2. Project Description  Primary Objective:  Design an apparatus that will be used to present three-dimensional objects in a match-to-sample procedure  Purpose:  To assess the beluga whale’s visual and auditory perception abilities  Scope of Project:  1 Testing Apparatus  2 sets of 42 Target Objects  Testing Procedure  Supporting Documentation  Budget: $3500

3. Primary Design Criteria  Operator and whale safe  Quiet operation  Durable & weatherproof  Corrosion-proof  No external power  Compact and mobile  1-person operation  Able to block whale and trainer’s view of both object sets  24” total design width  1-3sec target time between object set display, 5 sec max  5lb max object weight

10. System Testing Results: On-site Tested in Mystic Aquarium on 5/15/09 Apparatus functioned as designed Trainers examined apparatus and objects for whale safety Trainers approved of the design and its functionality Recommendations from trainers: Add labels for sample and choice pulleys Ensure double blind test by creating a shield to block view of experimenter from the whale Tether apparatus to beach Replace top shield Replace coated wires Adjust to swing apparatus to left instead of right Add ability to roll up shields out of the way Ensure all objects are whale safe, i.e. no sharp edges
