Comparing Gesture and Touch for Notification System Interactions

We explore some of the characteristics of multimodal input interaction spaces for notification systems within a multi-tasking environment like a command and control center using two promising interaction methods: gestures and touch based input through a laboratory experiment comparing both techniques. Results of our study suggest that gestures are better suited for multi-tasking situations because they are less interruptive than touch interaction to users' primary tasks and are subjectively preferred by users in certain situations.
