Which of the following statements about simulator sickness are TRUE? 1. Simulator sickness is caused only by issues with a user’s physical environment, such as poor ventilation or lighting. [1] 2. The most common type of sensory conflict in VR is between the visual and proprioceptive systems.[2] 3. Vomiting is the most frequent and expected symptom of simulator sickness.[3] 4. The SSQ (Simulator Sickness Questionnaire) is the most commonly used method to measure simulator sickness.[4] 5. The rest-frame hypothesis suggests that motion sickness stems from conflicting interpretations of what is stationary.[5]

For the following questions, mark True or False:  1. The Smelly VR Headset uses both hardware and software to produce different scents for the user.[1] 2. Immersive Winds VR uses a TP-Link smart plug and a house fan to simulate wind in Skyrim VR.[2] 3. Virtual food technology uses changes in temperature to mimic the sensation of sweetness on the tongue.[3] 4. OVR Technology’s Architecture of Scent platform operates using a wired connection and does not have a replaceable scent cartridge.[4] 5. Many interesting devices that produce sensations beyond vision, audio, and haptics are being developed, with many more expected in the future.[5]

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]
