The day hu­mans achieve the abil­ity to read one an­other’s minds grows ever closer thanks to

al­terego, a de­vice cre­ated by mit me­dia lab grad stu­dent ar­nav Ka­pur (above). The pro­to­type hard­ware wraps around the ear and jaw­line and makes it pos­si­ble for peo­ple to talk, in a man­ner of speak­ing, with­out say­ing a word: to or­der pizza, switch TV chan­nels, pro­fess undy­ing love, or warn of an on­com­ing train. al­terego works

by pick­ing up the neu­ro­log­i­cal sig­nals the brain ac­ti­vates when you read or speak silently to your­self. it sends those sig­nals via blue­tooth to a cen­tral com­puter

for in­ter­pre­ta­tion. The wearer can hear what oth­ers “say”

back via bonecon­duc­tion head­phones. in­ter­per­sonal chat is cur­rently lim­ited

to sim­ple words and phrases, but an in­de­pen­dent mit pa­per re­cently found that within its vo­cab­u­lary, al­terego’s speech com­pre­hen­sion is ac­cu­rate to 92%. Will we soon (loudly) bid adieu to the age of awk­ward small talk and yelling at siri? We’d of­fer our best guess, but pre­sum­ably you can tell what we’re

think­ing by now.
