# sensor capturer
-device capturing sensory experiences beyond audio/video.

+a device that captures sensory experiences beyond what audio and video recording covers — smell, touch, temperature, humidity, spatial orientation. the problem it's solving: you can video a concert, but you can't record how the room smelled or the physical feeling of the crowd. memory research shows these modalities are often the most emotionally salient; losing them means losing the texture of the experience. the device would act as a wearable multimodal logger, capturing a richer slice of lived experience for later recall.
+
+the hardware side is tractable. most of the relevant sensors are cheap and small: gas sensors for rough olfactory capture, temperature/humidity, barometric pressure, accelerometer/gyroscope for motion and orientation. the harder problem is making sense of the data — raw sensor streams aren't interpretable without calibration and context. the interesting approach is pairing the raw sensor data with an LLM-based annotation layer that infers "this was a forest, cold morning, post-rain" from the sensor fingerprint combined with location/time metadata. over time, the system could learn personal sensory associations (this temperature + smell pattern = the beach house).

+connects directly to [[brain-rewinder|brain rewinder]], which explores using sensory triggers to invoke recalled mental states — sensor capturer is the capture side of that loop. [[universal-data-capturer|universal data capturer]] provides the logging and schema infrastructure. [[smell-resetter|smell resetter]] is the adjacent olfactory research thread with deep overlap in mechanism. [[always-on-ai-assistant|always-on AI assistant]] covers the audio-visual capture side, making sensor capturer the complementary hardware for what that misses. [[ppg-biomarker-wearable|PPG biomarker wearable]] and [[emg-bracelet|EMG bracelet]] are adjacent wearable-sensing ideas that could share a hardware platform.
