Evaluate of methodology
(Methodology of CONTROLING MACHINE USING HAND GESTUER)
Power circuit
The arduino output terminals are connected to the motor driver’s input (L293D) and the motor output is connected to a 2 motor DC input. This circuit is used to feed the project control circuit with the required power.
Control circuit
In this circuit the device will be connected Arduino UNO with Accelerometer sensor where that
Arduino UNO
Arduino is a single-board microcontroller meant to make the application more accessible which are interactive objects and its surrounding. The hard ware features with an open-source hardware board designed around an 8-bit Atmel AVR microcontroller. Current models consists a USB interface, 6 analog input pins and 14 digital I/O pins that allows the user to attach various extension boards.
Accelerometer sensor
o Accelerometer sensor is used to recognize the hand gestures
o It recognizes the acceleration of the hand in both x and y –axes
o It produces different numerical values corresponding to the direction acceleration
Driver motor circuit (L293D)
Supply voltage, VCC1 (12V)
Output supply voltage, VCC2 (12 V)
Input voltage, VI (7 V)
Output voltage, VO (–3 VCC2 + 3 V)
In this circuit each pair of driver is a complete reflection motor H suitable for solenoid applications, the camp diodes must be used for high-speed exothermal output of the transient L293D, these diodes are combined to reduce system complexity and overall system size AV is separate from Vccz and the arduino is connected with buttery 5V the motor driver is connected to a 9V battery in order to operate the system.
Threats
1. The use of Bluetooth technology for remote control in the device
2. The presence of electronic control devices help to work the control department required to operate the device
3. Use a driver motor circuit because it is a repeatable device and contains a separate battery and this is in order to resist the system of the hardware using a stream and low voltage for this is considered a strong point for this project
Weaknesses
1. Not fully explain the methodology and identify some points that may be used for programming
2. The occurrence of error when installing the circuit or in the test
3. The presence of a person does not work, leading to delay of the project
Merits
1. This device is not expensive for those who use it
2. In terms of its methodology will be easy to use
3. This period of work the device is large
Demerits
1. Relatively difficult to debug
2. May be less efficient when used
(Methodology of HAND GESTURE RECOGNITION USING ACCELEROMETER FOR DISABLED)
It is possible to recognize the hand and this through the use of the rapid counter for the disabled of the most important components contained in this device is the central processing unit (MPU-6050) and this is because it is one of the simplest things used to deal with the movement of remote control devices, which is specific to the indicators of movement is also used Microcontroller (MSP430g2553) is also a Bluetooth module (HC-05)
Weaknesses
- This device can be used in a variety of small applications
- If quick movements are used in this project may lead to any error
- There are not many competitors in the market
- Strength Point
- Very simple in terms of ingredients
- A new idea by a large proportion
- Performs sensing with precise movements
Merits
- Inexpensive
- Because of the presence of some modern electronic elements make it fast responsive
- Works remarkably well
Demerits
- Do not stay as it is but less effective with the passage of time
- This device can stop at any time
Methodology of Hand Gesture Controlled Wheelchair
In this way, a special camera is used to capture 30 images per second for hand movements, such as a video camera, which is connected to the USB controller. Through these snapshots, you determine if one of the fingers has moved or not and then you deal on this basis to Converts those images to black and white and then shows which finger is moving which gives the controller a signal for the turn
Strength point
- Using the camera is something new and useful
- You feel the movement remotely
- Opens up new horizons for a sense of things
Weaknesses
- Can be subject to the problem of sudden shutdown of work because all digital electronic devices are vulnerable to this problem
- It can have negative effects on the images and therefore will not be accurate in the sense of movement
- Is relatively slow from other devices used in sense?
Merits
- Do not consume large electrical capacity
- Do not restrict or harass the hand-
- Does not cause skin damage or allergies-
Demerits
- Any movement can have a negative effect on images
- Can be suddenly disrupted if used in a stormy environment
- Less efficient and faster with time and therefore not given correct readings
