Call capabilities, e.g., using WiFi/LTE, are now available in devices other than phones. For example, a headset can be built with wireless (WiFi/LTE) communication abilities. Such a headset operates in standalone fashion, e.g., without control or short-range communication (e.g., Bluetooth) with a device such as a smartphone or tablet. The headset can be operated in a hands-free manner and can present advantages over the headset-and-smartphone combination. However, a standalone headset operates without the visual cues that are available on the screen of a device such as a phone or tablet. This disclosure describes using a haptic mechanism to convey headset and/or communication status to a wearer of a standalone headset.
