Abstract
A method of testing a haptic device that includes an actuator and has a first weight includes placing the haptic device on a test fixture that has a second weight that is greater than the first weight. The haptic device is placed on the test fixture so that the actuator within the haptic device is substantially close to the center of gravity of the test fixture. The method further includes causing the haptic device to generate haptic effects via the actuator, and measuring the acceleration of the test fixture during the haptic effects.
Claims26
A method of testing a haptic device of a first weight and comprising an actuator, said method comprising:
- placing the haptic device on a mass having a second weight that is greater than the first weight and having a first center of gravity, wherein said haptic device is placed on the mass so that the actuator is substantially close to the first center of gravity;
- causing said haptic device to generate haptic effects via the actuator;
- and
- measuring an acceleration of said mass during the haptic effects.
A system for testing a haptic device having a first weight and comprising an actuator, said system comprising:
- a test fixture having a second weight and having a second center of gravity;
- an accelerometer coupled to said test fixture;
- and
- a processor adapted to be coupled to said haptic device to cause said haptic device to generate haptic effects and to receive acceleration measurements from said accelerometer;
- wherein said second weight is greater than said first weight, and the system tests said haptic device when said haptic device is placed on the test fixture so that the actuator is substantially closed to said second center of gravity.
A method of testing a haptic device comprising:
- placing the haptic device on a test fixture so that an actuator within the haptic device substantially coincides with a first center of gravity of the test fixture;
- activating the actuator to generate a haptic effect;
- and
- measuring an acceleration of said test fixture.
A computer readable medium having instructions stored thereon that, when executed by a processor, causes the processor to test a haptic device of a first weight and comprising an actuator, said processor:
- determining if said haptic device is placed on a mass having a second weight that is greater than the first weight and having a first center of gravity so that the actuator is substantially close to the first center of gravity;
- causing said haptic device to generate haptic effects via the actuator;
- and
- measuring an acceleration of said mass during the haptic effects.
