The purpose of this paper is to assist the computer input for the person with hand disabilities, and to construct a system that can be inexpensive and easily implemented. Thus, the authors propose a combination parameters of “Euler angles” and “Translations” under body movements to perform mouse scanning behaved as alternative cursor. In other words, this is a trial to replace the pointing functionality of the mouse by utilizing “Translations” in neck or waist movements in addition to the “Pitch/Yaw/Roll” in face orientations. There are similar ways of thinking in the past, however, the usage of parameter combination as well as the possibility of practical realization can be hardly found. As a result of our experiments, it is to give an indication that our method can be applicable to function as a mouse scanning to some extent in spite of the simple system configurations by utilizing the current technique in both hardware and software. On the other hand, there are some problems remained as further considerations, such as, operability experiments by handicapped subjects, the system configurations in wireless linkage, and so on. without any attachment to the human head [3]. The problems are still remained for the eye movements in visual fixation, narrow recognizable view range, etc. Our scheme seems to be common with the conventional method in terms of facial behavior, non-contact, or non-wearing, however, it becomes rather simple concepts by extracting Euler angles and Translations in head movements.
