Bionic boots are high­tech boots that can help you reach running speeds comparable to professional athletes like Usain Bolt. The extremely light boots are just like springs inspired by the Achilles tendon (跟腱) of ostriches (鸵鸟) or Kangaroos, lending the wearer more force while running, with a spring in their stride(大步；步幅)．

　　The boots are invented by Keahi Seymour, who has always been fascinated by the effortless run of ostriches (鸵鸟), the fastest running birds on the planet, with a top speed of 45mph. He has been working on this kind of shoes for several years, producing dozens of prototypes (模型) in the process.

　　"The bionic boots may be the transportation in the future，" he explained. "They are meant to make a man run faster, inspired by the fast land animals. The boots are made up of a carbon fiber composite exoskeleton (外骨骼), and also aircraft­grade aluminum. So the lightest materials were applied to providing the most efficient form of transportation."

　　Seymour recently showed the capabilities (能力) of his latest version of bionic boots at the Maker Faire in New York. They can help anyone reach speeds of up to 25mph, which is the same speed as a slowly moving car. In comparison, Usain Bolt, the world's fastest man, has clocked a top speed of 27.44mph.

　　Not just watching a film ...

　　RealCine - virtual① reality② for everyone

　　This presentation③ will give you some information about RealCine: how it works, why it is better than a film, and how it can be used in other ways. The RealCine experience will amaze④ you, and you will agree that this is an extraordinary technology that deserves to be developed further⑤.

The technology behind RealCine is virtual reality (VR). Unlike a film, where a passive audience watches and hears what is happening on a screen⑥， RealCine puts you into the action and connects with your senses of sight, hearing, smell and touch in an active way. Imagine that a VR user⑦'goes' sightseeing⑧ in the Himalayas. Not only will he or she feel every step of climbing Mount Qomolangma, but the user will also experience⑨ the cold, smells, sights and sounds of the surrounding environment; he or she will enjoy a feeling of happiness⑩ and a sense of achievement⑪ upon reaching the top⑫.
