“There is a direct union of oneself with a motorcycle, for it is so geared to one’s proprioception, one’s movements and postures, that it responds almost like part of one’s own body. Bike and rider become a single, indivisible entity; it is very much like riding a horse. A car cannot become part of one in quite the same way.”

Apple Watch: Faulty Taptic Engine Slows Rollout
Wall Street Journal‎ - 3 hours agoThe taptic engine, a key component of the Apple Watch, made by one of two suppliers was ...


According to the Wall Street Journal, some taptic engines supplied by AAC Technologies Holdings Inc., of Shenzhen, China, started to break down over time. That prompted Apple to scrap some finished watches.
The report offers one possible explanation why some people must wait until the summer to get the watches they ordered, even though Apple began shipping the high tech timepieces on April 24.
Apple's product launch mishaps are infrequent but not unprecedented. In 2010, the late Steve Jobs had to defend "Antennagate," the episode in which some iPhone 4 owners complained of dropped calls when they held the phone a certain way.
Proprioception (/ˌprpriˈsɛpʃən-priə-/[1][2] pro-pree-o-sep-shən), from Latin proprius, meaning "one's own", "individual," and capiocapere, to take or grasp, is the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement.[3]本體感覺,又稱肌肉運動知覺是一種對肌肉各個部份的動作或者一連串動作所產生的觸覺,稱呼為「自我知覺」。可是對某些人來說肌肉運動知覺自我知覺不同在於保持平衡的觸覺。例如:當內耳受到感染,就會影響平衡。這個感染損害了自我知覺而不是肌肉運動知覺。受感染的人能夠走路,但是只能靠視覺來保持平衡而不是自我知覺。這些人閉著眼睛是不能走路的。
