Publication number: 20200126280Abstract: A position data acquiring unit 200 acquires position data indicating a position of a real object. A delay deriving unit 206 derives delay time in an information processing system 1. A motion predicting unit 300 predicts a movement of the object, and identifies an object position at a future time on the basis of the position data acquired by the position data acquiring unit 200, the predetermined length of time being equal to or longer than the delay time. An image generating unit 302 generates a prediction image in which the object position at the future time is reflected. A display image providing unit 204 acquires the generated prediction image, and provides the prediction image to an HMD.Type: ApplicationFiled: June 7, 2017Publication date: April 23, 2020Inventors: Tatsuki AMIMOTO, Akira NISHIYAMA

Publication number: 20180080939Abstract: The present invention provides a novel cancer marker for testing a morbidity risk of a cancer. The cancer marker according to the present invention is a prorenin receptor. A test method for testing a morbidity risk of a cancer according to the present invention includes measuring a prorenin receptor expression in a biological specimen obtained from a subject and further includes, for example, a step of comparing a prorenin receptor expression level in the biological specimen obtained from the subject with a reference value to test the morbidity risk of the cancer in the subject. The reference value is a prorenin receptor expression level in a biological specimen obtained from a healthy subject or a cancer patient. When the expression level in the subject is higher than that in the healthy subject or identical to or higher than that in the cancer patient, it can be evaluated that the subject has the mobility risk of the cancer.Type: ApplicationFiled: November 22, 2017Publication date: March 22, 2018Inventors: Akira NISHIYAMA, Fumiaki SUZUKI
