Are you interested in hi-tech products£¿ Here are some that you might find at the market pretty soon.
CX-1
Tired of dragging your bag through busy airports£¿ Then you might want to consider CX-1. The smart suitcase uses facial recognizing software to follow its owner as he / she is checking in or heading to the gate. Though CX-1 can only move at a speed of up to seven miles per hour, a tiny tool enables owners to keep track of the suitcase's location. It is expected to be sold on the market by late 2018.
Aibo
Sony's latest version of the Aibo robotic dog is almost as fun as the real thing-but much less work. The pet dog can recognize its owner, obey several commands, and even recall the behavior that pleases its master the most. Aibo can also learn new tricks, take photographs, and over time, develop its own unique personality.
Forpheus
Forpheus,an "athletic" robot developed by Japanese technology company Omron. It teaches users how to play ping-pong. The 10-feet-tall machine uses a camera and artificial intelligence to track the ball's speed and can predict the ball's direction correctly. The smart Forpheus can also quickly test its player's abilities and adjust the playing level, making the game fun.
Black Box VR
Though many people determine to go to the gym once a week, few reach their goal. Black Box VR wants to change that by turning hard exercise into fun video games. Using it, gym users will find themselves fighting enemies, including big creatures-all while getting exercise.
