Virtual Imaging Peripheral for Enhanced Reality

2. Project Overview Our project, code named Virtual Imaging Peripheral for Enhanced Reality or VIPER, is an augmented/virtual reality system. It will track a handheld unit’s location and perspective and use this information to find the location of a camera position in a virtual environment. Through a LCD screen on the handheld unit the user will see the virtual environment at the cameras location as if the handheld unit was a window into the virtual world. As the user moves the handheld unit around a table top sized environment the handheld unit’s actual and virtual perspective changes, allowing for different viewing angles of the virtual space.

3. Project-Specific Success Criteria • An ability to communicate time stamp data using RF between the base unit and handheld unit. • An ability to display images to the LCD display. • An ability to estimate the angle and position of the handheld unit with respect to an origin point using accelerometer, gyroscope, compass, visual data, and ultrasonic data. • An ability to find angle displacement of the handheld unit’s front face relative to the IR beacon origin using mounted camera. • An ability to find distance from base to handheld unit using ultrasonic emitter and receiver.

5. Environmental Impact of VIPER • Manufacture • Materials • Normal Use • Hazardous Leakage • Power Concerns • Disposal/Recycling • Proper disposal of various components

6. Environmental Impact of VIPER - Manufacture • Biggest issue during production is the inclusion of lead in the product and chemicals used during the manufacturing process. • Easy to fix • Use a manufacturer that is RoHS compliant and RoHS compliant components. • RoHS (Restrictions of Hazardous Substances) • Lead • Mercury • Cadmium • Hexavalent chromium • Polybrominated biphenyls • Polybrominateddiphenylsether • Acrylamide

7. Environmental Impact of VIPER – Normal Use • LCD screen hazards • If broken the backlight of the LCD can release mercury • Use led backlights instead • Battery hazards • Possible leak or fire if exposed to extreme heat or abuse • Make it clear to treat the battery intelligently in manual • Power Hazards • Base Station does not have power saving mode • State that base station should be unplugged when not in use

8. Environmental Impact of VIPER - Disposal/Recycling • Disposal of the LCD screen • Make the LCD screen easily removable and give instructions in manual on how to find locations that recycle or properly dispose of them • Disposal of Battery • Make the battery easily removable and give instructions in manual on how to find locations that recycle or properly dispose of them • Remainder of Product • Give instruction on how to find a location that recycles or disposes of electronics

9. Ethical Considerations of Viper • Possible effects on animals • May make it unattractive • How precise is the device • Limits markets • Making people sick • Warnings on extended use • Make cause accidents • Warn people to be aware of their surroundings
