Involving graphic designers in the large-scale development of user interfaces requires tools that provide more graphical flexibility and support efficient software processes. These requirements were analysed and used in the design of the TkZ-inc graphical library and the IntuiKit interface design environment. More flexibility is obtained through a wider(More)
Modernizing workstations for air traffic controllers is a challenge: designers must increase efficiency without affecting safety in any way. Air traffic control is a time-intensive and safety-critical activity, and thus interaction efficiency and low error rates are crucial. Classical interaction techniques have been used in prototype workstations, but the(More)
GRIGRI is a 2D gesture based HMI (Human Machine Interface) for a future air traffic controller work position. 2D gesture recognition is used to enter commands and values. To evaluate the usability and problems of such a HMI, we have experimented GRIGRI with controllers. We present results of recognition, input time and controller feelings. The experiment(More)
