Final project review presentation MSD P09011 - Visual and Auditory Object Recognition testing apparatus & objects Andrew Chorney- Project Manager Michael Goldberg- Lead Engineer Timothy Bukowski- Industrial Engineer Mahmudul Khan- Electrical Engineer Martin Martinez- Mechanical Engineer Jason Hess- Industrial Engineer

To assess the beluga whale’s visual and auditory perception abilities 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

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

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
