Abstract: According to one aspect, it becomes possible to easily modify a 3D object which is displayed in a virtual reality space. A method is performed by a computer configured to be communicable with a position detection device that includes a drawing surface and that, in operation, detects a position of an electronic pen on the drawing surface. The method includes rendering, in a virtual reality space, a first object that is a 3D object, rendering, near the first object, a display surface that is a 3D object, rendering, on the display surface, a 3D line that is a 3D object generated based on the position of the electronic pen on the drawing surface, wherein the position of the electronic pen is detected by the position detection device, and outputting the first object, the display surface, and the 3D line, which are the 3D objects, to a display.

Abstract: A computing device (e.g., a host computer in communication with a tablet input device) receives pen data corresponding to first and second positions of a pen device. The computing device compares the first and second positions to obtain an angle and an offset distance between the positions. The computing device selects a scrolling direction (either vertical or horizontal) based on the angle, with the selection being biased towards vertical scrolling. The computing device determines a number of scrolling events based on the offset distance, which may include comparing the offset distance with a preselected minimum distance. The computing device sends the scrolling events to an application executing on the computing device. The scrolling events cause the application to render scrolling in the selected scrolling direction. The pen data may include an indication of pen-down status and/or pen button activation to help determine whether to activate or terminate scrolling.
