OBJECTIVEOBJECTIVE

Implementation of Human Computer Interaction with RF Communication.

INTRODUCTION

User activity

• Physical

• Cognitive

• Affective

Types of Interfaces

Command Line Interface (CLI)

Menu Driven Interface

Graphical User Interface (GUI)

Natural Language Interface

Existing Technology

• Increasingly we are recognizing the importance of

human computing interaction (HCI), and in particular

vision-based gesture and object recognition.

• Existing Models uses a video device to control the

mouse system.

Working of Existing Method

Real-Time Video From Web Camera

Converting Video into Images and processing them

Extraction of different colours from Images

Performing different mouse actions by assigning different

colour pointer

Working of Mouse using RGB Technique

Algorithm

• Image Subtraction Algorithm

•Time to act.•Complexity to work.•Need of a camera ,total operations are depends on Camera Functionality

PROPOSED RF-MOUSE

• Implementation of Mouse Controlling using Radio Frequency Communication.

Chronos Watch

The eZ430-Chronos is a highly

integrated, wireless development

system that provides a complete

reference design for developers

creating wireless smart watch

applications.

Development Software

• Both IAR and CCS have free code-limited versions supporting the

Chronos. The projects for Chronos are delivered in both full source and

pre-compiled library options to avoid any code size restrictions.

• Code Composer Studio v5

• IAR Embedded Workbench KickStart

RF Access –USB

•High-performance RF transceiver based on the

market-leading CC1101

•High sensitivity (–110 dBm at 1.2 kBaud)

•Frequency range: 300 – 348 MHz, 391 – 464

MHz and 782 – 928 MHz

CONCLUSIONCONCLUSION

• Virtual Mouse Control with Human Computer Interaction

based on Color Detection model provides small distance

communication around 5-10 feet.

• The integrated Mouse control with the help of hardware which

Establishes a Wireless Communication between user and

computer and provides communication up-to 20-30 feet

distance.

FUTURE SCOPEFUTURE SCOPE

• Implementing in 2.4 GHz Frequency range .
