  For Uma: Mouse Clicking Mechanism
  Uma has difficulty in clicking the mouse due to her fine motor weakness.
  
  Our Ideas
  Ease her to work with computers in her profession by compliant clicking mechanism for efficient use of the pressure for button click as she had to use Autocat mostly in work.

  For Bharat: vehicle operation by hand
  He has difficulty operating four wheeler as he is wheelchair bound.
  Our Idea:
  Apply pressure on brakes by connecting a long shaft/rod to the brake and other end to hand. The images show a thin rod which connects to brake and big part which is hand operated.

  Mouse Clicking Mechanism:
  First prototyping
  -Initially, we sketched, modelled and 3D printed the Mouse clicker.
  - Uma find less flexible to use. She was not able to press mouse button properly.
  
  Comments
- Prototyping
  0
  Second Prototyping
  -Afterthat, we thought of making it more flexible and easy to press
  - Then, we remodeled and re 3D printed it.

  For Idea-2 :Ring for clicking mouse:
  First Prototyping:
  -Firstly, we fabricated a ring for clicking mouse with standard measurements.
  -uma found this model to be tight, and unpleasent.

  second prototyping:
  - After that, the ring was made flexible after measurements.
  - Weight was introduced above the ring and was better than the previous one.
  - Then we proceeded to the next design.

  First Prototyping:
  -Firstly, we fabricated the ring for clicking mouse.
  - The model was printed in relatively very small size .
  - It was reprinted again to match the standard measurement.

  This is the only prototype consisting of more than one parts. Individual components were printed separately and then assembled later.
  Comments
- Prototyping (Idea - 5)
  0
  Only the design of this prototype is possible and 3d printing the model is not feasible due to extremely large size . In this model, only brake is manually controlled however it can be further stretched to control accelerator and clutch.
