designer's own words:
Nowadays, with the help of the smart phones, users can inform their family members they will arrive home soon, maybe within fifteen minutes. The pre-announced messages induce friendly anticipations of the family members. The new design, Be HOME pet collar accessory, employs and shares this anticipation function to the pets.
The “Be HOME” is an innovative IoT pet collar accessory. As soon as the pet owners get off work, they can transmit signals by smart phone App to the “Be HOME”. When the collar accessories receive the signals and the devices will express specific sounds and vibrations. After couple times of interactions between the owners, the pets, and Be HOMEs, the pets will adapt and understand the meanings conditionally. Once the collar displays some specific messages, the pets' anticipations are aroused for the appearances of the lovingly owners.
