The invention provides a space operation type mouse, and relates to a mouse, which aims at solving the problem of the traditional mouse that the assisting of operation carriers is needed in use, the attitude of a user operating the mouse is limited in the use process, and the influence on the body health of the user is caused. When the space operation type mouse is used, a user can hold the mouse by hand through various methods, or wear on an index finger, an attitude collecting module in the mouse can collect the displacement of the mouse, the displacement is directly sent into a PC (personal computer) after data processing, the assisting of any operation carrier is not needed, the human-machine interaction is natural, a keyboard is controlled through gestures, and the limitation is avoided. The space operation type mouse adopts the software low pass filter principle, the positioning is accurate, the alignment speed is high, and the advantages of trackball mousse and optical mousse are integrated. When the space operation type mouse is used, the attitude of the user is not limited, so the problem of cervical vertebra diseases due to long-time use is effectively avoided.
