An Informal Study of Selection-Positioning Tasks (13 min. 17 sec.) University of Toronto 1982	A large part of my work has to do with compound rather than individual atomic tasks.  This is an early example, which compares a number of different approaches to articuluating selection/positioning tasks.  The study forshadows our later interest in marking menus, and grew out of our work on the SSSP (especially the score editing tools).  What is frightening  about this video is, on the one hand, how young I was, and on the other, how little my message has changed.  Sigh.

	"Etch" A Study in Marking-Based Interaction (4 min. 1 sec.) University of Toronto 1983	The overall complexity of marking based systems can be reduced if one can impose some underlying rules or structure on the dialogues.  This study illustrates one example of attempting to do so, showing how a basic vocabulary can apply to different types of data, such as text or graphics.

	Menulay  - A UIMS for Rapidly Sketching, Prototyping and Implementing User Interfaces (3 min. 51 sec.) University of Toronto 1983	Menulay was an early user interface management system (UIMS).  As the video shows, it was done at a time when calligraphic, rather than raster scan displays were common (although it did handle both).  As is shown, it enabled the user to rapidly create rich media interfaces.

	Issues & Techniques in Touch-Sensitive Tablet Input (9 min. 7 sec.) University of Toronto 1985	An overview of considerations and techniques in the use of touch tablets is presented.  This includes identifying a few key attributes of touch tablets that make them attractive, compared to mice and trackballs, for example, in certain situations.  Touch tablets of different form-factors are considered, including integrated into a PDA.  Likewise, there is a demonstration of how a single tablet can be partitioned into a (limited) number of virtual devices, and still be used eye-free.  The tape concludes with a brief introduction of the multi-touch tablet presented more fully in the next video, below.

	A Multi-Point Touch Sensitive Tablet (3 min. 8 sec.) University of Toronto 1985	I have always been interested in the potential of touch tablets.  What always seemed a shame is how few supported pressure, or any way of sensing the the degree of touch, or had the capability to sense more than one point of contact at a time.  This is a prototype tablet that did both..

	A Study in Two-Handed Input (4 min. 56 sec.) University of Toronto 1986	This is the first experimental work that I participated in.  This study was my first formal work in bimanual input, although two-handed input was something that I had done in practice from the start.  However, this paper established this as an important theme in my research career.

	Templates on Touch Tablets to Support Virtual Devices (1 min. 55 sec.) University of Toronto 1990	One of the main reasons that touch tablets interested me was that you didn't have any mechanical intermediary between your hand and the tablet.  Hence you could use multple hands and/or fingers, and carve up the space into multiple virtual devices, much like the window manager on a display. Ref: Brown, E., Buxton, W. & Murtagh, K. (1990). Windows on tablets as a means of achieving virtual input devices. In D. Diaper et al. (Eds), Human-Computer Interaction - INTERACT '90.

	Gedit (2 min. 5 sec.) University of Toronto 1991	This is a video showing some of the very early work on "marking menus."  This clip does not demonstrate everything in the paper, but gives the flavour of some of the relevant issues.

	MATE (3 min. 54 sec.) University of Toronto 1993	MATE was a prototype that investigated the design of a tool to support the life-cycle of a document after it had been written, but before completion, i.e., annotaion, correction, editing, etc.  It supported collaboration and was especially considering the use of pen-based interfaces.  It has perhaps even more relevance now than when it was originally done..

	Toolglass & Magic Lenses (10 min. 12 sec.) Xerox PARC 1993	Toolglass and Magig Lenses represent a new paradigm for two-handed input that is based on how we undertake bimanual asymetric tasks in the everyday world.  The technique exploits everyday skills, increases the power of expression, yet can also build on existing GUI designs, thereby not requiring a whole new design.

	The Chameleon: Spatially-Aware Palmtop Computers (5 min. 5 sec.) University of Toronto 1993	This video demonstrates an early prototype of a hand-held digital device where one navigates through the information displayed in a manner somewhat analogous to how one looks at the world through a camera's viewfinder: one pans left/right & up/down to change the firection of view, and moves in to get a close-up and out to get an overview. In order to avoid arm fatigue, or uncomfortable positions, or always moving images, a "clutch" button is included so that one can engage or disengage the navigation. Effectively, this enables one to reset the origin of the coordinate space. Ref: Fitzmaurice, George W. (1993). Situated information spaces and spatially aware palmtop computers.

	Graspable User Interface (3 min. 34 sec.) University of Toronto 1997	This video introduces the notion of what we call "graspable" user interfaces.  These have also been called "props based" or "tangible" UIs.  It is a style of UI in which key components are manifest in graspable physical props whose physical form relates to their function.  Ref: Fitzmaurice, G.W., Ishii, H. & Buxton, W.
