Augmented Reality (AR) has been studied for more than 20 years. Nowadays we can see a lot of AR applications such as PokemonGO. Some people think that AR technologies are almost completed and it has moved to a practical phase. But it is not true because current AR applications are not ideal style of AR. AR researchers still have to make the next breakthrough. In this talk, I would like to introduce my past works on AR and then explain my idea about what AR researchers have to do for the next breakthrough. After that I will briefly talk about my current research works which I am expecting to make the next breakthrough for AR.
