A motion-capture system using video cameras can record
human motion by measuring the position of markers at
tached on a human subject, and enables to reconstruct human motion on a computer. However, the capable information is basically limited to the positionaldata, such as hand
position, limb’s posture, and so on. If the force data related to human movements could accurately measure from
the video data as well as the positional data, it would be
much useful to analyze human behaviors and to construct
a more realistic virtual reality. The present paper proposes
a vision-based estimationmethod of the applied force from
a human to deformable objects without a force sensor. The
proposed method is simple but can estimate the applied
force accurately by means of the mechanical properties
of deformed object corresponding to its deformation form.
The preliminary test using a soccer ball is carried out to
demonstrate the effectiveness of the proposed method.
