Many systems may accept user input to facilitate operation. For example, users may provide input to control home automation systems, enter orders with an online merchant, and so forth. These systems benefit from the presence of user devices to accept input. By producing low cost and robust user input devices, the user devices may be more widely deployed, resulting in user input being more easily acquired in a fashion which is convenient to the user.
While implementations are described herein by way of example, those skilled in the art will recognize that the implementations are not limited to the examples or figures described. It should be understood that the figures and detailed description thereto are not intended to limit implementations to the particular form disclosed but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope as defined by the appended claims. The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description or the claims. As used throughout this application, the word “may” is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words “include,” “including,” and “includes” mean including, but not limited to.
