Is LUCID available for medical use?

No. It is a functional proof of concept, not a live or clinically validated medical service. This website explains the project; it does not provide medical assessment.

Does it require a smartphone or internet?

The intended caller interface is a normal phone call, including from a landline. The caller does not need an app or mobile internet. The backend still requires computing and telecommunications infrastructure.

Has LUCID been used with patients?

No clinical field deployment or patient-facing service is established. The Pakistan origin is a fictional hackathon case. The proposed Nigeria work concerns local research, planning, and prototype adaptation; a community or pilot site has not been selected.

Which languages does it support?

Multilingual interaction is part of the prototype. The languages needed for a Nigerian setting and their performance will be assessed with local input.

How can clinicians or community organizations contribute?

We welcome conversations about local needs, language, referral pathways, and responsible evaluation. You can contact Walter using the link below. No funded pilot or formal partner program is established.
