Abstract: Examples are disclosed that relate to methods, computing devices, and head-mounted display (HMD) devices for regulating a surface temperature of a device. In one example, a method comprises determining the surface temperature of a surface of the device, determining an energy accumulator value indicating cumulative energy received by a user via the surface of the device, and using a dynamic temperature limit function to calculate a temperature limit as a function of the energy accumulator value. The method also comprises comparing the surface temperature to the temperature limit. When the surface temperature has not reached the temperature limit, the method comprises incrementing the energy accumulator value. When the surface temperature has reached the temperature limit, the method comprises initiating a thermal mitigation action to cool the surface.

Abstract: A system for increasing the temperature of a display element includes a heat source configured to perform a user experience function independent of generating heat. The system also includes a thermally conductive element that is coupled to the heat source and is positioned proximate to the display element, forming a thermally conductive path between the heat source and the display element. A method for increasing the temperature of a display element includes generating heat by operating a heat source to perform a user experience function independent of generating heat, and dispersing the heat from the heat source to the display element via a thermally conductive path formed by a thermally conductive element coupled to the heat source and positioned proximate to the display element.
