Abstract

By using line movement, a user can easily divide a screen into multiple areas for screen sharing between several applications; further, the applications assume the display characteristics of the structure holding them. Many screen-sharing schemes force the user, by means of "pinning" the applications to the display screen, to guess at the coordinates required to properly divide the screen. A line movement screen model is presented which allows the user to lay out a screen arrangement which is independent of any applications which may be assigned to it and incorporates two significant features: 1. An intuitive user interface is created which, by moving one or more lines on the display, creates screen division without guesswork. 2.

Display Screen Division Using Line Movement Screen Carving Model

By using line movement, a user can easily divide a screen into multiple areas for screen sharing between several applications; further, the applications assume the display characteristics of the structure holding them. Many screen-sharing schemes force the user, by means of "pinning" the applications to the display screen, to guess at the coordinates required to properly divide the screen. A line movement screen model is presented which allows the user to lay out a screen arrangement which is independent of any applications which may be assigned to it and incorporates two significant features: 1. An intuitive user interface is created which, by moving one or more lines on the display, creates screen division without guesswork. 2. By focusing on drawing lines on the screen, the user-carved screen, regardless of whether tasks have been assigned to the areas carved out, can more easily be saved and restored. Applications assume the display characteristics of the structure holding them; size is not an attribute of a task, but rather of the screen itself. The process of moving lines is as follows: 1. The four exterior borders are drawn around the selected screen. This provides the user with all necessary options for creations of any rectangular screen geometry. These lines are virtual and used for line-generation purposes only. 2. According to our line-division algorithm, lines and line segments are offered (by highlighting, for example) to the user for movement. The user may ring through the set of lines offered until he/she finds the desired line. All eligible lines are offered, both exterior borders and interior segments. 3. Using cursor movement keys, the operator indicates the new position of the line that is currently selected. 4. The operator enters this position, and the new line is built on the screen. Adjustments to any application which is currently displayed on the screen are made. 5. Steps 2-4 may be repeated any number of times until the desired effect is achieved. 6. Upon completion of the screen design, move mode is exited and the exterior border lines are removed, giving these rows and columns back to any...
