SOMA haptic testing

Haptic testing is becoming increasingly important due to the widespread proliferation of switches and buttons in many products, irrespective of sector.

SOMA haptic testing systems as a complete solution

More and more customers, especially in the automotive sector, are placing great value on good haptic qualities in their control elements. A precise switching sensation, low friction in the moving elements, play-free design both in the rest position and during actuation are only some of the criteria for good haptic switching properties. SOMA haptic testing enables you to measure these subjective properties.

Using haptic testing for the objective evaluation of subjective properties

Do the buttons on a product have a pronounced mechanical switching point and is this the same for all buttons? Does the rotary switch engage at the correct positions and are the potentiometers smooth or stiff enough? These and other properties can be quantitatively tested using haptic testing from SOMA Test Systems and be assured for the relevant product.

The properties can be evaluated by recording force/path measurement curves or torque/angle of rotation curves and with configurable algorithms depending on the desired behaviour. Evidence of electrical functionality of the element and its peripherals is often required as part of haptic testing – SOMA has suitable solutions for this as well.

Haptic testing systems: individually customised

SOMA haptic testing offers haptic test systems that are individually customised to the inspection task as a complete solution for use in production.

In addition to realising the stimulation and measuring technology using market-leading components, the scope of services includes assembly of all the peripherals required for haptic testing, for example a test control system with evaluation and data connectivity, parts recording using contacting, electrical interface or robot positioning of the test head.

SOMA haptic testing systems can either be designed for manual feeding, concatenated in fully automatic systems or also in combination with other test equipment. A modular structure and the use of flexible systems also enables subsequent adaptation of the haptic testing system to changing production and test requirements.
