For the following questions, mark True or False:  1. Ultrasound haptics are developed based on the precise control of a series of speakers that send out precisely timed ultrasound pulses.[1] 2. Time differences between pulses are designed so that the ultrasound waves from the various speakers arrive at different places simultaneously.[2] 3. Ultrasound haptics create a pressure point that can be felt by human skin.[3] 4. The focal point where the ultrasound waves meet can be controlled in real time and changed from moment to moment based on hand positioning or other factors.[4] 5. A microphone can be used to track the hand. [5]

Please mark True or False for the items below: 1. Inertia Measurement Units are one method used to track objects moving in the real world.[1] 2. Camera based systems are exclusively used for stationary objects and cannot track moving objects. [2] 3. Lasers are not used for tracking moving objects in the real world. [3] 4. Mechanical linkages provide a way to track moving objects through physical connections. [4] 5. Electromagnetic trackers are one of the technologies used to track objects moving in the real world. [5]

Mark True or False regarding tracking systems. 1. Inertial Measurement Units merge accelerometers and gyroscopes, often alongside a magnetometer. [1] 2. For tracking in VR, we typically care about linear acceleration or angular velocity, not position and orientation. [2] 3. Integration converts measurements of velocity or acceleration in positions and orientations. [3] 4. Drift is typically corrected by additional sensors. [4] 5. Mechanical Linkage Systems use sensors at joints to detect angles, and compute a position. [5]
