tm(l) tm(l) NAME tm - "typemon" monitor keyboard and mouse activity and suggest rest breaks. SYNOPSIS tm [ -bprtmvo ] [ keyboard_dev_path ] [ mouse_dev_path ] DESCRIPTION This X11-based program attempts to reduce repetitive stress injury (RSI) by monitoring mouse and keyboard activity to suggest periodic rest breaks. If the consecutive time of typing or mousing exceeds the user-defined limits, then a warning window pops up advising the user to take a rest break. The window remains until there has been no typing or mousing for the user-defined rest time. A log file ~/.typelog keeps track of the total cumulative typing and mousing times for each day. This data can be plotted in histogram form using the script typehisto. The main status window contains two bargraphs to allow the user to plan his rest breaks. The upper bargraph shows the percentage of time spent in the current working period. The lower bargraph shows the current amount of pause time. When the pause time bar graph reaches 100% of the rest time, the upper bargraph is zeroed. This feature allows the user to plan "pre-emptive" rest breaks to coincide with natural pauses in work activity. A new feature in this version of tm is a "stop" button in the upper right corner of the tm status window. This button allows tm to be temporarily stopped to avoid annoying a visitor. When tm is stopped, the normally blue bar-graph is displayed as red. An option menu allows the user to reset the activity timer, display the status of all command line options, and show the current version number. -r rest_time This specifies the resting period, in seconds, that is required to clear the warning window once the maximum typing or mousing times have been exceeded. -t maximum_typing_time This is the maximum consecutive typing time allowed (in seconds). If this parameter is not specified, but the maximum_mousing_time is, then the maximum_typing_time will be set equal to the maximum_mousing_time. If neither parameter is set, then default values will be used for both. The typing timer increments whenever one is typing. If typing stops for more than pause_time, the timer stops counting. If typing does not resume in rest_time the typing timer is reset to zero. Whenever the timer reaches maximum_typing_time, the warning window is activated. The warning window remains active until there has been no typing or mousing activity for rest_time. Once inactivity has remained for rest_time, the window is cleared and the typing and mousing - 1 - Formatted: December 5, 1995 tm(l) tm(l) timers are reset to zero. -m maximum_mousing_time This is the maximum consecutive mousing time allowed (in seconds). If this parameter is not specified, but the maximum_typing_time is, then the maximum_mousing_time will be set equal to the maximum_typing_time. If neither parameter is set, then default values will be used for both. The mousing timer increments whenever one is mousing. If mousing stops for more than pause_time, the timer stops counting. If mousing does not resume in rest_time the mousing timer is reset to zero. Whenever the timer reaches maximum_mousing_time, the warning window is activated. The warning window remains active until there has been no mousing or typing activity for rest_time. Once inactivity has remained for rest_time, the window is cleared and the typing and mousing timers are reset to zero. If both typing and mousing are occurring simultaneously, the internal timers are incremented by an amount equal to the weighted averages of maximum_typing_time and maximum_mousing_time. The warning will then be issued at an interval of time that falls somewhere between maximum_typing_time and maximum_mousing_time. -p pause_time This time (in seconds) determines how long of a pause will stop the mouse and keyboard activity timers from running. -b This option runs tm in the background without generating the normal status window. -v verbose logfile. This option writes updated information to the logfile each time the keyboard or mouse change from active to passive states. This option will cause the logfile to grow very quickly and is normally only used for debugging. -o obnoxiousness_level This option specifies how obnoxiously the program will try to persuade you to rest. A default setting of "0" will pop up the "Take a break" window in the middle of the screen only once and will silently truncate the "Continue Resting" bar graph for rest violations. Settings of "1" and above will not destroy the "warn" window when the "reset timer" button is selected from the "Options" menu, making it harder to "cheat" on the rest period. A setting of "1" issues an audible beep everytime you violate your rest period. A setting of "2" will both beep and recenter the window for every violation. Level "3" is the same as level "2", but also grabs the keyboard and mouse focus, essentially taking over the user interface until the timer expires. Level "3" is guaranteed to stop the most flagrant violator! - 2 - Formatted: December 5, 1995 tm(l) tm(l) keyboard_dev_path, mouse_dev_path As currently written, the program assumes it is running on an HP-UX system, and it scans the /dev/hil[1-7] files to find out which devices are busy (ie., already opened by X11). The last busy device is assumed to belong to the mouse, and the next lower busy device is assumed to be the keyboard. These arguments can be used to override the program's choice of device files. They should only be needed for unusual system configurations. A good way to figure out which device files to use is to run "ls -lrtu /dev/hil*". This gives a verbose listing of the /dev files, reverse sorted by their last access time. Usually the last two entries in the listing will correspond to your keyboard and mouse. X11 hackers may wish to modify the routine get_dev_files in the tm script to autoconfigure properly for non HP-UX systems. EXAMPLES To specify a maximum 10-minute typing time and 15-minute mousing time, with a 2-minute rest time and a 10-second pause threshold: "tm -t 600 -m 900 -r 120 -p 10" SEE ALSO A good reference book on this subject is Emil Pascarelli and Deborah Quilter, "Repetitive Strain Injury, A Computer User's Guide", 1994, John Wiley and Sons, ISBN 0-471-59533-0. FILES The default logfile is ~/.typelog. The executable is /usr/local/bin/tm. Tm is built with the tcl/tk window shell package by John Ousterhout (See usenet group comp.lang.tcl for details, or check out "http://web.cs.ualberta.ca/~wade/Auto/Tcl.html" for the latest release). As distributed, tm is written for the tcl3.6/tk4.0 wish interpreter. AUTHORS Rick Walker (walker@opus.hpl.hp.com), and Tom Knotts (knotts@opus.hpl.hp.com). This program was inspired by, and is similar to the script 'typewatch' by Richard Donkin (richardd@hoskyns.co.uk). It was completely re-written in C to enhance performance and monitor of mouse activity, and later re- written in tcl/tk to improve the user interface. BUGS Use this program at your own risk. No liability is assumed for the results of using this program. The proper values of working and resting times should be selected by you according to the advice of your doctor. - 3 - Formatted: December 5, 1995
