Abstract: Aspects of the disclosure include a non-transitory computer-readable medium storing thereon sequences of computer-executable instructions for automatically identifying underutilized features of an electronic device, the sequences of computer-executable instructions including instructions that instruct at least one processor to determine whether at least one underutilized-feature trigger is satisfied, identify, based on determining that the at least one underutilized-feature trigger is satisfied, at least one underutilized feature of the electronic device, identify the at least one underutilized feature of the electronic device to a user of the electronic device, and store an indication of the identification of the at least one underutilized feature of the electronic device to the user.

Abstract: In a dual-concentric knob, an inner knob acts as a solid ergonomically functional knob for forces below a threshold and collapses into an outer knob for forces above the threshold. In some examples the inner knob also acts as a push button for forces below the threshold. A hand-operated control is mounted on a hub for axial movement between a first position and a second position relative to the hub, a mechanism axially rigidly couples the control to the hub in the first position unless a force greater than a threshold is applied to the control, and a mechanism rotationally couples the control to the hub in both the first and the second positions.
