PPTX Remote Control

1 / Introduction

Project Vision

The PPTX Remote Control is an autonomous electronic device engineered to streamline presentation delivery without heavy reliance on traditional user-interface peripherals.

By moving controls off computers and into a single ergonomic object, it helps educators, speakers, and students focus on audience interaction over technical mechanics.

2 / System Capabilities

Core Functional Components

5D Joystick Navigation

Implements continuous 2-axis sliding control for fluid slide backward/forward motions and digital document panning.

3D AirMouse Control

Decodes physical wrist gestures in space via an I2C spatial motion block into smooth, on-screen pointer trajectories.

Dual Pointer System

Combines a built-in hardware low-draw physical laser with software virtual display highlighting hooks.

3 / Social Responsibility

Digital Accessibility & Inclusion

"True technology must lower barriers, not construct them."

Motor Skill Optimization

Simplifies microcomputer interactions for users facing physical motor control constraints, reducing complex multi-key inputs to centralized ergonomic gestures.

The driverless architecture guarantees immediate use across diverse educational settings, preventing isolation induced by configuration requirements.
