Abstract

According to an embodiment, an information display system includes a displacement measurement unit, a display unit, and a controller. The displacement measurement unit measures displacement of a measurement part. The display unit displays a time axis of signal detection. The controller controls the displacement measurement unit and the display unit. When a signal that is output from the displacement measurement unit meets a given condition, the controller determines that displacement of the measurement part is detected and displays detection information representing that the displacement is detected in any one of a time position and a time area on the display unit in which the displacement is detected.

First claim

a controller configured to control the optical tracking device and the display unit,
the controller is further configured to determine that displacement of the measurement part is detected based on the output signal of the optical tracking device, the determining that displacement of the measurement part is detected including measuring a distance of displacement of the current position of the measurement part of the patient from an original position of the measurement part, and determining whether the distance of displacement meets a desired threshold distance, and
display the collected biological signals on the time axis of the display unit in synchronization with detection information representing that the displacement is detected in any one of a time position and a time area on the display unit in which the displacement is detected, and display displacement information in association with the detection information and the collected biological signals in the any one of the time position and the time area in which the displacement is detected.

2. The information display system according to claim 1 , wherein
the controller is further configured to store in memory of the information display system the displacement information in association with the detection information.

3. The information display system according to claim 2 , wherein
