Nowadays, the selection of software programs is developing at a rapid pace. The introduction of new features and functions, as well as entirely new applications on the market make it hard for an individual to master a large variety of them.

Video tutorials are currently the best way to quickly become accustomed to a new software. However, he constant rewinding, pausing and switching back and forth between informational content and the applied application, leads to persistent interruptions of the workflow.

A hardware device that allows you to operate platforms like YouTube while simultaneously working in another program could solve issue. The device would have to have the core capability of switching between two programs, as well as basic video interface functionality like rewinding, skipping and pausing.

A Lo-Fi prototype was created using Arduino, 3D printing, and foam. It was then employed in usability tests designed to assess the concept's legibility, evaluate interaction patterns, and identify potential areas for improvement. This step proved crucial, as although the initial concept was well received, the testing revealed that it lacked essential functionality, such as the ability to skip chapters or view a video with an in-picture viewer.

To fill the gaps in functionality, we added a sliding potentiometer that made the rotary encoder movable from side to side. The slider was placed inside the housing, with a cut out for the turn knob. The final Hi-Fi prototype hides components by encasing them in 3D printed elements.

Our prototype was reimagined through renderings, providing insight into how the interface could look. The final product enables a seamless workflow across various scenarios, whether someone is using a secondary monitor or is limited to only the screen of their laptop
