Solutions
Education case study
Dual-Screen Original Handwriting Smart Podium
A purpose-built classroom podium combines device control, courseware preview, live annotation and synchronized presentation in one ergonomic teaching station.
01
Background
The context
One step solution to education
At the front of many classrooms, teachers still manage separate controls for lighting, air conditioning, projectors and curtains while moving between a laptop, wall display and whiteboard.
The YFD320 brings those tasks together with a 19-inch upper control display, a 23.8-inch lower screen for courseware and annotation, a battery-free EMR pen and integrated audio in a lectern-grade unit.
02
Challenges
What the workflow must solve
Built around real operating constraints
Natural handwriting
Make live annotation and formula writing feel direct and responsive, like a familiar whiteboard.
Multi-screen coordination
Let the teacher preview content and face students while the class sees the main presentation display.
Simple device integration
Connect laptops, storage and wireless display tools without complex cabling or configuration.
Visual comfort
Keep the display readable in changing classroom light and under ceiling reflections.
Ergonomic operation
Position the writing surface for comfortable standing use during a full teaching session.

Solution
Haveways approach
Hardware and software designed as one system
Control, present and annotate
The upper screen acts as a classroom control hub while the lower screen provides courseware preview and direct pen annotation.
Dual-touch handwriting
Capacitive touch supports gestures and navigation; EMR input provides high-precision battery-free pen writing for notes, formulas and diagrams.
Synchronized teaching display
Triple-screen linkage pushes annotated content to the classroom display with low-latency synchronization so the teacher can continue facing students.
Human-centered connectivity
USB 3.0, Type-C and HDMI connections, shortcut controls, integrated audio and a 12-degree writing angle simplify everyday classroom use.
