<caption><image_53>The image shows a man standing in front of a blackboard in a classroom. He is wearing a blue t-shirt and is writing on the blackboard with white chalk. The blackboard is green and there are various mathematical equations and diagrams written on it. The equations appear to be related to solving a problem, as there is a red circle on the left side of the board and a whiteboard on the right side. The man is holding a white chalk in his right hand and appears to be writing on it with it.</caption><transcript><audio_54>get down the level of accuracy that we would like which i should point out the goal is sub millimeter accuracy</transcript><caption><image_55>The image shows a man standing in front of a green chalkboard in a classroom. He is wearing a blue t-shirt with a logo on it and has a surprised expression on his face. He has his hand on his forehead and is making a peace sign with his index finger. On the chalkboard behind him, there are various mathematical equations and formulas written in white chalk. The equations are written in different colors and sizes, and the formulas appear to be related to mathematics. The man appears to be giving a presentation or explaining something to the viewer.</caption><transcript><audio_56>why is the goal some millimeter accuracy well if you have very large deviations it's quite perceptible you know if i'm if i put on a virtual reality headset and i start seeing the world shaking and jittering um becomes very perceptible so what might be a reasonable tracking solution</transcript><transcript><audio_57>for looking at your hands or just tracking viewpoint from a scene but you're watching it on a screen maybe up to one centimeter of air is fine but we need to be sub millimeter level of accuracy it becomes very clear once you put on a virtual reality headset and you</transcript> get down the level of accuracy that we would like which i should point out the goal is sub millimeter accuracy why is the goal some millimeter accuracy well if you have very large deviations it's quite perceptible you know if i'm if i put on a virtual reality headset and i start seeing the world shaking and jittering um becomes very perceptible so what might be a reasonable tracking solution for looking at your hands or just tracking viewpoint from a scene but you're watching it on a screen maybe up to one centimeter of air is fine but we need to be sub millimeter level of accuracy it becomes very clear once you put on a virtual reality headset and you
