1、Digital Whiteboards for Design: Lagging Issues When Drawing Wireframes
While brainstorming and mapping out user flows on the whiteboard proceeds smoothly, the entire workflow completely breaks down the moment you attempt to transition from the conceptual ideation phase to the actual creation of wireframes.
Older versions of Android may be the root cause of the issues you are currently experiencing. When writing or adding annotations, you must use a stylus—specifically, the original stylus provided by the device manufacturer. This is because the stylus driver software has been specially optimized to ensure seamless compatibility with the Android operating system running on this digital whiteboard; consequently, you cannot use third-party styluses that have not undergone this level of deep-level compatibility testing.
2、Its built-in dual-system digital whiteboard (Windows and Android)
This morning, our Sales and R&D teams gathered in a small conference room (accommodating up to 10 people) to experience our latest product launch: the JYR189808H "Integrated Conference Terminal."
Thanks to its built-in dual-system architecture—featuring both Windows and Android—we were able to run Adobe Photoshop files within the Windows environment while simultaneously conducting presentations and making annotations in the Android environment. The ability to switch seamlessly between the two operating systems via floating shortcuts significantly boosted our work efficiency, saving us a considerable amount of valuable time.
