....cognitive requirements that dominate the physical design of the instrument. We should therefore approach the design of the physical Man Instrument interface as a cognitive ergonomical problem. In the four cognitive ergonomical criteria for assessing the usability of systems defined by Shackel [20], functionality is described by means of the concept task: 1) Learnability: the amount of learning necessary to achieve tasks; 2) Ease of Use: the efficiency and effectiveness with which one can achieve these tasks; 3) Flexibility: the extent to which a system can adapt to new task and ....

....instruments into reach of the skilled musician. Introduction A key aspect in the ergonomics of computer music instrument design is that musical instruments are intended for skilled performance with limited functionality (i.e. one does not need to be able to edit text with it) According to [Shackel, 1990], the usability of systems can be measured using four criteria: Learnability: the amount of learning necessary to achieve certain tasks; Ease of Use: the efficiency and effectiveness with which one can achieve these tasks; Flexibility: the extent to which a system can adapt to new task ....

.... separately and sequentially to reach an endpoint in control space, should be reflected by the input device [32] The research on performer instrument compatibility performed in this context has generally aimed at improving the usability of the interface [93] 94] for which estimation Shackel [81] provides four criteria: user learning, ease of use, system flexibility and user attitude. The focus of research performed in this context is on finding a new control surface configuration or control method that reduces the motor and cognitive load applicable to either specific groups or all ....
