Assistive Technology for Teaching Autistic Children’s
1. Introduction
Autism is a complex disability that appears during childhood and affects interaction, social skill,
communication, and self-regulation. The use of assistive technology increased from the last few
decades due to the accessibility of the digital age and computers. Technology enhancement is
increasingly used to enhance the interaction of children with Autism Spectrum Disorder. By using
the robot the children learn the color, differentiation between colors, and also improve their
interactive behavior and communication. The Application helps parents to see their child
performance report of interaction with a robot.
1.1 Purpose
This document describes the requirement and specification of Robot and application. The Purpose
of this document is to understand the requirements and design constrains briefly in order to clearly
understanding the features of the product, roles of user and their responsibilities.
1.2 Scope
This product helps in the process of learning for Autistic Childs. According to the study, 85% of the
child with autism perceives colors more intensely as compare to children displaying normal
development. Through this robot and application, we aim to improve the learning behavior of
children and to show their live performance to their parents. Our robot uses the sensor to detect the
color of the object and then generate alert through the speaker. The Robot will send an alert on
application installed on the parent Smartphone when it's their child's turn and to stay connected to
view the performance of their child.

2. General Description
Robot is designed to improve the learning behavior of child and to inform the parent about their
performance through smart phone Application.
2.1 Product Perspective
The main feature of the robot is to detect the color and tell what color is detected. On testing, the
mode robot detects the specific color according to input. Buttons are set to colors for inputs. The
robot sends the alert to the application according to the child's turn. Through the application, parents
can view their child's performance.
2.2 Product Functions
The robot detects the color and speaks the color name.
The robot informs their Parent when the attendance of the child is marked on the robot.
The application notifies when it's their child's turn.
Robot provides child performance report to parent through an application installed on their
Smartphone’s.
2.3 User Characteristics
Mainly robot is designed for the learning of Autistic Child. Child have slow learning process they
need to repetitive behavior to learn something. Robot needs to repeat the color of ball 5 times for
effective learning.
2.4 General Constraints
Red color could lead to tantrums and even pain associated with certain parts of body.
2.5 Assumptions and Dependencies
Robot and Application are connected to the Wi-Fi.
3. Specific Requirements
Robot has option to register child ids.
Robot have front basket for input in which child puts the ball.
Robot has to recognize the color of the ball.
Robot has to speak the color of ball and also in alphabetically.
Robot send the notification of child turn to their parent on marking the attendance by the teacher.
Application shows the notification and also generate alert on receiving the notification from robot.
Application shows the performance report.

3.1 External Interface Requirements
3.1.1 User Interfaces
There are two interfaces one for parent and the other for the child.
Parent receives notification or alert through an application installed on their android phone. The
application has an Interface that shows the performance of their child.
The robot has a basket on its front side in which students put a ball and the robot tells the color of
the ball.
Xml for Application front end display.
3.1.2 Hardware Interfaces
LDR
LED
MICROPROCESSOR
Microprocessor detects the variation in voltage when object is placed between LDR and LED and
generates result according to Datasets.
3.1.3 Software Interfaces
Assembler or C Compiler is used for microprocessor programming.
Android studio is used for Smartphone’s Application development.
3.1.4 Communications Interfaces
Smartphone’s Application supports all type of android versions.
