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

Architecture • Our basic diagram has not changed. Serial port bluetooth module Arduino Nano Blue-tooth enabled android phone Solarbotics VPM 2 Vibrating Disk Motor Double A’s • Other parts: Pillow covers (purchased), padding (researching), connectors (researching)

Use Cases • Normal Use Case • 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
