This document describes a wireless sensor device that can be controlled through hand gestures for home automation and security alerts. It allows controlling devices and appliances, providing security alerts through SMS, capturing video images, locking/unlocking systems, and opening/closing applications and the PC through hand gestures mapped to commands. The device aims to make human-computer interaction more intuitive through contactless gestures. Future work includes improving dynamic image processing and event handling, as well as using gestures to control games, robots, and crisis management systems.

2. Introduction
 The role of computer has grown very fast in
society. The interaction with the computing devices
has been advanced in such a way that it becomes
the necessity of today’s life.
 We introduce some typical methods based on the
action recognition by the sensors.
 Gesture operation can be considered as an easy-to
understand and easy-to-use method to operate the
PC in an easy-to-understand and easy-to-use
without using traditional mouse or keyboard.
 Aims to design systems which can identify human
hand gesture as an input and uses these gestures in
order to control a device through mapping of
command as an output.

3. Trends
Security has been an issue since the very inception of
technology. Thus, an important part of this mechanism is
providing security alerts to banks through SMS GATEWAY to
transmit messages to nearest help centers.
Controlling the home appliances and electronic gadgets.
Providing security alerts.
Capturing images during video streaming.
Locking and unlocking the system.
Opening the applications on PC and enables voice
response.Switching off PC.

4. Future scope
 We are also able to handle dynamic image
processing and event handling accordingly.
 The use of hand gesture interfaces to control
computer games, robots, medical visualization
devices and crisis management systems allows an
expressive, natural and intuitive way of
interaction.

5. Interest Areas
To make the interaction more natural
and intuitive with operating systems like
Windows, I’m interested in developing
another layer of interaction which
consists of more physical interfaces like
rotating knobs with fingers to change
volume, pulling threads to pull your
dashboard from above, make a cross to
close any program, and flick your hand
to switch between applications.
