To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

Moscovich, Tomer, Chevalier, Fanny, Henry, Nathalie, Pietriga, Emmanuel and Fekete, Jean-Daniel (2009): Topology-aware navigation in large networks. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2319-2328.
Applications supporting navigation in large networks are used every days by millions of people. They include road map navigators, flight route visualization systems, and network visualization systems using node-link diagrams. These applications currently provide generic interaction methods for navigation: pan-and-zoom and sometimes bird's eye views. This article explores the idea of exploiting the connection information provided by the network to help navigate these large spaces. We visually augment two traditional navigation methods, and develop two special-purpose techniques. The first new technique, called "Link Sliding", provides guided panning when continuously dragging along a visible link. The second technique, called "Bring&Go", brings adjacent nodes nearby when pointing to a node. We compare the performance of these techniques in both an adjacency exploration task and a node revisiting task. This comparison illustrates the various advantages of content-aware network navigation techniques. A significant speed advantage is found for the Bring&Go technique over other methods.

Chu, Gerry, Moscovich, Tomer and Balakrishnan, Ravin (2009): Haptic conviction widgets. In: Proceedings of the 2009 Conference on Graphics Interface 2009. pp. 207-210.
We introduce a haptic mousewheel as a platform for design exploration of haptic conviction widgets. Conviction is how strongly one wants to do something, or how strongly one desires a parameter to be as it is. Using the haptic mousewheel, the widgets allow users to communicate conviction using force, where greater conviction requires greater force. These widgets include buttons that take varying amounts of force to click, a trash can that requires overcoming force to delete files, an instant message client that requires more force to communicate a stronger emotion, and widgets that allow parameters to be locked using force.

Moscovich, Tomer (2009): Contact area interaction with sliding widgets. In: Proceedings of the ACM Symposium on User Interface Software and Technology 2009. pp. 13-22.
We show how to design touchscreen widgets that respond to a finger's contact area. In standard touchscreen systems a finger often appears to touch several screen objects, but the system responds as though only a single pixel is touched. In contact area interaction all objects under the finger respond to the touch. Users activate control widgets by sliding a movable element, as though flipping a switch. These Sliding Widgets resolve selection ambiguity and provide designers with a rich vocabulary of self-disclosing interaction mechanism. We showcase the design of several types of Sliding Widgets, and report study results showing that the simplest of these widgets, the Sliding Button, performs on-par with medium-sized pushbuttons and offers greater accuracy for small-sized buttons.

Moscovich, Tomer and Hughes, John F. (2008): Indirect mappings of multi-touch input using one and two hands. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1275-1284.
Touchpad and touchscreen interaction using multiple fingers is emerging as a valuable form of high-degree-of-freedom input. While bimanual interaction has been extensively studied, touchpad interaction using multiple fingers of the same hand is not yet well understood. We describe two experiments on user perception and control of multi-touch interaction using one and two hands. The first experiment addresses how to maintain perceptual-motor compatibility in multi-touch interaction, while the second measures the separability of control of degrees-of-freedom in the hands and fingers. Results indicate that two-touch interaction using two hands is compatible with control of two points, while twotouch interaction using one hand is compatible with control of a position, orientation, and hand-span. A slight advantage is found for two hands in separating the control of two positions.

Moscovich, Tomer and Hughes, John F. (2006): Multi-finger cursor techniques. In: Proceedings of the 2006 Conference on Graphics Interface 2006. pp. 1-7.
The mouse cursor acts as a digital proxy for a finger on graphical displays. Our hands, however, have ten fingers and many degrees of freedom that we use to interact with the world. We posit that by creating graphical cursors that reflect more of the hand's physical properties, we can allow for richer and more fluid interaction. We demonstrate this idea with three new cursors that are controlled by the user's fingers using a multi-point touchpad. The first two techniques allow for simultaneous control of several properties of graphical objects, while the third technique makes several enhancements to object selection.

Moscovich, Tomer and Hughes, John F. (2004): Navigating documents with the virtual scroll ring. In: Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004. pp. 57-60.
We present a technique for scrolling through documents that is simple to implement and requires no special hardware. This is accomplished by simulating a hardware scroll ring -- a device that maps circular finger motion into vertical scrolling. The technique performs at least as well as a mouse wheel for medium and long distances, and is preferred by users. It can be particularly useful in portable devices where screen-space and space for peripherals is at a premium.
