Editor's Notes
- pretoze dizajn je o rieseni problemov. Ak problem neriesite, zrejme vytvarate dalsi … ako to casto vyzera v praxi
- Vsetko je to o rozhodnutiach
- pretoze bez dat …. Ako teda tie data ziskat Nechcem mot hovorit o tom, kde a ako tie data ziskavat, radsej vam to ukazem Case studies
- Truck, klient chcel moznost prepnut sa medzi aplikaciami
- Po analyze moznosti v ramci aplikacie, umiestnenie, hexagon – ine ako vsetky ostatne ikony v aplikacii, podobnost s prostredim klientovej aplikacie …
- Ego dizajner vo mne
- kolegovia, Google
- Moja oblubena metoda testovania ikon – zakryt popis rukou, prstom …
- spustali sme nativne verzie apky, chceli sme nove ikony, viac sucasne, menej detailov
- Chybal kontext
- tak sme ich vsadili do ich prirodzeneho prostredia, rovnake podmienky (nazov, cena, rating … vsetko), ale POZICIA
- a menili ich poradie
- Tu (pri vytvarani testu) som spravil jednu chybu, vidi ju niekto? Na jednu vec som zabudol. Click test “Nainstalujte si navigaciu” – nahodny vyber jednej z 5 variant Na konci kratky dotaznik …
- podla ocakavania, najviac klikov prave na ikony – tak funguje ludsky mozog. P Paid Search
- Stara vyhrala vo vo vsetkych variantach, na vsetkych poziciach, 3x tolko preklikov ako nova Nova bola druha najlepsia, dost dobre od kolegu Velmi tesne Waze na tretom mieste Na konci dotaznik, 90% uviedlo, ze ikony nepoznalo
- spustali sme nativne verzie apky, chceli sme nove ikony, viac sucasne, menej detailov
- stara mapa rozne miesta na mape podla kategorii
- Otvoreny card sorting – co to znamena
- Otvoreny card sorting – co to znamena
- Most of the sorts (48%) were very similar to this one, 12 groups 15 people achieves 90% correlation with the "complete" users group. 30 people correlates at 95%, 60 people at 98%. In our case the correlation is 97%. – Norman Nielsen Group research Moc vela kart, neodporucam, radsej tak 20 – 30 max, lebo to 100% completeness ratio je inak dost nizke
- Optimalsort
- Dendrogram (stromovy diagram)
- Similarity matrix (matica podobnosti)
- Cislo % ludi, ktori dali kartu do takej istej kategorie
- Jeden nechal otvorene okno dlho?
- Narastol vsak cas, takze sme este robili zmeny (Voices o level vyssie v menu)
- z 40% na 100%, takze z tohto pohladu uloha splnena on hlada voice ale my ho nutime vybrat si aky druh voicu chce, toto sme otocili podobne ako na prvej stranke vysledkov vyhladavania v Google dalsi mini test s ludmi, mobil do ruky, vyber voice, vsetci scrollovali podla abecedy, nikto neriesil vlajku Ziadne “ja si myslim” na meetingu, uz sme vedeli O dva dni uz na tom robil developer
- Uzasne, Uxakov sen, vzorka zrejme nebola dost velka
- 1. iba 2 zo 60 ludi ulohu nesplnili 2. menej backstepov 3. o 3 az 5 sekund menej 4. neoplati sa casovo a zlozitostou, maly benefit, ulohu aj tak vsetci splnili 5. 6. toto je viac menej zrejme z XY inych vyskumov, ale bolo dobre overit si to v praxi
- Vytlacite, ukazete timu
- A potom to vyzera nejako takto, v dalsej iteracii sa to opat zasadne zmeni. Toto su tiez data.
- Romanticke, zapad vpredu na displayi aj vzda v spataku viac UX bugov, serioznejsich ako tento
- problem velkych prerabok je v tom, ze su velke brainstorming sessions smer – focus groups Focus group (kvalitativny vyskum), nazeniete 4 az 8 ludi do jednej miestnosti a snazite sa konkretnymi napadmi riesit konkretne problem, na konci sumarizujete
- Ludia chcu lepit papieriky, maju pocit, ze rozhoduju, ze nieco ovplyvnuju, je to farebne, pekne, bavi ich to
- Nasytene focus groupy – no new ideas
- Sustredenie na Liptove na chate, uz sme mali data, nie len nazory
- niekolko iteracii prave testujeme, zbierame dalsie data
- videli sme niekolko prikladov, ako si zaobstarat data ako by to teda malo vyzerat
