Quinn, Philip, Cockburn, Andy, Casiez, Géry, Roussel, Nicolas and Gutwin, Carl (2012): Exposing and understanding scrolling transfer functions. In: Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 341-350.

Scrolling is controlled through many forms of input devices, such as mouse wheels, trackpad gestures, arrow keys, and joysticks. Performance with these devices can be adjusted by introducing variable transfer functions to alter the range of expressible speed, precision, and sensitivity. However, existing transfer functions are typically "black boxes" bundled into proprietary operating systems and drivers. This presents three problems for researchers: (1) a lack of knowledge about the current state of the field; (2) a difficulty in replicating research that uses scrolling devices; and (3) a potential experimental confound when evaluating scrolling devices and techniques. These three problems are caused by gaps in researchers' knowledge about what device and movement factors are important for scrolling transfer functions, and about how existing devices and drivers use these factors. We fill these knowledge gaps with a framework of transfer function factors for scrolling, and a method for analysing proprietary transfer functions -- demonstrating how state of the art commercial devices accommodate some of the human control phenomena observed in prior studies.

We argue that the current practice of using integer positions for pointing events artificially constrains human precision capabilities. The high sensitivity of current input devices can be harnessed to enable precise direct manipulation ""in between"" pixels, called subpixel interaction. We provide detailed analysis of subpixel theory and implementation, including the critical component of revised control-display gain transfer functions. A prototype implementation is described with several illustrative examples. Guidelines for subpixel domain applicability are provided and an overview of required changes to operating systems and graphical user interface frameworks are discussed.

We present Surfpad, a pointing facilitation technique that does not decrease target distance or increase target width in either control or display space. This new technique operates instead in the tactile domain by taking advantage of the ability to alter a touchpad's coefficient of friction by means of a squeeze film effect. We report on three experiments comparing Surfpad to the Semantic Pointing technique and constant control-display gain with and without distractor targets. Our results clearly show the limits of traditional target-aware control-display gain adaptation in the latter case, and the benefits of our tactile approach in both cases. Surfpad leads to a performance improvement close to 9% compared to unassisted pointing at small targets with no distractor. It is also robust to high distractor densities, keeping an average performance improvement of nearly 10% while Semantic Pointing can

Transfer functions are the only pointing facilitation technique actually used in modern graphical interfaces involving the indirect control of an on-screen cursor. But despite their general use, very little is known about them. We present EchoMouse, a device we created to characterize the transfer functions of any system, and libpointing, a toolkit that we developed to replicate and compare the ones used by Windows, OS X and Xorg. We describe these functions and report on an experiment that compared the default one of the three systems. Our results show that these default functions improve performance up to 24% compared to a unitless constant CD gain. We also found significant differences between them, with the one from OS X improving performance for small target widths but reducing its performance up to 9% for larger ones compared to Windows and Xorg. These results notably suggest replacing the constant CD gain function commonly used by HCI researchers by the default function of the considered systems.

We present the STIMTAC, a touchpad device that supports friction reduction. Contrary to traditional vibrotactile approaches, the STIMTAC provides information passively, acting as a texture display. It does not transfer energy to the user but modifies how energy is dissipated within the contact area by a user-initiated friction process. We report on the iterative process that led to the current hardware design and briefly describe the software framework that we are developing to illustrate its potential.

Chapuis, Olivier and Roussel, Nicolas (2010): UIMarks: quick graphical interaction with specific targets. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 173-182.

This paper reports on the design and evaluation of UIMarks, a system that lets users specify on-screen targets and associated actions by means of a graphical marking language. UIMarks supplements traditional pointing by providing an alternative mode in which users can quickly activate these marks. Associated actions can range from basic pointing facilitation to complex sequences possibly involving user interaction: one can leave a mark on a palette to make it more reachable, but the mark can also be configured to wait for a click and then automatically move the pointer back to its original location, for example. The system has been implemented on two different platforms, Metisse and OS X. We compared it to traditional pointing on a set of elementary and composite tasks in an abstract setting. Although pure pointing was not improved, the programmable automation supported by the system proved very effective.

Copy and move operations have long been supported by interactive desktops through various means. But the growing number of on-screen objects makes these means harder to use. In this note, we present new tools and techniques to enhance the existing ones: a selection, copy and drag history manager; two techniques to expose the user's desk and leaf through stacks of overlapping windows; and a technique that integrates the previous two with conventional drag-and-drop.

Chapuis, Olivier and Roussel, Nicolas (2007): Copy-and-paste between overlapping windows. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 201-210.

Copy-and-paste, one of the fundamental operations of modern userinterfaces, can be performed through various means (e.g. using the keyboard, mouse-based direct manipulation or menus). When users copy-and-paste between two different windows, the process is complicated by window management tasks. In this paper, we propose two new window management techniques to facilitate these tasks in the particular case of partially overlapping windows. We describe an experiment comparing four commonly-used copy-and-paste techniques under four window management conditions -- non-overlapping windows, partially overlapping windows, and partially overlapping ones with one of our two window management techniques. Results show that our new window management techniques significantly reduce task completion time for all copy-and-paste techniques. They also show that X Window copy-and-paste is faster than the other three techniques under all four window management conditions.

PageLinker is a browser extension that allows to contextualise navigation by linking web pages together and to navigate through a network of related web pages without prior planning. The design is based on extensive interviews with biologists, which highlighted their difficulties finding previously visited web pages. They found current browser tools inadequate, resulting in poorly organised bookmarks and rarely used history lists. In a four-week controlled field experiment, PageLinker significantly reduced time, page loads and mouse clicks. By presenting links in context, PageLinker facilitates web page revisitation, is less prone to bookmark overload and is highly robust to change.

User interfaces are becoming more and more complex. Adaptable and adaptive interfaces have been proposed to address this issue and previous studies have shown that users prefer interfaces that they can adapt to self-adjusting ones. However, most existing systems provide users with little support for adapting their interfaces. Interface customization techniques are still very primitive and usually constricted to particular applications. In this paper, we present User Interface Facades, a system that provides users with simple ways to adapt, reconfigure, and re-combine existing graphical interfaces, through the use of direct manipulation techniques. The paper describes the user's view of the system, provides some technical details, and presents several examples to illustrate its potential.

Twenty years after the general adoption of overlapping windows and the desktop metaphor, modern window systems differ mainly in minor details such as window decorations or mouse and keyboard bindings. While a number of innovative window management techniques have been proposed, few of them have been evaluated and fewer have made their way into real systems. We believe that one reason for this is that most of the proposed techniques have been designed using a low fidelity approach and were never made properly available. In this paper, we present Metisse, a fully functional window system specifically created to facilitate the design, the implementation and the evaluation of innovative window management techniques. We describe the architecture of the system, some of its implementation details and present several examples that illustrate its potential.

The quantity and diversity of digital information we produce, receive and download on a daily basis is now incompatible with the available tools for managing it. In this paper, we present a new approach to familiar data management that aims at taking advantage of the episodic memory of the user. We describe some of our ongoing work that aims at providing interactive systems with a long-term memory that would allow users to easily retrieve a particular data or context.

videoProbe is a device that takes pictures of everyday family life and shares them among multiple households. By providing family members with a new means of lightweight and informal communication, videoProbe allows unusual picture sharing and is likely to modify interactions within families. From a research perspective, videoProbe is an instance of a new class of device built to inspire ideas for the design of new communication technologies and to gather data about life in family.

Physical proximity between people is a language for non-verbal communication that we all employ everyday, although we are barely aware of it. Yet, existing systems for video-mediated communication fail to fully take it into account. In this paper, we present MirrorSpace, a new video communication system that uses proximity as an interface to provide smooth transitions from general visual awareness to very close and intimate forms of communication.
