Embodiment Construction

[0032] Examples are described herein in the context of devices, systems, and methods for capturing acceleration of a device while vibrating by using an internal microphone of the device. Those of ordinary skill in the art will appreciate that the following description is exemplary only and is not intended to be limiting in any way. Reference will now be made in detail to example embodiments illustrated in the accompanying drawings. The same reference designators will be used throughout the drawings and the following description to refer to the same or similar items.

[0033] In the interest of clarity, not all of the routine features of the examples described herein are shown and described. Of course, it should be understood that in the development of any such actual implementation, many implementation-specific decisions must be made in order to achieve the developer's specific goals (for example, compliance with application-related and business-related constraints), and that...

Abstract

The invention relates to systems and methods for determining a device's acceleration using its internal microphone. Examples of devices, systems, and methods for estimating a portable computing device's acceleration when vibrating by using its internal microphone are disclosed. In one example, a portable computing device has a haptic output device that outputs a haptic effect causing the portablecomputing device to vibrate. An audio signal from a microphone in the portable computing device is captured while the portable computing device vibrates because of the haptic effect being output. Theaudio signal can be used to estimate the acceleration of the portable computing device caused by the output of the haptic effect.

Description

technical field [0001] The present application generally relates to determining the acceleration of a portable device when vibrating. Background technique [0002] When an actuator in a portable device is actuated, the portable device often vibrates, causing the portable device to move. Traditionally, external accelerometers have been attached to portable devices to measure acceleration signals generated when the portable device vibrates. Of course, this requires the use of an external accelerometer, which may be inefficient and impractical in certain situations. For example, it is inefficient and impractical to constantly attach an external accelerometer to a portable device. Internal accelerometers in portable devices are also used to measure acceleration signals generated when the portable device vibrates. However, this requires many iterations to estimate the acceleration of the portable device when vibrating. Additionally, internal accelerometers in portable devices...
