Problem Statement

• Trauma care physicians rely on realistic medical
  simulators to expose them to life-threatening
  situations before treating on real patients
• ED physicians express concern that current human
  patient simulators inadequately simulate
  physiological responses of the eyes.
• Current simulated eyes are expensive, require
  high maintenance, and have limited range on
  simulated responses.
• Problem
• How to design a cost-effective realistic eye
  simulator that can implement a broad range of
  anatomical capabilities ?

Performance Criteria

• 1. Size
• Needs to fit SimMans eye sockets
• 2. Control
• Must be controlled using a computer/joystick
• 3. Response-Time
• Should have minimal delay when reactingto user
  input
• 4. Functionality
• Must perform basic eye function
• Movement
• Pupil dilation/constriction (1 - 10 mm)

4
Primary Objective

• Develop a relatively inexpensive eye simulator
  for SimMan that can implement a variety of eye
  functionalities pertinent to emergency training
  scenarios.

5
Solution Description
Using microdisplay technology we can implement
3D-graphics software to model anatomical eye
features and physiological responses.
6
Goals

• Create realistic eye features by integrating 3D
  computer graphics with microdisplays.
• Develop a computer-controlled eye simulator that
  is esthetically pleasing
• Create a cheaper alternative option for eye
  simulators than those that are currently on the
  market.
• Simulator implements physiological responses such
  as pupil dilation/constriction, blinking, and eye
  movement

7
Factors

• Using micro-displays lowers both cost and
  maintenance as opposed to mechanical simulators.
• 3D-Studio Max offers an effective method that can
  increase both the quality and number of various
  physiological response necessary for a realistic
  medial scenario.

8
Performance Metrics

• Test physiological responses with basic
  fundoscopic procedures.
• Test eye functionality by using real-time
  simulation
• Survey physicians to validate performance.
• Determine whether or not there is a statistical
  difference in the number of deaths between
  SimMan with eyes and those without eyes.

Past Work

• Toured Vanderbilt University Simulations and
  Technology facility.
• Observed simulated cesarean section to
  understand the controls needed for our
  eye-simulator.
• Learned to use the basic functions of 3D-studio
  max.

11
Current Work

• Measuring dimensions of SimMan eyes in order to
  find the appropriate micro-display products
  available.
• Contacted eMagin for OLED Microdiplay systems and
  Faunhaufer for VCB.
• Researching the various types of physiological
  responses that occur in the eye after particular
  drug applications.

12
Future Work

• Begin to model detailed 3D images of the eye
  including the retina.
• Order LCD screen and test the animation quality
  and performance.
• Implement a mechanical technique to move the LCD
  screens by using a joystick.
• Test our prototype in a medical scenario.
