Heat dissipation is one of the biggest limiting factors for processors running in smart glasses.

True: engineering or industry sources show that heat dissipation (thermal limits) is widely seen as one of the main limits on the computing power that can run in smart or AR glasses. Mostly true: thermal limits are recognised as a major limit but are usually discussed alongside battery or power, with heat ranked a little lower. Mixed: sources disagree on whether heat is a leading limit. Mostly false: heat is a minor factor compared with others such as battery, size or optics, and the claim overstates it. False: sources show heat dissipation is not a significant limit.

   “But once you crossed that Rubicon, you’re actually just throttled on raw ability to create thermal energy on the face. So that’s the major hurdle we have.”

   “The biggest roadblock, he said, is lowering the energy consumption of the hardware, along with reducing the heat that today’s processors emit.”

   “Apple realized while developing the Vision Pro that building AR glasses with sufficient power was not feasible. To work, the glasses would need to provide the full performance of an iPhone with a tenth of its power consumption to keep them from getting too warm.”

   “The glasses form factor can only dissipate so much heat, and it can only accommodate so much battery capacity.”

IEEE Spectrum (E2, 2019) reports that the biggest roadblock for AR glasses is cutting the hardware's energy use together with reducing the heat processors give off. That makes heat a leading limit, but it is named alongside power. MacRumors (E3), drawing on reporting about Apple, also treats heat as a binding limit on AR glasses, though it frames low power consumption as the way to keep the glasses cool. Meta-linked sources (E1, E4) likewise describe thermal output as a major hurdle, alongside battery capacity. Taken together, the sources recognise heat as a major limit that is usually discussed with power or battery, which fits mostly true.
