Virtual assistant activation

This invention describes a way to activate a virtual assistant on an electronic device. Instead of just saying a trigger word, the device first needs to be physically lifted while its screen is off. Once the device detects this specific lifting motion, it then starts listening for a spoken trigger word to launch the virtual assistant. The claims specify that the lifting can be measured by its amount or smoothness using the device's accelerometer.

Why it matters: Filed before always-on, low-power speech recognition and sensor processing were as mature. These advancements make the specific 'display off' activation more practical now, reducing battery drain for continuous monitoring.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateSoftware logic, accelerometer, speech recognition
