Develop and test haptic displays
With the success of smartphones, touchscreen technology has become mainstream. Now, innovative user interface concepts use haptic or tactile feedback to give touchscreens a unique feel. Such vibrations or force feedback can make operation significantly easier and intuitive by, for instance, letting the user know through touch which virtual button is under their finger or whether it was successfully activated.
Laser vibrometers are vital to the continuing research, development and quality control of haptic feedback devices. 3D motion data precisely describes the in-plane and out-of-plane vector components for a full characterization and visualization of the haptic signature. In production testing, vibrometers from Polytec assure the desired feel with laser precision.
