Abstract
An apparatus is provided for assessing a persons ability to perform tasks requiring hand and eye co-ordination. A gaze tracker 6 images a person's eye in order to determine their direction of look. In the context of a vehicle system, a steering wheel direction sensor 12 is provided to determine the direction of the steering wheel. Data from the steering wheel sensor and the gaze tracker is compared by a data processor 14 which looks for correlations between the data sets and uses this correlation to determine whether the person 2 is fit to drive or not.
Claims17
A method of measuring a person's ability to perform a task which require control of at least one of a person's limbs, the method comprising:
- measuring a first motion which comprises the movement of at least one of the person's limbs or the movement of a device operated by the person;
- measuring a second motion made by the person in order to acquire visual data in order to perform the first motion;
- and
- comparing the first and second motions to obtain a measure of performance.
An apparatus for measuring a persons ability to perform a task requiring control of limb position the apparatus comprising:
- a first input device responsive to motion of at least one limb;
- an eye-tracker for determining the person's direction of gaze;
- and
- a data processor for comparing an output of the first input device with an output of the eye-tracker and for making the result of the comparison available.
