Fundamental study of an intelligent machine instructed by finger motions: ∼psychological effect of transfer functions on approaching motions∼

In an interface that enables an intelligent machine to bring a thing to a human in response to the human\´s manipulation, the intelligent machine\´s approaching motion is required to take account of the human\´s state of mind to serve effectively as his or her companion. In this paper, the patterns of intelligent machine motion are determined by adopting transfer functions that consider finger position directing operation as input, the target positions of intelligent machine as output. By changing the transfer function or adjustable parameters, differences are seen in the response characteristics of the intelligent machine. Therefore, it can be expected to give a different impression in human. Motion properties of the intelligent machine, which is appropriate for human states of mind, are examined using SD method. As a result, human feelings to the intelligent machine generated by human instructions are represented by the factors of "lively" and "mild". In addition, two patterns of transfer function with appropriate parameters, which can form desirable movements considering human psychology, are identified.
