1 Control Menus: Execution and Control in a Single Interactor Stuart Pook Eric Lecolinet Guy Vaysseix Emmanuel Barillot École Nationale Supérieure des Télécommunications ( ENST / INFRES ), France Infobiogen, France Généthon, France

2 The Problem  Choose and control continuous operations  Example: Acrobat Reader  three ways to zoom: dialog box, option menu, mouse button  three ways to pan: dialog box, scroll bar, mouse button  Various problems:  many ways and modes  multiple focus switches  non contextual  screen space  repeated uses

3 Control Menu  New type of pop-up menu  visually similar to a marking menu  Combines choice and control  single continuous reversible action  no focus switches  immediate feedback We propose a new type of pop-up menu that is circular and visually similar to marking menu. A control menu is shown here. As this menu is a pop-up it is contextual. The mouse click used to pop-up the menu indicates where the action chosen by the menu is to be applied. The gesture used to pop-up the menu continues so as to select an operation from the menu and to then control this operation.

4 Uses in Zoomable User Interfaces this short video shows the mouse movements used to select the zoom operation from the menu and to zoom the image. The mouse logo next to the cursor shows when the mouse button was pressed. I was not able to capture the change in cursor at the start and end of the zoom operation. this short video shows the mouse movements used to select the zoom operation from the menu and to zoom the image. The mouse logo next to the cursor shows when the mouse button was pressed. I was not able to capture the change in cursor at the start and end of the zoom operation.  Lots of mouse driven operations  One control menu sufficient for all  Each controlled by a single gesture  All operations unified

5 Control vs. Marking Menus  Control and marking menus:  novices see the menu  experts don’t  Control menu:  distance rather than the form of the gesture  (proportional) control bidirectional interactor  replaces menu and two scroll bars Both marking and control menus have novice and expert gestures. We saw the novice’s gesture on the video. The gesture of an expert is the same as that of a novice except without the third of a second pause that causes the menu to be shown. A user that knows the location of a menu item doesn’t have to wait to see menu. If she is unsure a short pause at the beginning of the operation will cause the menu to be drawn. Control menus differ from marking menus in that with a marking menu it is the form not the scale of the user’s gesture that is important. With a control menu it is the distance that is important. A control menu incorporates the control of an action into the gesture used to select it. This control is proportional to the user’s mouse movements and can be in two different directions. A control menu can thus replace up to two scroll bars for each menu item. Both marking and control menus have novice and expert gestures. We saw the novice’s gesture on the video.

6 Panning and expert use i3: The second (and last) video will show a control menu used to pan an application and the use of the control menu by someone who knows the location of the difference menu items. i3: The second (and last) video will show a control menu used to pan an application and the use of the control menu by someone who knows the location of the difference menu items.

7 Status and Future Directions  Zomit and HuGeMap  in Java (  browse biological database  Other applications  word processor We have used a control menu to control a Zoomable User Interface. The user interface part of this program is in Java and can be tested over the Web. This Zoomable User Interface is a browser for a biological database. We are currently working on adapting our control menu for use in different types of applications. Word processor are one example that we are developing.
