User interfaces for the command and control of systems usually integrate several types of interaction elements: physical space, hardware and software. Within such kind of environment, operators have to complete their tasks manipulating hardware and software elements that are distributed in the physical space. However, current tasks description notations do not take into account physical and hardware aspects beyond manipulation of input devices such as mouse and keyboard. This paper proposes a set of extensions to task modeling techniques in order to represent user goals and activities when interacting with distributed hardware and software user interfaces. These extensions are demonstrated with the HAMSTERS-XL notation and tool. These models can be analyzed and simulated to support identification of cumbersome tasks, motoric and perceptive efforts and sub-optimal UI distributions. We present how such information can be used for improving the user interface of the hardware and software distributed user interfaces. We exemplify the approach on a simple but realistic example: The Philips Hue light bulb system.
