Azoteq's scroll wheel feature for active pens and other small diameter human input devices

Users are accustomed to scroll wheel type user interfaces. Azoteq’s ProxFusion sensors now enables small diameter pen and barrel type scroll wheels. Whereas existing active pens are impacted by bulky designs, Azoteq can provide a 10mm total diameter barrel type scroll wheel.

Further advantages of the Azoteq solution is:
Low power consumption - Auto low power modes less than 5uA
Higher resolution
Additional capacitive touch or inductive sensors
Less mechanical constraints and therefore more design freedom.
Better mechanical durability
Easy to design in limited space

Numerous functions can be executed by scroll wheel. These include:
Scroll up/down
Zoom in/out
Rotate 3D objects in AR / VR space
Volume adjust

The IQS624 now enables industrial designers to design the world’s thinnest barrel type scroll wheels.

The IQS624 Hall effect, capacitive touch and inductive combination sensor is available for mass production goods. Samples and evaluation kits available through Azoteq’s distributors and online resources available in the ARM mbed community. Just one of the many combination sensors from Azoteq’s ProxFusion family.
