Nowresearch about the human factorsis crucial. This can be divided intofour areas.(1) TLe needs telecommunicationsmust satisfy--needs can be extrapolated from currentbehavior.(2) The technological alternatives available--importantdevelopments are being made in transmission andswitching equipment and user terminals. (3) The effectiveness of thealternatives for meeting the needs--studies should combine the laboratoryand outside world and should focus on typical consumers aswell as business users.(4) The secondary effects--impact studies aredifficult and usually begin after the impact has been felt. Animpact study approach can be to ask what constraints would beloosened by the presence of a technological development. For example, lower costtelecommunications would remove one constraint on longdistance calls and could lead to new group associations.Several disciplines are relevant toresearch that is needed, including informationtheory, management studies, psychology, sociology, urban and regionalplanning and geogTaphy.

It may also be classified into person-person, person-machine, ormachine-machine communication. This paper is concerned only with two-way, person- person, telecommunication. Moreover it is concerned with such systems not as items of electronic hardware, but aschannels of human comm- unication. By what criteria must the developing system oftelecommunications be judged, if it is to play its full partin facilitating human capable communication?And are we, in the present state of research, of applying such criteria? The technological fallacy Technological feasibility is a necessary, butnot a sufficient criterion for innovation.The fact that a particular telecommunications system, such as the video-telephone, istechnologically feasible is no justification for its development (1). It is extremely dangenius to argue that such developments form somekind of 'logical' and even inevitable progression. To take an example from the field of ,trans- ;ortation, the fact that civil aircraft have steadilyincreased in airspeed does not prove that this trend can beusefully extrapolated must be ad infinitum. At each stage of innovation the probable costs weighed against the probable benefits, alternative coursesof action being compared on this basis.And of course the great weakness of technology as a strategic criterion is that there always arealtern- ative courses of action, each of then technologicallyfeasible. In the case of telecommunications, although thevideo-telephone is technologically feasible, so also is therapid transmission of paperwork by facsimile (2). Technological feasibility in itself is no guide to the priority whichshould be attached to each alternative. Imitation of the irrelevant /nstead of regarding telecommunication as driven on by atech- nological dynamic, it is possible to regard it as progressingtowards the increasingly accurate simulation of face-to-facecontact. A difficulty of such an approach is that accuracyexists along many 4 would involve an dimensions (3).

It must also be bornein mind that an increase in accuracy, necessarily particularly if it occurs along asingle dimension, will not lead to an increase in realism,and may even be counter-productive. remarkable ability Experiments in perception showthat the brain has a it (5), both to sift out the salientfeatures of the signals'reaching fragmentary and incom- and to construct out ofthese features, however It has been said that the senses plete, a coherent picture of theworld. rather they provide do not give us a pictureof the world directly; about what lies lefore us (6).Attempts at evidence for check$mg hypotheses Thus the listener to a too much realism may frustratethis process. actors .4lich, radio play may be able toform in his mind an image of the product2on while innacurate, is far morerealistic than any theatrical proscenium, scenery and greasepaint.A with its artificialities of which invites us by its imitationof depth to stereoscopic photograph, impression treat it as a real view, createsby its lack of movement an two-dimensional photo- of unrealistic stillnesswhich is absent from a reproductiz.0 of face-to-face graph (7).

The businessman in his office, or the lecturer on aplatform, will often feel more comfortable if he can take up adefensive position behind a piece of contact, the furniture (84. Because, compared with face-to-face telephone provides a reduced channelof communication, it represents the same kind of privacyshield. And because, unlike the face-to-face visit, the telephone does not invoke thecustomary associationu of host and guest, it is free of theobligations and commitment inherent in face-to-face communication (9). But the outstanding feNture oftelecommunication is that it com- bines in one medium the important advantawsof mail and face-to-face distance, thus communication. Like mail, it is largely indiHerent to providing an enormous geoaraphical range ofpotential contact (10).
