Complex wakeup gesture framework

A system comprising:

• an input device comprising:
• a plurality of sensor electrodes configured to acquire sensing signals, and
• a processing system configured to:
• determine, from the sensing signals, a first positional information corresponding to a first gesture while a host device is in low power mode,
• determine, based on the first positional information and while the host device is in the low power mode, that the first gesture is deliberate input, and
• send, in response to determining that the first gesture is deliberate input, a wake signal to the host device to switch the host device out of the low power mode, and
• send the first positional information to the host device after the host device receives the wake signal;
• and
• a host device configured to:
• switch out of the low power mode based on the wake signal, and
• analyze the first positional information based on receiving the first positional information.

A method for sensing comprising:

• determining a first positional information corresponding to a first gesture while a host device is in low power mode;
• determining, based on the first positional information and while the host device is in the low power mode, that the first gesture is deliberate input;
• sending, in response to determining that the first gesture is deliberate input, a wake signal to the host device to switch the host device out of the low power mode, and
• sending the first positional information to the host device after the host device receives the wake signal.
