[net.cog-eng] Pop-Up Menu Data

davidst@tekgvs.UUCP (David Stubbs) (03/30/85)

Greetings!

Here's some pop-up menu results I've reduced from data captured on my
Tektronix Magnolia running 3-buttoned Smalltalk.  Smalltalk menus pop up
showing the previous choice selected for the window or the last item
highlighted before moving out of the menu (eg, when it turns out to be the
wrong menu, or the situation is discovered to be inappropriate).

The times do not account for all the system overhead of displaying,
data logging, and removing the menus. The clock resolution is 1/60th
second.  The relative average times and percentage of occurance may be
useful, however.

			  Average
	Menu Choice	  Time in			% of total
	Result		  Seconds	Occurances	occurances
	--------------- --------------- --------------- -----------
	Same selection
	as previous:	   0.967	  256	   	35.3

	Different
	selection:	   1.619	  417	   	57.4

	Wrong menu
	discovered:	   2.447	   53	   	 7.3

	Wrong menu to
	next menu
	selection:	  23.590

700+ lines of raw data is your's to fool with.  Its form is:

	 Number of  Menu item   Millisecond   Menu item  Millisecond
	 menu       highlighted clock at      selected   clock at
	 choices    on pop up   pop up                   selection
	___________ ___________ ___________  ___________ ___________

	     8           7        7065467         7        7066150
	    10           8        7107317         6        7108850


Simply ask!
