time-series graphs
I worked on the relaxed selection technique and the speed selection technique for the selection of regions in a graph. While selecting data from a time-series graph, the user can implicitly specify the level of similarity required to match a pattern on a point-by-point basis. Search queries can be defined with a single-gesture interaction.
menu systems
Menus are often used to support interaction and offer the execution of context-based operations. Usually, invoking a menu option finishes the preceding operation. In contrast, continuation menus allow seamless continuation of the original activity. Activating a menu and triggering an item can be integrated into an ongoing interaction process.
