Head tilting motion is one of the available body parts to operate the assistive products such as auto wheel chair due to the fact that the head motion is unburdened and non-contact operation can be done. Here, we measured the head tilting motions and investigated its characteristics to construct a head tilting interface. In the experiment, the tilting angle of the head and the back of the neck during conversation, blowing, and daily motions were measured by the three dimensional accelerometers and the time series of the data was investigated by the FFT analysis. The experimental results said that the neck and head interlocked with each other and the bowing motion, which is conscious movement, was 0.3[Hz]. During conversation, the nodding motion, which is unconscious movement, was less than 3[Hz]. When using smartphones, watching videos, and writing something, the movement was less than 1[Hz]. We could find the differences between the conscious and unconscious motions.
