External Virtual Keyboard
๐ง External Virtual Keyboard for Desktops
By Ronen Kolton Yehuda (Messiah King RKY)
๐ก Introduction: A Virtual Keyboard – No Physical Keys Required
The era of mechanical keyboards is evolving. As user interfaces become more dynamic and adaptive, the demand for flexible, digital, and space-saving input solutions is rising. This article introduces a groundbreaking concept: the External Virtual Keyboard — a fully interactive touchscreen keyboard panel designed for desktop computers.
It’s not a projection. It’s not a pop-up on your screen. It’s a dedicated multitouch screen panel that acts as your keyboard — with software-defined layouts, dynamic responsiveness, and connectivity to any desktop PC.
๐ฅ️ What It Is
The External Virtual Keyboard is a standalone touchscreen device, shaped like a full keyboard, that connects to a desktop computer and replaces the need for a physical keyboard.
Key Components:
- High-resolution touch display (capacitive)
- Built-in microcontroller or embedded OS (optional)
- USB-C and/or Bluetooth connectivity
- Customizable keyboard software
- Plug-and-play support for Windows, macOS, and Linux
๐ Connection Options
- USB-C Wired Mode: Plug the device directly into a desktop for fast, stable input.
- Bluetooth Mode: Wirelessly connect to any modern PC.
- Dual Mode Support: Users can choose between USB and wireless with a switch.
๐ง How It Works
- The device itself has a touchscreen panel.
- A custom app or onboard software renders the keyboard UI.
- Once connected, the computer recognizes it as a standard keyboard input device.
- The user types directly on the screen — which may include:
- Tactile feedback (via vibration)
- Dynamic layout switching (e.g., from QWERTY to DVORAK or gaming mode)
- Language switching, shortcut buttons, emoji panels, and macros
- Optional audio feedback (click sounds, etc.)
๐งฉ Integration with the Villan Ecosystem
This product is compatible with the Villan V1 OS and also works seamlessly with external Villan devices such as:
- SmartShoe™ (as computing source)
- +Device
- SmartBracelet & SmartHat
It may also serve as a secondary touchscreen input for AI systems, virtual assistants, and accessibility tools.
๐ Software Options
The virtual keyboard system can operate in two models:
- Tethered software: The PC runs the software and renders the UI on the keyboard screen via USB.
- Standalone software: The keyboard runs its own OS or firmware and acts like a standard HID device (keyboard).
๐ฆ Form Factors & Design
- Full-sized version – resembles a standard mechanical keyboard
- Compact version – for minimal desk setups or portability
- Transparent or backlit glass models
- Multitouch and gesture support
๐ Use Cases
- Desktop users who want a clean, modern desk aesthetic
- Programmers and creatives who switch keyboard layouts
- Accessibility users needing customizable interfaces
- Gamers who want configurable hotkeys and macros
- Public use terminals (libraries, airports, hospitals)
๐ง Patentability
Yes, this concept is patentable if:
- The method of integration between the touchscreen and PC is unique.
- There is a novel layout, switching logic, or physical design.
- Firmware/software ecosystem is proprietary and extensible.
A utility patent could protect the system for up to 20 years, especially if the keyboard dynamically adapts, connects to smart wearables, or integrates voice/gesture AI.
๐ Conclusion
The External Virtual Keyboard bridges the gap between smart surfaces and user interaction. It's not just a keyboard—it’s a modular, digital input surface for the next generation of desktops, wearables, and computing.
Just as we redefined the laptop with a virtual keyboard embedded into the base, we now offer the same innovation externally — for any desktop in the world.
๐งช Technical Overview: External Virtual Keyboard (EVK) – A Standalone Touchscreen Input Device for Desktop Systems
By Ronen Kolton Yehuda (Messiah King RKY)
1. Abstract
The External Virtual Keyboard (EVK) is a modular, standalone touchscreen device designed to function as a primary keyboard input for desktop computers and other computing systems. Unlike on-screen virtual keyboards or physical mechanical keyboards, the EVK introduces a hybrid input approach by offering a dedicated capacitive multi-touch panel that connects via USB or Bluetooth and renders software-defined keyboard layouts dynamically. This article details the system architecture, connectivity protocols, firmware structure, use-case integration, and patentable features of the device.
2. System Architecture
2.1 Hardware Components
| Component | Description |
|---|---|
| Touchscreen Panel | Capacitive multitouch LCD or OLED, ≥10.1″ diagonal, 1920×1080 minimum resolution |
| Microcontroller / Embedded CPU | ARM Cortex-M7 or low-power ARM Cortex-A series (e.g. A7/A55) |
| Bluetooth Module | Bluetooth 5.0 LE module for wireless HID transmission |
| USB Interface | USB-C (with HID device mode support via USB HID class) |
| Power Supply | USB-powered or internal battery (Li-ion 2000–5000mAh) |
| Haptic Driver (Optional) | For localized vibration feedback on keypress |
| Audio Speaker (Optional) | For click/tone feedback |
| Touch Controller IC | Capable of supporting ≥10 simultaneous touches |
| Enclosure | Aluminum or polycarbonate housing with anti-glare tempered glass overlay |
2.2 Firmware & OS Layers
Depending on the configuration, the EVK operates in either:
A. Tethered Mode
- Host PC runs EVK software agent.
- Agent streams layout images and input mapping to the EVK display.
- Touch data is sent from EVK to PC via USB HID or Bluetooth HID.
- Lightweight firmware required on device (embedded Linux optional).
B. Standalone Mode
- EVK runs its own layout rendering engine (e.g., Qt or SDL-based).
- Keypress detection and USB HID reports handled locally.
- Configuration stored in onboard flash.
- Can switch profiles without host software.
2.3 Logical Input Flow (Standalone Example)
[Touch Input] → [Touch Controller IC] → [MCU Logic Unit]
3. Communication Protocols
| Layer | Protocol | Description |
|---|---|---|
| Wired | USB HID | Standard keyboard reports, plug-and-play |
| Wireless | Bluetooth HID | LE HID profile for seamless wireless input |
| Config Transfer | JSON/XML via USB or OTA | For importing/exporting layouts, languages, macros |
| Optional Debug | UART over USB | For firmware development and testing |
4. Software System
4.1 Layout Engine
- Layouts are stored in JSON or XML format.
- Each key includes:
- Label
- Action code (standard HID code, macro, or script)
- Size/position
- Visual style
Example key definition:
{
4.2 Host Agent (Optional for Tethered Mode)
- Windows/Linux/macOS application
- Functions:
- Sends current layout to EVK via USB
- Receives touch events as key input
- Layout switching by software context (e.g., typing in code editor → coding layout)
5. Use Cases
| Use Case | Features Leveraged |
|---|---|
| Desktop Typing | Standard QWERTY + haptic/audio feedback |
| Programming | Hotkey/macros, IDE-specific layouts |
| Gaming | On-screen macros, transparent overlays |
| Accessibility | Enlarged keys, visual-audio cue integration |
| Public Terminals | Durable, wipeable flat glass; fixed layout |
6. Patentable Claims (Examples – Not Legal Advice)

- A method of rendering and switching dynamic keyboard layouts based on host application context or user profile.
- Integration of embedded firmware for layout control and input emulation in the absence of host software.
- A user-configurable layout system where each key’s dimensions, code, and appearance are dynamically defined.
7. Competitive Advantages
| Feature | Advantage |
|---|---|
| No physical keys | Silent, durable, washable, customizable |
| Full layout flexibility | Multilingual, macro, accessibility support |
