In recent works, we have developed a text input method based on analogy with capital Latin characters and on the decomposition of characters into basic shapes. It has been designed to be universal and to allow for typing text with only one keystroke per character. In this paper we present a new implementation of this method for users with motor impairments.(More)
Suppose a user is interacting with other persons around a digital tabletop or in front of a digital wall. A user wants to launch a new graphical component or an application in the part of the screen next to him. Traditional methods such as popup menus allow him to first open the application and afterwards let him move, resize and orient the component(More)
Previously, we developed a text input method called Glyph which we improved later to make it possible to enter text on mobile devices with two keystrokes per character, then with one simple gesture per character using seven keys. In this paper, we announce a new method called "UniGlyph". It allows typing text with one keystroke per character using only four(More)
In this paper, we describe the Sketched Menu, a menu technique for launching Graphical User Interface (GUI) objects in a tabletop interface. The Sketched Menu enables the user to define interactively the shape, size, orientation, and location of a new GUI object before it is launched. These parameters are specified implicitly by the user via a shape(More)
Glyph is a new version of the text entry method called Glyph. Glyph 2 is designed in order to make easier, more flexible and more rapid the text input. The main difference is that Glyph 2 uses only two keystrokes per character. As Glyph, the character input is based on a decomposition in basic shapes, according to a principle of analogy with Roman(More)
In this paper we describe a new mobile text input method called "HandiGlyph" for severe disabled people based on the universal UniGlyph character set. It uses the same principles as UniGlyph in addition to some well-known techniques used in Augmentative and Alternative Communication (AAC). The new solution was evaluated with a disabled user suffering of the(More)
This paper describes two tabletop interaction techniques for collocated collaborative work. These techniques aim to improve the transitions between individual and collective tasks to improve the collaborative interaction. The first technique is based on common document browsing techniques with the decomposition of the browser into independent components to(More)
