## Background
FIELD
The present disclosure relates generally to the field of call status and control. More particularly, the present disclosure relates to headset call status and control.
BACKGROUND
This background section is provided for the purpose of generally describing the context of the disclosure. Work of the presently named inventor(s), to the extent the work is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
To meet the demands of conducting business professionally in a mobile environment, mobile professionals seek out premium headsets with sophisticated functions such as microphone mute, volume, answer/end call, and even voice commands to help manage the quality of their communications. User interfaces to control these functions typically require physical buttons or a list of voice commands that the wearer can speak, usually stored in the firmware of the headset.
The lack of a visual user interface for these functions while wearing the headset causes anxiety to the user. Users become uncertain of the microphone mute status of the call, or miss critical information when on a call in loud environments, because they can't find the buttons to change call volume in the headset.
Previous solutions fall into two categories of call control interfaces. With a physical headset user interface, buttons on the headset itself control the microphone mute status of a call, volume of the call, redial, call answer/end ability, and the like. With a PC/Mobile graphical user interface, voice controls stored in the headset firmware allow hands-free voice control including but not limited to pairing the device, answering/ending a call, recognizing and calling a stored contact by name, querying what other voice commands are available with “what can I say?” and the like. Selectable icons to control the call status (microphone mute, volume, answer/end) are typically found in the user interface of softphone clients or in the telephony client of a mobile device/PC.

DETAILED DESCRIPTION
Embodiments of the present disclosure provide wearable devices for headset status and control. In the described embodiments the wearable devices are smartwatches, that is, wristwatches that include processors, output devices such as displays, speakers, and haptic devices, user-operable controls, and wireless transceivers. However the techniques described herein are applicable to other wearable devices as well. For example the wearable devices can include wristbands, rings, necklaces, garments, and the like.
Such a wrist-worn call control center for headset functions provides users with the trust they need during important mobile conversations. The smartwatch and headset may be synchronized at all times. In other words, if the user mutes the headset microphone from the headset the smart watch gives a visual representation that the user is on microphone mute. Then if the user unmutes the headset microphone from the smart watch, the headset microphone comes off mute. The smartwatch then acts not just as a command/control vehicle for the headset functions but also an in-line-of-sight visual representation of the call state.
End users now have a visual user interface for functions that previously were difficult to find and use but still did not give users reassurance that the selected function was being effectively carried out. This solution eliminates the anxiety users feel on important calls by providing visual reassurance of the call state.
Other features are contemplated as well.
