Lumina: Speak Without a Sound
Lumina presents a forearm- or jaw-worn band that reads subvocal muscle activity and turns it into computer commands.
- For
- People exploring silent computer input and wearable interfaces
- Worth noticing
- The stated signal path uses eight differential channels sampled at 1 kHz, with raw data kept on-device.
Field notes
The proposed system combines a dry electrode array with photoplethysmography and a nine-axis IMU, then runs decoding inside the wearable rather than sending raw signals to a server. The runtime is described as translating personal muscle patterns into phonemes, words, and actions that look like ordinary host inputs. The homepage gives technical parameters, including eight differential channels at 1 kHz, but does not show a public demo or indicate that the hardware is generally available.
