CES By Noel Randewich and Jeremy Wagstaff LAS VEGAS/SINGAPORE (Reuters) – Despite the hoopla, wearable gadgets like wristwatches for checking your text messages or eyeglasses that capture video are unlikely to make a splash with consumers anytime soon, given the clumsy designs, high prices and technological constraints of many of the current offerings. That is the conclusion drawn by many industry executives and analysts who trolled the vast exhibition halls of the Consumer Electronics Show in Las Vegas this week. Stacy Rasgon, a semiconductor analyst at Bernstein, spent a day at CES busily snapping photos of every fitness band, watch and other wearable device he came across. People are throwing spaghetti against the wall to see what sticks. Sony Corp , Samsung Electronics Co Ltd and Qualcomm Inc showed off new or recently launched smartwatches, most of which act as extensions to cellphones, letting users check messages and appointments.
