  • ★★ How Long Does She Want You to Last? ★★ A recent study proved that the average man lasts just 2-5 minutes in bed (during intercourse). The study also showed that many women need at least 7-10 minutes of intercourse to reach "The Big O" - and, worse still... 30% of women never get there during intercourse. Clearly, most men are NOT fulfilling there women's needs in bed. Now, as I've said many times - how long you can last is no guarantee of being a GREAT LOVER. But, not being able to last 20, 30 minutes or more, is definitely a sign that you're not going to "set your woman's world on fire" between the sheets. Question is: "What can you do to last longer?" Well, one of the best recommendations I can give you today is to read THIS report. In it, you'll discover a detailed guide to an Ancient Taoist Thrusting Technique that can help any man to last much longer in bed. I can vouch 100% for the technique because my husband has been using it for years :) Here's the link to the report ■■■ https://tinyurl.com/rockhardxxx

Taustauuring

  1. 1. Taustauuring IFI6094.DT Kasutajakeskse disaini meetodid
  2. 2. (Leinonen, Toikkanen, & Silfvast, 2008)
  3. 3. Taustauuringu meetodid • Intervjuud • Kasutajate vaatlus • Kirjanduse analüüs • Konkurentsianalüüs
  4. 4. Cooper, A., Reimann, R., & Cronin, D. (2007). About Face 3: The Essentials of Interaction Design. Indianapolis, IN: Wiley Publishing, Inc.
  5. 5. Intervjuud
  6. 6. Juhised kasutajate intervjueerimiseks • Intervjuu peaks toimuma tüüpilises kasutuskohas • Väldi rangelt kindlaks määratud küsimusi • Pööra esmalt tähelepanu lõppeesmärgile, seejärel tegevustele • Ära tee kasutajast disainerit • Ära aruta tehnoloogilisi lahendusi • Väldi suunavaid küsimusi • Küsi lugusid, näiteid ja ringkäiku kasutuskohas • Suuna intervjuud vastavalt sellele, kuidas uued teemad esile kerkivad • Oska lugeda “ridade vahelt” (Cooper et al., 2007)
  7. 7. Küsimused eesmärkide kohta • Eesmärgid — Mis sõltub õnnestunud päev? Millest halb päev? • Võimalused — Millised tegevused kulutavad praegu liigselt Su aega? • Prioriteedid — Mis on Sulle kõige olulisem? • Informatsioon — Mis aitab Sul otsuseid langetada? (Cooper et al., 2007)
  8. 8. Küsimused süsteemi kohta • Funktsioon — Mis on peamised tegevused, mida Sa selle tootega teed? • Sagedus — Milliseid toote osasid Sa kõige enam kasutad? • Eelistused — Mis on selle toote lemmikküljed Sinu jaoks? Mis ajab Sind selle toote juures ärritab? • Probleemid — Kuidas Sa probleemide korral lahenduse leiad? • Kogemus — Milliseid klahvikombinatsioone Sa kasutad? (Cooper et al., 2007)
  9. 9. Küsimused tööprotsesside kohta • Protsess — Mida Sa tänase tööpäeva alguses esimesena tegid? Mida järgmisena? • Kordumised — Kui sageli Sa mingit tegevust teed? Millised tegevused korduvad iga nädal või kuu, kuid mitte iga päev? • Erandid — Milline on tüüpiline tööpäev? Milline oleks ootamatu sündmus? (Cooper et al., 2007)
  10. 10. Küsimused suhtumise kohta • Tulevikuplaanid — Mida Sa kujutad ennast tegemas viie aasta pärast? • Vältimine — Mida Sa eelistaksid mitte teha? Milliseid tegevusi Sa edasi lükkad? • Motivatsioon — Mida Sa naudid kõige enam oma töö (või elustiili) juures? Millised tegevused Sa kõigepealt käsile võtad? (Cooper et al., 2007)
  11. 11. Kasutajate vaatlus
  12. 12. Vaatluse kavandamine • Pane paika eesmärgid ja kogutava informatsiooni tüüp • Pane paika aeg, koht ja inimesed, keda vaadeldakse • Otsusta, kuidas vaatluse tulemusi talletada (Cooper et al., 2007)
  13. 13. Vaatluse läbiviimine • Tee kindlaks, et vaadeldavad on vaatluse toimumisest teadlikud • Vii läbi katsevaatlus • Ära häiri vaadeldavaid inimesi • Tee märkmeid ja täpsusta vajadusel hiljem • Kui võimalik, tee vaatluskohast foto • Kirjuta üles esmamuljed kohe pärast vaatlust (Cooper et al., 2007)
  14. 14. Kirjanduse analüüs
  15. 15. Kirjanduse analüüs • Äridokumentatsioon: turundusplaanid, turu-uuringud, kasutajate uuringud, kasutajatoe andmed • Tehnilised spetsifikatsioonid • Teadusartiklid • Teemakohased uudised meedias, tootearvustused • Teemakohased postitused ja arutelud sotsiaalmeedias (Cooper et al., 2007)
  16. 16. Konkurentsianalüüs
  17. 17. Brown, D. M. (2010). Communicating Design: Developing Web Site Documentation for Design and Planning. Berkeley, CA: New Riders. ptg
  18. 18. Põhjused konkurentsianalüüsi läbiviimiseks • Leida, kuidas teised on lahendanud sarnaseid disainiprobleeme • Hinnata kavandatud funktsionaalsusi lähedase rakenduse juures (Brown, 2010)
  19. 19. Juhised • Keskendu olulisele: ära võrdle korraga liiga palju süsteeme/ funktsionaalsusi/probleeme • Koosta võrdluse kriteeriumid • Vali võrdluse jaoks sobivad süsteemid (Brown, 2010)
  20. 20. Konkurentsianalüüsi ülesehitus • Lühikokkuvõte: eesmärgid, uurimisküsimused, kriteeriumid • Järeldused: üks leht/slaid järelduse kohta, koos ekraanipiltide fragmentidega • Võrreldud rakenduste profiilid (Brown, 2010)
  21. 21. Online Pet Store Competitive Review Version1 publishedJuly 31, 2010by Dan Brown(dan@eightshapes.com) 3 of 4 S r r u a Pet owners think about what they’re feeding their pets, sometimes even more than what they feed themselves. Displaying the ingredients right on the product page provides the information shoppers need to decide what food is right for their pet. Take-Aways List ingredients as part of the product description. If linked, incorporate“ingredients”as part of the label for the link or tab. Format as a list, rather than as a comma-delimited paragraph. Considerations Make individual ingredients linked to more information about it O er product comparisons so users can see how di erent foods compare in their ingredient lists Petsmart.com Petco.com DrsFosterSmith.com Je ersPet.com Comprehensive list of ingredients but“hidden”under Product Details tab. Formatting of list dense and di cult to read. Typography of ingredients list makes it easy to read. Requires scrolling down and clicking tab. Ingredients list behind“more information”tab. Finding ingredients requires scrolling. Essential data about food presented in nice table. (not shown) Ingredients list presented prominently on the page, adjacent to product image. (Brown, 2010)
  22. 22. Online Pet Store Competitive Review Version1 publishedJuly 31, 2010by Dan Brown(dan@eightshapes.com) 4 of 4 r m r u a Pet owners deliberate about some purchases for their pet, like food and dietary supplements, but other purchases (even large ones) may be more impulse, as an expression of appreciation.The product page needs to balance these two scenarios. What works Detailed product description Speci c product name Prominent calls to action Clear breadcrumb for easy hierarchy navigation What doesn’t Small product image Poor page layout Scrolling local navigation Take-aways Focus page on product description, not chrome Show large product images Align page navigation with product comparisons 1 2 3 4 5 6 7 1 2 3 4 5 6 7 (Brown, 2010)
  23. 23. Online Pet Store Competitive Review Version1 publishedJuly 31, 2010by Dan Brown(dan@eightshapes.com) 2 of 4 We compared 5 sites Across 20 criteria, including: mm r S r r What we did Conductedcompetitive reviewof other prominent pet supply web sites. Our objective Establishcommon practicesfor selling common pet supplies on the web. What worked ✓ Navigation categories based on pet type. ✓ Navigation categories with common supplies (like food and toys). ✓ Recommendations based on previous purchases. ✓ Home pages that highlighted new products, specials and the range of the catalog. ✓ Prominent calls to action taking users to the next step in the shopping process. What didn’t work ✗ Dense product pages: Squeezing all the information onto a single page with tabbed panels hides information that may help users make a purchase. ✗ One-size- ts-all product page: Users require di erent kinds of information about di erent product pages. ✗ Long lists of category links: User research shows that some products are clearly more important than others, and navigation should re ect that.

  24. 24. Beatport.com Release Page Beatport release page displays additional information that is important for dj’s. What works: • Track length and BPM are displayed on release page • Waveform and key are displayed on track details page • Release description • More releases from the same label What doesn’t work: • Release title is displayed in capital letters • Price is displayed without taxes Take-aways: • Display detailed metadata • Make metadata easy to copy • The system could recommend tracks with compatible key, tempo and style
