Hand Keyboard

Portable Bluetooth Keyboard That You Will Be Able To Use Everywhere

As Part Of Our Final Project In The Hemdamakers Course, We Were Asked To Develop A Wearable Project.

At First Our Idea Was To Make A Glove That Can Control A Robotic Arm Wirelessly Using A Bluetooth Connection. The Glove Will Send Values From The Arduino And The Potentiometer To The Robotic Arm And As A Result, You Would Be Able To Control The Robotic Arm.

While Designing The Glove And The Arm We Had The Idea That Instead Of Making The Glove Control An Arm, The Glove Would Be A Portable Bluetooth Keyboard That You Will Be Able To Use Everywhere.

At The End We Decided To Make The Keyboard And We Called The Project Hand Keyboard.

How The Glove Works:

On The Back Of The Glove Under The Thumb And Also Under The Index Finger There Are Potentiometers That Connect To The Fingertips With A Fishing Wire. When You Move Your Fingers The Potentiometers Rotate And Send Their Values To The Arduino And Then The Arduino Transforms The Signal To A Character (Depends On The Values It Received) And Shows The Output In The Arduino Ide - Pc Display, Currently Via The Serial Monitor, But In The Future, We Would Like To Do It Wirelessly.

The Potentiometers Return To Their 0 Value Thanks To The Rubber Band That Is Attached To The Sensor With Special Parts We Design.

The Thumb Act As A “Shift” Key That Changes The Letters That The Index Finger Will Be Able To Send. Think Of It Like The Old Nokia Phones, The Thumb Chooses The Key And The Index Finger Press It, Each “Button” Have 2 Letters To Shift From And Not 3 Or 4.

In This Project We Focused On Designing The Glove For People With Disabilities That Are Not Capable To Communicate Verbally And Have The Ability To Move Fingers A Bit.
