The Linear Movement Apparatus can be used for motor learning tasks and assessing temporal or spatial memory. This device has been used in motor learning and neuroscience studies, and motor skill evaluation. The Linear Movement Apparatus consists of an optical encoder that accurately measures the switch displacement. The subject moves the superior switch located in a cube at a specified distance or speed without external clues. To evaluate the subject's ability to judge these dimensions, an LCD readout displays the distance and time in which the switch in the cube is moved. This unit employs highly accurate electronic position encoders.

The system measures time estimation, speed and distance; basic for aviation personnel, professional drivers and high performance athletes.

Subjects use their hands for positioning the switch on top of the cube at a distance or speed selected by the experimenter or evaluator. Results are evaluated in terms of accuracy in estimating distance or speed correctly (distance/time). The subject must judge distance or speed on visual perception, force and/or previous experience skills.
