\nV roce 2010 byla Sjednocen\u00e1 organizace nevidom\u00fdch a slabozrak\u00fdch (SONS) oslovena firmou Prisma Teknik s nab\u00eddkou nov\u00fdch akustick\u00fdch tla\u010d\u00edtek. Ty pom\u00e1haj\u00ed zrakov\u011b posti\u017een\u00fdm v bezpe\u010dn\u00e9m a samostatn\u00e9m p\u0159echodu p\u0159es p\u0159echody, na kter\u00fdch jsou nainstalov\u00e1ny semafory.<\/p>\n

V sou\u010dasn\u00e9 dob\u011b nevidom\u00fdm slou\u017e\u00ed akustick\u00e1 klep\u00e1tka, kter\u00e1 ve v\u011bt\u0161in\u011b p\u0159\u00edpad\u016f funguj\u00ed spolehliv\u011b, av\u0161ak maj\u00ed jednu nev\u00fdhodu. V p\u0159\u00edpad\u011b vy\u0161\u0161\u00edho provozu, \u010di v\u011btrn\u00e9ho a de\u0161tiv\u00e9ho po\u010das\u00ed jsou h\u016f\u0159e sly\u0161et.<\/p>\n

Nevidom\u00fd se tak setk\u00e1v\u00e1 se situacemi, \u017ee h\u016f\u0159e nach\u00e1z\u00ed samotn\u00fd p\u0159echod a nen\u00ed si v\u017edy jist\u00fd, zda v dan\u00fd moment m\u016f\u017ee p\u0159ej\u00edt. O to v\u011bt\u0161\u00ed nejistotou proch\u00e1z\u00ed, kdy\u017e mus\u00ed p\u0159ej\u00edt slo\u017eit\u011bj\u0161\u00ed k\u0159i\u017eovatku, kde je um\u00edst\u011bno n\u011bkolik akustick\u00fdch tla\u010d\u00edtek a nejde snadno ur\u010dit, kter\u00e9 pat\u0159\u00ed k pot\u0159ebn\u00e9mu p\u0159echodu.<\/p>\n

Nov\u00e1 technologie slibovala, \u017ee akustick\u00e1 tla\u010d\u00edtka budou um\u011bt reagovat na prost\u0159ed\u00ed. Laicky \u0159e\u010deno, budou se zesilovat a ztlumovat podle hlasitosti provozu a klimatick\u00fdch podm\u00ednek. Mezi dal\u0161\u00ed v\u00fdhody m\u011bla pat\u0159it vibra\u010dn\u00ed signalizace, kter\u00e1 by usnadnila p\u0159echod hluchoslep\u00fdm, ale p\u0159inesla i v\u011bt\u0161\u00ed jistotu nevidom\u00fdm.<\/p>\n

Po n\u011bkolika jedn\u00e1n\u00edch bylo rozhodnuto, \u017ee dojde k testov\u00e1n\u00ed technologie firmy Prisma Teknik. Byl vybr\u00e1n p\u0159echod na pra\u017esk\u00e9m N\u00e1m\u011bst\u00ed m\u00edru, kde byly ide\u00e1ln\u00ed podm\u00ednky na testov\u00e1n\u00ed.<\/p>\n

Paraleln\u011b s testem v Praze m\u011blo doj\u00edt i k testov\u00e1n\u00ed v Brn\u011b, kde se tak\u00e9 pohybuje velk\u00e9 mno\u017estv\u00ed nevidom\u00fdch lid\u00ed. Zde v\u0161ak nastaly prvn\u00ed probl\u00e9my.<\/p>\n

„P\u016fvodn\u011b jsme si p\u0159\u00e1li ud\u011blat test ve v\u00edce lokalit\u00e1ch, p\u0159inejmen\u0161\u00edm je\u0161t\u011b v Brn\u011b, kv\u016fli neochot\u011b firmy Prisma Teknik se za sv\u00e1 tla\u010d\u00edtka postavit \u010di se by\u0165 jen \u010d\u00e1ste\u010dn\u011b pod\u00edlet na n\u00e1kladech testov\u00e1n\u00ed, se v\u0161ak nakonec testovalo jen v Praze. Firma Prisma Teknik nebyla mimo jin\u00e9 ochotna dokonce ani jen zap\u016fj\u010dit sv\u00e1 tla\u010d\u00edtka, o jejich opakovan\u00e9 neschopnosti opravit vadn\u00e9 v\u00fdrobky nemluv\u011b,“ \u0159\u00edk\u00e1 Jan Urb\u00e1nek, kter\u00fd m\u00e1 v SONS \u010cR odstra\u0148ov\u00e1n\u00ed bari\u00e9r na starosti.<\/p>\n

V Praze tedy do\u0161lo k nainstalov\u00e1n\u00ed akustick\u00fdch tla\u010d\u00edtek na N\u00e1m\u011bst\u00ed m\u00edru firmou \u02c7A\u017dD, kter\u00e1 cel\u00fd test tak\u00e9 financovala.

To, \u017ee nov\u00e1 technologie v\u011bt\u0161inou pot\u0159ebuje n\u011bjak\u00e1 po\u010d\u00e1te\u010dn\u00ed nastaven\u00ed, aby fungovala spr\u00e1vn\u011b je norm\u00e1ln\u00ed, ale podle Jana Urb\u00e1nka se firma Prisma Teknik chovala neochotn\u011b, odstra\u0148ov\u00e1n\u00ed pot\u00ed\u017e\u00ed j\u00ed z pravidla trvalo p\u0159\u00edli\u0161 dlouho a ne v\u017edy do\u0161lo k jejich \u00fapln\u00e9mu odstran\u011bn\u00ed.<\/p>\n

Nejv\u011bt\u0161\u00ed p\u0159ednost tla\u010d\u00edtek se paradoxn\u011b stala jejich nejv\u011bt\u0161\u00ed nev\u00fdhodou.<\/p>\n

Aby bylo testov\u00e1n\u00ed doopravdy objektivn\u00ed, doch\u00e1zelo k n\u011bmu za nejr\u016fzn\u011bj\u0161\u00edch klimatick\u00fdch podm\u00ednek a mezi testery pat\u0159ilo velk\u00e9 spektrum zrakov\u011b posti\u017een\u00fdch.<\/p>\n

Probl\u00e9m hlasitosti<\/strong><\/p>\n

P\u0159i odstra\u0148ov\u00e1n\u00ed bari\u00e9r se v\u017edy mus\u00ed myslet na pr\u00e1va v\u0161ech. Proto i v p\u0159\u00edpad\u011b ozvu\u010den\u00ed p\u0159echod\u016f nen\u00ed mo\u017eno myslet pouze na bezpe\u010dnost zrakov\u011b posti\u017een\u00fdch, ale i na kvalitu \u017eivota lid\u00ed v okol\u00ed \u017eij\u00edc\u00edch. Pokud by toti\u017e do\u0161lo k zes\u00edlen\u00ed akustick\u00e9ho ozvu\u010den\u00ed p\u0159echod\u016f, je pochopiteln\u00e9, \u017ee by se to nel\u00edbilo lidem v okoln\u00edch domech. Sou\u010dasn\u00e1 technologie um\u00ed alespo\u0148 to, \u017ee v noci nen\u00ed probl\u00e9m zvuk vypnout a nevidom\u00fd si ho zapne svou vys\u00edla\u010dkou pouze v p\u0159\u00edpad\u011b pot\u0159eby. To ale nov\u00e1 testovan\u00e1 technologie neumo\u017e\u0148uje. V praxi lze tedy \u0159\u00edci, \u017ee na m\u00e9n\u011b ru\u0161n\u00fdch m\u00edstech by si lid\u00e9 opr\u00e1vn\u011bn\u011b mohli st\u011b\u017eovat, \u017ee nemohou v noci sp\u00e1t.<\/p>\n

V dne\u0161n\u00ed technologick\u00e9 dob\u011b je a\u017e s podivem, \u017ee by p\u0159izp\u016fsobov\u00e1n\u00ed spr\u00e1vn\u00e9 hlasitosti ne\u0161lo n\u011bjak vy\u0159e\u0161it, probl\u00e9mem jsou ale pen\u00edze.<\/p>\n

„Je zde rovina technicko-ekonomick\u00e1. Technicky jist\u011b n\u011bco takov\u00e9ho ud\u011blat jde, n\u011bkdo by v\u0161ak musel zaplatit v\u00fdvoj, testov\u00e1n\u00ed, a v\u0161e dal\u0161\u00ed. Pokud je mi zn\u00e1mo, u n\u00e1s zat\u00edm nikdo nic takov\u00e9ho ned\u011blal,“ vysv\u011btluje Jan Urb\u00e1nek.<\/p>\n

Je velice pravd\u011bpodobn\u00e9, \u017ee i kdy\u017e nov\u00e1 technologie v n\u011bkter\u00fdch zem\u00edch Evropy byla nainstalov\u00e1na, u n\u00e1s se neosv\u011bd\u010dila a zrakov\u011b posti\u017een\u00ed se s n\u00ed nebudou setk\u00e1vat.<\/p>\n
