Assistive Communication Glove for the paralytic
Project Area of Specialization Wearables and ImplantableProject SummaryHumans greatly rely on acoustic communication for expressing their feelings, needs, and messages. Unfortunately, paralytic individuals can only move a single limb, such as a hand, in a limited way due to which they face extreme difficulty in communication. Such individuals may immensely benefit from an assistive technology that helps translate their movements into acoustic communication. Currently, such devices are locally limited in availability, usage, flexibility, and costly. We propose a cheap communication device that can be attached to the individual limb and can be set to translate the movements according to the required need of the caretakers and paralytic individuals. The project will involve five flex sensors and one accelerometer sensor to identify finger movements in real-time and display them on a screen and acoustically convey them.
Project ObjectivesThe main objective of the project is to:
- Implement a hardware unit to acquire acceleration and finger movements
- Translation of finger and hand movements to speech through accelerometer and mobile device
- Bluetooth communication between mobile phone and hardware unit
The project implementation relies on Arduino Nano for receiving input from sensors and encoding the signal into binary. The signal shall then be transmitted to the android device with the help of a Bluetooth module. Further processing will be carried out by the android application. The application will contain the code for first setting the application so that selected actions are mapped to their voice output. The application will set the voice commands and actions. This process is based on collecting repeated samples of a specific action and computing an averaged signal for the action.
To use the sensor-based glove, user will have to connect his android phone with the sensor-based glove using Bluetooth. Finally, when an input is received from the user in real-time through the sensor-based glove, the signal is forwarded to the android application. The application matches the signal to the closest saved averaged signal.
The main benefit of the application is assisting paralytic individuals in articulation of their thoughts and needs.
