Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: In an exemplary embodiment, a system for measuring smoke absorption into food products includes a surrogate that reacts to a presence of smoke in air ambient to the surrogate and the food products, the surrogate including an open container of a liquid and a probe in the form of a toroidal conductivity sensor that measures electrical conductivity of the liquid; wherein the electrical conductivity of the liquid increases as smoke is absorbed by the liquid and simultaneously into the food products; and a control that receives a signal from the toroidal conductivity sensor and in response generates a signal and/or a display indicative of the electrical conductivity of the liquid that corresponds to a selected amount of smoke absorption by the food products exposed to the smoke.
