Automatic sleep and wake motion detectionRelevant data twitter, calendar, to-do list, etcEasy to use, touch-free

3Specifications

Voice Recognition RangeUp to 10 FeetVoice Recognition Success Rate>75% Auto-Turn offAfter 2 minutesCold Boot-Up90%Specifications broken down into four categories: voice recog, control pc, temperature system, gesture recognition

Appropriate voice distance

Quick to to turn on and off (safety and user convenience)

High temperature accuracy (for again safety and make sure it just works as it should)
