   "title": "Studies and guidelines for two concurrent stroke gestures",
   "url": "https://hal.science/hal-04031673",
   "abstract": "This paper investigates thumb-index interaction on touch input devices, and more precisely the potential of two concurrent stroke gestures, i.e. gestures in which two fingers of the same hand concurrently draw one stroke each. We present two fundamental studies, one using such gestures for two-dimensional control, by precisely drawing figures, and the other for command activation, by roughly sketching figures. Results give a first analysis of user performance on 35 gestures with a varying complexity based on numbers of turns and symmetries. All 35 gestures, were grouped into six families. From these results we classify these families and propose new guidelines for designing future mobile interfaces. For instance, favoring anchored gestures (forefinger drawing while the thumb remains still on the surface) to increase input bandwidth when forefinger precision is required.",

   "title": "Exploring 3D Objects with Non-Linear Perspectives in Real-Time, a First User Study",
   "url": "https://hal.archives-ouvertes.fr/hal-02959371",
   "abstract": "Non-linear perspectives have the potential to improve 3D scene perception by increasing the information bandwidth of 3D contents. As with the example of the Mercator projection of earth, they can reduce occlusions by showing more of the shape of an object than classical perspectives. However, an ill-advised construction of such \"usually static\" perspectives could make the original shape difficult to understand, drastically reducing the scene comprehension. Yet, despite of their potential, these perspectives are rarely used. In this paper we aim at making non-linear perspectives more widely usable on mobile devices. We propose to solve the understanding issue by allowing the user to control the transition between linear and non-linear perspectives in real-time with bending gestures. Using this approach, we present the first user study that investigates real-time manipulation of non-linear perspectives in an exploration task. Results show significant benefits of the approach, and give insights on the best bending gestures and configurations.",

Many research projects have pushed bendable surfaces from prototypes to commercially viable devices. In the meantime, expandable devices have become a topic of interest letting one foresee that such devices are on the horizon. With BEXHI, we provide a structure to explore the combined capabilities of these devices. The structure consists of multiple interweaved units allowing non-porous expandable surfaces to bend. Through an instanciation, we illustrate and discuss that the BEXHI structure allows for the exploration of the combination of both bend and expansion interaction spaces.",

   "title": "Pointing at 3D Wiggle Displays",
   "abstract": "This paper presents two new pointing techniques for wiggle 3D displays, which present the 2D projection of 3D content with automatic (rotatory) motion parallax. Standard pointing at targets in wiggle 3D displays is challenging as the content is constantly in motion. The two pointing techniques presented here take advantage of the cursor’ s current position or the user’ s gaze direction for collocating the wiggle rotation center and potential targets. We evaluate the performance of the pointing techniques with a novel methodology that integrates 3D distractors into the ISO-9241-9 standard task. The experimental results indicate that the new techniques are significantly more efficient than standard pointing techniques in wiggle 3D displays. Given that we observed no performance variation for different targets, our new techniques seem to negate any interaction performance penalties of wiggle 3D displays.",

EXHI-bit surfaces can be combined to create 2D and 3D multi-surface objects. In this paper, we demonstrate the versatility and generality of EXHI-bit with user-deformed and self-actuated 1D, 2D, and 3D prototypes employed in an architectural urban planning scenario.

   "abstract": "In this paper we describe a new orbiting algorithm, called SHOCam, which enables simple, safe and visually attractive control of a camera moving around 3D objects. Compared with existing methods, SHOCam provides a more consistent mapping between the user’s interaction and the path of the camera by substantially reducing variability in both camera motion and look direction. Also, we present a new orbiting method that prevents the camera from penetrating object(s), making the visual feedback – and with it the user experience – more pleasing and also less error prone. Finally, we present new solutions for orbiting around multiple objects and multi-scale environments.",

It allows pointing in dense 3D environments, and on targets moving with high velocity. Moreover, Hook minimizes the impact of its visual feedback for maintaining user’s interaction comfort. Two adaptations of Hook for 2 dof (degrees-of-freedom) and 3 dof interaction for 3D environments have been evaluated. Results clearly show that Hook outperforms the existing methods in pointing time and error rates, for fast and slow targets, in the two configurations. All the participants confirmed the expected feeling with regards to ease of use.",

   "title": "Benchmarking Pointing Techniques with Distractors: Adding a Density Factor to Fitts' Pointing Paradigm",
   "url": "http://iihm.imag.fr/blanch/projects/distractors/",
   "abstract": "Fitts' pointing paradigm is widely used to conduct controlled experiments and to evaluate new interaction techniques enhancing target acquisition. Many of them change the behavior of the cursor according to various inputs, most notably the positions of potential targets.\r\n\r\nWe propose to extend Fitts' paradigm in order to challenge those techniques with distractors (i.e., potential targets which are not the goal of the user) in a controlled manner. To reduce variability, we add a single new factor to the paradigm, the distractor density. We specify a distractors distribution, fully determined by this factor together with those of Fitts' task, aimed at reducing bias toward a specific technique.\r\n\r\nWe also propose a preliminary extension of Fitts' law to take account of the sensitivity to the density of distractors as well as of the task difficulty. In an experiment, we compare five existing pointing techniques, and show that this extended protocol enables contrasted comparisons between them.\r\n",

   "title": "AirMouse: Finger Gesture for 2D and 3D Interaction",
   "abstract": "This paper presents AirMouse, a new interaction technique based on finger gestures above the laptop’s keyboard. At a reasonably low cost, the technique can replace the traditional methods for pointing in two or three dimensions. Moreover, the device-switching time is reduced and no additional surface than the one for the laptop is needed. In a 2D pointing evaluation, a vision-based implementation of the technique is compared with commonly used devices. The same implementation is also compared with the two most commonly used 3D pointing devices. The two user experiments show the benefits of the polyvalent technique: it is easy to learn, intuitive and efficient by providing good performance. In particular, our conducted experiment shows that performance with AirMouse is promising in comparison with a touchpad and with dedicated 3D pointing devices. It shows that AirMouse offers better performance as compared to FlowMouse, a previous solution using fingers above the keyboard.",

   "title": "Rake Cursor: Improving Pointing Performance with Concurrent Input Channels",
   "url": "http://iihm.imag.fr/blanch/projects/rake-cursor/",
   "abstract": "We investigate the use of two concurrent input channels to perform a pointing task. The first channel is the traditional mouse input device whereas the second one is the gaze position. The rake cursor interaction technique combines a grid of cursors controlled by the mouse and the selection of the active cursor by the gaze.\r\n\r\nA controlled experiment shows that rake cursor pointing drastically outperforms mouse-only pointing and also significantly outperforms the state of the art of pointing techniques mixing gaze and mouse input. A theory explaining the improvement is proposed: the global difficulty of a task is split between those two channels, and the sub-tasks could partly be performed concurrently. ",
