Project: Bimanual In-Place Commands

Here’s another interesting loose end, this one from 2012, which describes a user interface known as “In-Place Commands” that Michel Pahud, myself, and Bill Buxton developed for a range of direct-touch form factors, including everything from tablets and tabletops all the way up to electronic whiteboards a la the modern Microsoft Surface Hub devices of 2015.

Microsoft is currently running a Request for Proposals for Surface Hub research, by the way, so check it out if that sort of thing is at all up your alley. If your proposal is selected you’ll get a spiffy new Surface Hub and $25,000 to go along with it.

We’ve never written up a formal paper on our In-Place Commands work, in part because there is still much to do and we intend to pursue it further when the time is right. But in the meantime the following post and video documenting the work may be of interest to aficionados of efficient interaction on such devices. This also relates closely to the Finger Shadow and Accordion Menu explored in our Pen +Touch work, documented here and here, which collectively form a class of such techniques.

While we wouldn’t claim that any one of these represent the ultimate approach to command and control for direct input, in sum they illustrate many of the underlying issues, the rich set of capabilities we strive to support, and possible directions for future embellishments as well.

In-Place Commands Screen Shot

The user can call up commands in-place, directly where he is working, by touching both fingers down and fanning out the available tool palettes. Many of the functions thus revealed act as click-through tools, where the user may simultaneously select and apply the selected tool — as the user is about to do for the line-drawing tool in the image above.
