This document proposes a simple and inexpensive solution for astronauts to communicate while in space using sign language. The prototype involves gloves with sensors that detect finger bending and hand movements. The sensors send data to an Arduino board which processes the signals and displays the translated words on an LCD screen. The proposed system uses flex sensors to measure finger bending, an MPU6050 sensor to track hand movements in six axes, and an Arduino Uno microcontroller to convert the sensor readings into displayed words on an LCD screen. It provides a potentially cheaper alternative to existing costly space communication methods.

1. Connect: can
you hear me
now ?

2. 1)Communication in space:
“There are hundreds methods that already
exist for astronauts to communicate in space
that are very costly and ineffective”
2)No matter
“There is no field (air) that allows sound to
travel in space”
3)Astronauts vs deaf
“Astronauts lose their hearing in space and
become deaf”

3. Solution: dealing with astronauts as deaf
An easy, simple and inexpensive solution consisting of
Prototype is relatively easy compared to all NASA devices
Prototype:
1) Gloves contains a set of sensors, Arduino, and circuits.
2) Screen to display
the translation of the signals
received from the gloves.

5. How does this project work:
1- Inputting methods:
-Flex sensor: This sensor is used to measure
the bending in each finger through the change
in resistance, as the flex sensor is considered
a variable resistance that changes according to
the bending of the fingers.
Resistance value lies between approxmitly10KΩ to 40KΩ.

6. (MPU6050): It is the most crucial sensor in the circuit,
as it reads the sex axes of hands’ movement.
In other words, this sensor can determine the exact
position of the user’s hand in six directions
(x, y, z, gx, gy, gz) to ensure
the accuracy (design requirement).

2- Processing Methods
-We will use Arduino Compiler to upload the codes into the
controller, which takes the readings of the input sensors,
compare and convert them to words.
3- Outputting Methods:
Output Speech, which was converted
in the processing methods, is written
on LCD Arduino.
