Memorable
Capture a moment. Find it with a question.
Memorable is a wearable memory aid for people who want to recall conversations, products and people they meet. A pendant or keychain captures media with a button press, then makes it searchable through natural language.

01 / The interaction
How can recall feel as simple as asking?
A button press captures an image and records audio. The device stores the media, then transfers it to a phone or local server. Processing creates embeddings that let the user retrieve relevant memories through conversation.
The complete flow has been demonstrated with the wearable and mobile application.
02 / Research & engineering
What went into it.
Wearable electronics
An ESP32-S3 board brings together the camera, microphone, SD storage, button and touchscreen display.
Physical interaction
A wearable enclosure supports pendant or keychain use. Press and hold to capture an image and record audio; release to save the moment.
Capture & sync
Stored images, audio and metadata move to the companion app for processing. BLE discovery supports the nearby-device interaction.
Multimodal processing
The phone runs a Gemma model for conversational and multimodal processing, including embedding generation.
Retrieval experience
A functional mobile application connects captured media to natural-language queries.
Local compute
A SpacemiT RISC-V processing path is planned alongside the separate trusted-execution research.
03 / Progress
Built. Tested. Next.
Hardware and enclosure
The custom board, input components, display and wearable enclosure form the current prototype.
End-to-end recall
A button press can be followed through capture, transfer, processing and retrieval in the mobile app.
Second hardware iteration
Revise the circuit to address the limitations found in the first prototype.
Reliability and testing
Improve firmware robustness and rigorously test the application and physical assembly.
The prototype requires careful operation. Physical construction, firmware and application reliability still need substantial engineering and testing.
