Application No. 09/028,480
Here, Tannenbaum discloses a "method of operating a computer with an
integrated operating environment and operating system capable of running a plurality of
application programs simultaneously. . . ." Col. 4, ll. 36-39. As shown in Figure 9 of the
reference, "[a] graphical user interface 300 is presented on the system display equipped
with a touch sensor over its viewing surface. Three overlapping
windows 302, 304, 306 are displayed which are owned by applications I, J and K
respectively." Col. 18, ll. 25-29.
The reference's "method . . . includes the step of determining which one of the
application programs owns a first window in which a key feature of a gesture was made
by a pointing device." Col. 4, ll. 44-48. Specifically, Tannenbaum "designat[es] one key
point within a gesture as a 'hot spot'”. The window or icon in which the hot spot occurs
is determined to be the focus of the user. . . ." Col. 18, ll. 45-47. "Thus, the user is not
restricted to drawing the gesture completely within the window of the target application."
Id. at ll. 58-59.
The reference's "first gesture is a pigtail," id. at l. 68, which it shows in Figure 10.
"Typically, the hot spot is designated to be at a prominent and intuitive point within the
gesture." Id. at ll. 64-65. As shown in Figure 10, the pigtail's "hot spot [is] at one end of
the shape," col. 19, l. 1, i.e., either the pen-down end or the pen-up end of the shape.
When the hot spot is at the pen-down end of the pigtail gesture, we find that
Tannenbaum detects where its pointing device is put down on its display.
