Online Handwriting Recognition using Motion Sensor based Pen Device

With the advances in current technology, we see a rapid increase in availability, but also a demand for intuitive interaction between man and computer. While recognizing has been developed graphically based on the vision, it has some limitations, such as running a camera in one place, with the advantage of using motion sensors to develop a portable device.

Combining the rapid development of man-computer technology and the growth of portable devices, a handheld device integrated with motion sensors has been proposed to recognize handwriting by capturing interaction writing paths.

The goal of this Handwriting Recognition project is to develop a portable pen movement base for the online reorganization of letters or handwritten sensor numbers. Users can use this pen to write letters or numbers in the air.

Signs generated by hand movements are generated by in-device and transmitted to the PC for processing and additional signal recognition via a wireless motion sensor module. A handwriting recognition algorithm will be developed for recognition signals using measured by the sensor.

A portable device will be developed base pen with motion sensors (triassic accelerometer, compass and gyroscope), a microcontroller and a wireless transceiver. This pen-based motion sensor can be used to enter numbers or letters in a free space at normal speed.

The sensors are used to detect hand movements. The microcontroller collects the hand motion sensors and wireless transmitters signals in the main PC processor for processing and recognizing the additional signal via a wireless transceiver.

A Handwrite Algorithm (DTW) recognition is implemented to perform handwriting recognition using the signals detected by the integrated sensors in the device.

Touch Screen Based Wireless Home Automation Using Zigbee

When an order is placed by the customer, table_id and order number is transmitted to the coordinator and an acknowledgement is sent automatically to that end device i.e. table and a LED is switched ON at the table device. Now once the order is ready, owner presses the respective button to the table whose order is ready, then the LED at end device starts blinking which will be as an acknowledge to the customer saying the order is ready.

All these information is being stored in data base and will be displayed by using a projector or any other displaying device. Now if another order has to be placed by the customer then he needs to first press any button to make the blinking LED off and then click the respective button for the order and this repeats. Thus the ordering an item at restaurant is being easier and simpler.

SOFTWARE REQUIREMENTS:

a) IAR Embedded Workbench (MCS-51 7.30B)
b) Z-Stack (CC2430 – 1.4.3 – 1.2.1)
c) Byte Wedge Standard for Database

HARDWARE REQUIREMENTS:

a) Intel Pentium based system with Windows XP.
b) Keypads for connecting to the Battery Board at the End Point.
c) Zigbee

BLOCK DIAGRAM


WORKING PRINCIPLE

This is an Touch Screen Based Wireless Home Automation Using Zigbee Technology application that has tables as End Device and the owner as a Coordinator. The number of tables as per this application is 4 and can be changed according to the user’s requirement. Each table has its own unique table_id. This has to be assigned to the end device in order to differentiate each table.

The table can place an order having four items ranging from 1 to 4 using the four switches available. Here we are sending 11, 12, 13 and 14 from the four switches respectively where for example in “11”, the first digit is the table_id and second digit is the order. As the table_id must change for all the four end devices, the first digit shall be changed for every table.

Once the order is placed by the customer, order is being received by the Coordinator and for acknowledgement coordinator automatically sends back a message and an LED is switched ON at the end device. Now once the order is ready, owner presses the respective button to the table whose order is ready, then the LED at end device starts blinking and the food is being served by the waiter boy.

All these information will be displayed by using a projector or can also be displayed by any other displaying device. Now if another order has to be placed by the customer then he needs to first press any button to make the blinking LED off and then click the respective button for the order and this repeats.

ADVANTAGES

1) No need of man power.
2) We can save time.

APPLICATIONS

1) The counter and customers are connected in a wireless Zigbee network to make the service more efficient.

Microcontroller based Smart Parking Control System

This Smart Parking Control System project Designed With Microcontroller attempts to cut the time to park the vehicles in the lot and help the motorists to recall the exact parked space. Motorists often spend a significant amount of time to park their vehicles in the parking lots during peak hours. They also may not remember the parked space of their vehicle precisely, while picking up the vehicle.

To solve this problem, an automated vehicle parking system is designed which serves the motorist to find a space for his vehicle within less time. The system displays about the details of freed-up parking spaces. The waiting time to park the vehicle can be reduced by providing this vacant space information to the motorists before he/she enters the system.

The system recognizes the vacant space and displays automatically, this display system can be provided at the entrance of the main gate, so that while entering in to the parking space, the motorist can find his parking place without anybody’s direction.

To sense the vehicle at parking place, infrared sensors are used; the output of the sensors is fed to micro-controller and according to the received information from the sensors, the controller displays, that the particular parking place is vacant or full. For the demonstration purpose three sets of sensors are used to simulate three parking sites.

The system is designed such that, when all parking sites are filled and there is no space for another vehicle, automatically the gate will be closed. To simulate this, stepper motor is used and the controller drives the motor, a small arm of 10″ is coupled to the motor shaft, which simulates either the gate is opened or closed. For displaying the information LCD panel is connected at the output of micro -controller.
