Abstract: A computer-implemented method is disclosed. The method includes: displaying, on a touch-sensitive display of an electronic device, an indicated value and an annulus having a base segment and a highlighted segment, wherein points along a circumference of the annulus are associated with values between a base amount and a maximum amount and wherein a size of the highlighted segment is based on the indicated value; receiving, via the touch-sensitive display, a first value-adjusting input comprising a tap operation; and in response to receiving the first value-adjusting input, adjusting at least one of the base amount or the maximum amount for causing a range of the annulus to be changed, wherein a proportion of the annulus represented by the highlighted segment corresponds to a proportion of the range represented by the indicated value.

Abstract: Methods and devices are provided for receiving, displaying and adjusting user input through a wearable device. An indicated value and an annulus are displayed on a touch-sensitive display of the wearable device. The annulus has a base segment and a highlighted segment. The highlighted segment begins at an origin of the annulus and extends to a first position of the annulus. The size of the highlighted segment corresponds to the indicated value. A first value-adjusting input is received at the touch-sensitive display. The first value-adjusting input includes one or both of a drag operation and a tap operation. The indicated value and the size of the highlighted segment are adjusted in accordance with the first value-adjusting input, such that the proportion of the annulus represented by the highlighted segment corresponds to a proportion of a difference between a base amount and a maximum amount represented by the indicated value.
