Capacitive sensing can be used to measure electrostatic features of a space. Rudimentary capacitive sensing can be blurry. For instance, the resolution of a capacitive sensor generating a simple electric field is not very high, and the response to the simple electric field is also not very high. Using many capacitive sensors and special sets of excitation signals exciting the capacitive sensors, the capacitive sensors can generate specialized electrostatic fields. Because the specialized electrostatic fields provide different views of the space, enhanced inferences can be made from measurements of responses to those specialized electrostatic fields. Selecting certain specialized electrostatic fields can allow capacitive sensors to sense a focused region of the space. Repeating the steps with varied electrostatic fields can allow capacitive sensors to make enhanced inferences for many focused regions of the space, thereby increasing the resolution of capacitive sensing. |
