IntelliSpace Memento – Enhancing Qualitative Data Capture in Emergency Care

Challenge provided by Philips Experience Design Fellow designers:

Iris Bataille, Jaimy de Kok, Wisse Raaijmakers & Katie Verschueren

Project overview

In emergency medical services (EMS), there’s a constant tension between treating the patient and documenting the care process. EMS providers must record critical information for hospital handover and legal reporting—yet current methods are inefficient (e.g., writing on gloves or post-event reporting), leading to data loss and increased cognitive load.

🎯 Design Goal
Create a low-effort, intuitive way to help EMS personnel document qualitative data in the moment, without compromising patient care.

My role

Conducted user research and need framing
Co-led ideation and concept development
Designed scenario-based interactions
Created data visualization prototypes for reporting

Design process

Philips’ Cocreate process [1] was used for this project to first discover the design context, then frame the project focus, followed by an ideation on possible solutions, and was finished by building the user story.

Discover

First, we explored the design context by familiarizing ourselves with current data collection and reporting methods, as well as by creating a customer journey of the EMS provider’s reporting process.

Emotions shown in the user journey map are inferred from scenario-based design and supported by EMS literature and attention-demand theories. While not grounded in direct fieldwork, they reflect common cognitive states in high-pressure healthcare contexts and helped guide design decisions for IntelliSpace Memento.

Frame

The design challenge was further narrowed down to focus on supporting EMS providers in capturing the qualitative data that they cannot measure with existing devices, such as how the patient looks and behaves. We then carried out the design challenge:

Ideate

In this phase, we drew inspiration from Hassenzahl’s Basic Human Needs model to guide our design direction. Through individual brainstorming and reflection, we identified two core needs that are especially relevant to EMS providers: autonomy–independence and competency–effectance.

To translate these needs into concrete ideas, we began with individual brainstorming sessions, where each team member explored different interaction concepts and wearable forms. We then shared and discussed these ideas collectively, combining the strongest aspects into one coherent direction.

Throughout the process, we evaluated each concept based on how well it supported autonomy and competence in high-pressure EMS environments — for example, by enabling intuitive interaction, minimizing cognitive load, and allowing EMS providers to stay in control without distraction.

Build

The final concept brings together two key components that work seamlessly across EMS workflows:

A wearable device for fast, attention-light voice capture
An AI-enhanced platform for processing and visualizing both qualitative and quantitative data

Wearable device

The device uses a mechanical button interaction to reduce accidental input.
Pressing the green button starts recording: the red button pops out, the LED ring turns red, and the display switches to an audio waveform.

Pressing the red button stops recording: the green button pops out again, the LED turns off, and the clock interface returns.

This flow ensures that EMS users receive clear visual and tactile feedback at each stage — supporting fast and confident operation even under pressure.

AI-powered dashboard

In our concept, the AI system is just as essential as the physical device. While the Intellispace Memento wearable captures qualitative data (such as voice memos), the AI combines this with quantitative data (e.g., vital signs from medical equipment) to generate a meaningful visual overview.

This overview is displayed on the Philips Intellispace Connect platform, making it accessible on a wide range of devices for EMS providers in the field. Importantly, access is restricted to EMS personnel only — not hospital staff — to respect privacy and ethical guidelines.

Reflect

It was concluded that the Momentum ecosystem supports EMS providers in fast & easy data documentation and clear & effective reporting. Through this solution, EMS providers can accurately report information in-the-moment, while keeping their attention to the patient.

Several recommendations for future work have been formulated, such as iterating on the recording interactions and further co-designing this system in collaboration with medical professionals.
