Abstract: A virtual reality (VR) sickness assessment method according to an embodiment includes receiving virtual reality content, and quantitatively evaluating virtual reality sickness for the received virtual reality content using a neural network based on a pre-trained neural mismatch model. The evaluating of the virtual reality sickness may include predicting an expected visual signal for an input visual signal of the virtual reality content based on the neural mismatch model, extracting a neural mismatch feature between the predicted expected visual signal based on the neural mismatch model and an input visual signal for a corresponding frame of the virtual reality content corresponding to the expected visual signal, and evaluating a level of the virtual reality sickness based on the neural mismatch model and the extracted neural mismatch feature.

Abstract: Disclosed are a flexible vibration cushion and a method of controlling the same. The flexible vibration cushion may include a cover member, a first soft filler material filled in the cover member; and a vibration generation device including components made of a soft material and disposed in the soft filler. The vibration generation device is configured to generate vibration as an electrostatic force is repeatedly generated and released. The vibration generation device may be applied in a vehicle part, e.g., headrest, thereby minimizing the foreign body sensation acting on the user’s skin while delivering soft and various senses of vibrations to the user.
