A multi-body augmented or virtual reality device is a head-mounted display whose constituent units can be flipped up, e.g., from over the eyes to over the forehead. In a multi-body AR/VR device, thermal problems associated with high processing power are exacerbated by the need to cool down each constituent unit. This disclosure describes techniques that achieve efficient thermal regulation in a multi-body wearable device by establishing a conductive or convective thermal path between the constituent units of the device. The techniques enable a flexible and ergonomic industrial design, and reduce duplicated componentry, weight and cost.
