What you see above is not an alien visitor but rather a normal human wearing a prototype augmented reality welding mask. This system, dubbed ‘MannVis welding helmet’ by its creators, allows welders to see their work with an incredible level of detail that far surpasses what the human eye is capable of. It’s great to finally see a practical application of augmented reality when there are so many useless and novel augmented reality demos out there. The augmented reality welding system is not only useful for helping experienced welders to do better work, it is also quite useful for teaching welding techniques to students of the skill.
