    A mechanized "oracle?" is helping Bell Telephone Lab-oratories predict the future in communications devices and systems.

    The oracle i s "Sibyl." a computer-like machine de-veloped by Bell Laboratories engineers and psychologists-It can simulate the action of man kinds of communications de\ices. Through Sibyl, new kinds of telephone service can be evaluated without the considerable expense of building actual equipment. Observing and recording users" reactions to the simulated equipment. S i lnl provides indications of how users would react to proposed new s\>tems features and equipment.

    Sibyl, for example, is used to test the reaction of Bell Laboratories people to experimental push-button telephones. Each test subject has a push-button telephone in his office and he uses it in the ordinary course of his busi

    ness. But the set is not cnneoted dire-ctlv t the lcal PBX : it is connected through Sib\ L w iiicts. performs the ?p-cial signaling functions required lv such a pu^h-huttoit *ele-prione. I this u a \ . pu>h-button telephone -erv ice i- s h en to a group of people without m*difv ins the P B \ . or pro-viding eompleteK inr-truniented |usrn-buttsi telephones.
