Example Haptic Feedback Applications – Barcode Scanner

Using Haptics In Handheld Devices - Barcode Scanner

Tactile feedback can be used as a great alternative to replacing annoying audible alerts. Anyone who has spent any length of time at a supermarket checkout can relate to the annoyance of the repetitive monotone beep. Similarly, with touchscreens, they are now more commonplace in white goods, but many still use sounds to notify the user it has registered the input.

This can be easily removed by using simple vibration technology to interact with the user. Electric torque wrenches, medical instruments, and barcode scanners (like the example below) are just some of the light handheld devices that can benefit from adding tactile feedback.

Barcode Vibration Motor Placement Example

Barcode Vibration Motor Placement Example

As barcode scanners are usually quite light and the operator doesn’t need protective clothing, the vibration strength does not need to be very strong. This opens up a wide selection of vibration motors to meet different product weights, voltage/haptic-feedback supplies, or other design constraints.

Easily mounted in the handle, a cylindrical ERM vibration motor like is perfect for creating vibrations directly into the grasp of the operator. Now when scanning codes the user will receive feedback for a successful scan, or unsuccessful, along with a variety of other notifications like low batteries, errors, etc.

When coupled with an LED the tactile feedback augments the design to make using the product much more pleasant, not just for those using the product but also for those in the vicinity. Improving your products through the addition of new features demonstrates your company has the technical expertise to stand above your competitors.

For help in positioning the vibration motor to maximise the effect of the vibration, we have a series of Application Bulletins that cover mechanical mounting. We also have a larger guide to haptic feedback for more information or contact us with any questions.
