| Implementing Movement Parallax for Laparoscopy - Getting there |
 |
  |
Initial experiments on the use of movement parallax for laparoscopy showed the principle
was effective also on small scale. Main difficulty was the technical implementation of the mechanism to move the camera inside the tip of
the laparoscope.
This was somewhat simplified after realizing that the camera does not have to move inside the tip of the laparoscope since the abdoman is
inflated providing enough room to move part of the laparoscope. |

| The initial prototype showed the technical feasibility of the idea. The second prototype (shown above) had a diameter of 5 cm, but
demonstrated the basic principle.

|
| The third prototype, shown above, was only twice the size of a normal laparoscope. Despite having found a feasible solution, the technical implementation reamined the main obstacle
between a nice idea and practical solution. A small side-step towards shadow parallax was taken
before arriving at a practical technical solution. |
