Disabled people don't have the opportunity to use devices like computers and especially Smart Phones. The existing market solution to this problem uses high end technologies like image processing, electromyography, bite sensor etc. which are very expensive and not reliable to use. Our device, iURIS, is a simple and low cost solution which acts as a human computer interface for the assistance of differently abled people.
It uses Inertial Measurement Unit to detect the orientation of head according to which the hovering action of the mouse is controlled.
It uses eye blink sensor to perform the clicking action of mouse. Also our gadget gets wirelessly connected to the blue-tooth enabled smart phone or computer using a blue-tooth module.
The HID compatibility is obtained using an HID compliant Device.
The user then, with this technology can use all the features of mobile phone like making calls, sending text messages, playing games, controlling electronics appliances using IOT app

Our device can be directly mounted on spectacles and can be used right away. The MPU6050 on our device gives raw readings of the head orientation which are used for further processing. To remove the drift and error in readings obtained from MPU6050 filters such as Kalman and Complementary are applied such that these readings can be converted into x and y co-ordinates for the mouse pointer. An Arduino pro Micro/ Arduino Nano can be used for the processing of the raw readings obtained from MPU6050. An additional feature of this device is that it is wireless. All the x and y co-ordinates are transmitted to the target computer or mobile phone using a bluetooth module HC-05. 2 bluetooth modules are used, one as a master and other as a slave.

The people, our product is targeting, are physically disabled people who have a minimum active neck movement.

Our product is made with the aim of providing independence for physically disabled people who can’t use technology for their betterment.

Physically disabled people will be benefited by our product.

On further advancements, this device can also be used by normal people for entertainment purposes like Virtual Reality (V.R.), gaming, etc.

    After everything was finalized, many designs were thought for iURIS and implemented. 3D files for iURIS were designed using Autodesk. They were 3D printed and assembled. Casing for each component was carefully designed keeping in mind the user's comfort. Also the Li-ion Battery was chosen due to its consistency and better life. The 3D printed product is uploaded.

  • Making iURIS Wireless

    Till now every test we performed was wired and the device was powered through a laptop. However, this was uncomfortable and there was a need for making the device wireless. We selected HC-05 bluetooth module to add the wireless feature on our device. HC-05 transmitted the x and y co-ordinates obtained from Arduino Pro Micro. Another HC-05 received these co-ordinates and fed it to another Arduino Pro Micro connected to the target device (computer or mobile phone). The first Arduino Pro Micro was used only for processing of x and y co-ordinates where as the second Arduino Pro Micro acted as the HID compatible device.

    After properly applying filters to MPU6050, Arduino based Pro Micro was studied. Pro Micro was selected for this because of its HID compatibility. It can act as external mouse as well as keyboard for any computer or mobile phone. The HID compatibility of Arduino Pro Micro was implemented and tested to get reliable results.

  • MPU6050, Filters

    MPU6050 was studied and the data obtained from it was analyzed. Application of Kalman and complementary Filters was implemented on the raw readings. With some changes in the formulas for Kalman and complementary filters, thee raw readings were onverted in the for of x and y co-ordinates.
