Status Update

• Concept - A silent, portable, comfortable,
  battery-operated, phone activated, vibrating
  pillow cover.
• Project Idea Finalized
• Parts Purchased and destroyed a massage chair
  from Bed, Bath Beyond (for research). Other
  parts have been ordered and being shipped.
• Customer Survey Informal surveys show mostly
  positive feedback

• Failure Case 1
• Pillow battery dies
• Bluetooth out of range

• Failure Case 2
• User does not wake up

Risks Mitigation
Risks Mitigation
- Hardware too bulky for pillow cover to be comfortable Strategic placing of hardware (pun intended) like batteries and wires and testing padding
- User not waking up (vibration not enough, user tosses pillow etc.) Using variable motors and cell-phone speaker backup
- Hardware disconnect due to rough user interaction (no pillow fights) Testing with a variety of connectors and padding
- Not water-proof (drool proof) Having warning labels. Just kidding, water proofing inner layers.
- Battery power not enough Using rechargeable batteries or AC/DC converters
- Vibrations too noisy Including variable motor settings
