Motion intention detection plays an important role in human-computer interaction

which is the guarantee of natural and reliability in human-computer interaction processing. There is a potential relationship between the upper limb mechanical information and motion intention. The production and change rule of human upper limb mechanical information is explored under the external constraints. And motion intention detection based on upper limb mechanical information can be realized through developing motion intention information acquisition system and carrying out experiments. Human upper limb force information can be obtained by multi-dimensional force sensor

and combined with human motion intention

relationship of the upper limb movements

the motion intention and upper limb force information is found out. A method for human motion intention detection based on the upper limb mechanics information is found.
