We are finally starting to think about how touchscreen devices really work, and design proper sized targets, think about touch as different from mouse selection, and to create common gesture libraries.
But despite this we still forget the user. Fingers and thumbs take up space, and cover the screen. Corners of screens have different accuracy than the center. It's time to re-evaluate what we think we know.
Steven reviews his ongoing research into how people actually interact with mobile devices, presents some new ideas on how we can design to avoid errors and take advantage of this new knowledge, and leaves you with 10 (relatively) simple steps to improve your touchscreen designs tomorrow.
You are dumb at the internet. You don't know what will go viral. We don't either. But we are slighter less dumber. So here's a bunch of stuff we learned that will help you be less dumb too.

The What If Technique presented by Motivate DesignMotivate Design
Why "What If"...?
The What If Technique tackles the challenge of engaging a creative, disruptive mindset when it comes to design thinking and crafting innovative user experiences.
Thinking disruptively is a disruptive thing to do, which means it's a very hard thing to do, especially when you add in risk-averse business leaders and company cultures, who hold on tight to psychological blocks, corporate lore, and excuse personas that stifle creativity and possibilities (see www.motivatedesign.com/what-if for more details).
The What If Technique offers key steps, tools and examples to help you achieve incremental changes that promote disruptive thinking, overcome barriers to creativity, and lead to big, innovative differences for business leaders, companies, and ultimately user experiences and products.
Let's find out what's what together! Explore your "What Ifs" with us. See www.motivatedesign.com/what-if for details about the What If Technique, studio workshops, the book, case studies and more downloads--including a the sample chapter "Corporate Lore and Blocks to Creativity"

Digital Strategy 101 is an overview of the current state of digital strategy and an exploration of core concepts, deliverables, and thought-leaders relevant to young practitioners.
Today we all live and work in the Internet Century, where technology is roiling the business landscape, and the pace of change is only accelerating.
In their new book How Google Works, Google Executive Chairman and ex-CEO Eric Schmidt and former SVP of Products Jonathan Rosenberg share the lessons they learned over the course of a decade running Google.
Covering topics including corporate culture, strategy, talent, decision-making, communication, innovation, and dealing with disruption, the authors illustrate management maxims with numerous insider anecdotes from Google’s history.
In an era when everything is speeding up, the best way for businesses to succeed is to attract smart-creative people and give them an environment where they can thrive at scale. How Google Works is a new book that explains how to do just that.

2. Služe za povećanje ili smanjenje
napona na potrošaču.
Za razliku od naizmeničnih, gde se
povećanje ili smanjenje napona može
jednostavno da se realizuje pomoću
transformatora, kod jednosmernog napona
to nije moguće. Najjednostavnije je to
uraditi razdelnikom napona ili
potenciometrom, ali se tako samo
smanjuje napona na potrošaču.
3. Zbog jednostavnosti transformisanja
naizmeničnog napona, jednosmerni napon
prvo pretvara u naizmenični, koji se
transformiše u veći ili manji, pa se zatim
vraća u jednosmerni.

4. S obzirom na to da li imaju u svom sastavu
transformator ili ne dele se na:
•Indirektne
•direktne
7. Za vreme dok je prekidač uključen, struja
prigušnice raste, a kada se prekidač isključi
struja prigušnice se zatvara kroz zamajnu diodu.
U ustaljenom stanju, srednja vrednost napona
na prigušnici je jednaka nuli. Ako je struja
prigušnice neprekidna, onda važi:
10. Ako se zamene mesta
diode i prekidača dobija
se čoper kao na slici.
Kod ovog čopera, struja prigušnice raste za vreme
dok je prekidač otvoren, a kada se prekidač zatvori
struja prigušnice se zatvara kroz diodu. U
ustaljenom stanju srednja vrednost napona na
prigušnici je jednaka nuli. Ako je struja prigušnice
neprekidna sledi:
14. •Popularan je jer sadrži samo jednu induktivnu komponentu
(jedno feritno jezgro) a ipak obezbeĎuje izolovan izlaz.
•Transformator u stvari nije pravi transformator, više se može
okarakterisati kao spregnuta prigušnica.
•Energija se prenosi tako što se prvo akumuliše u jezgru preko
primara, zatim se isprazni prema izlazu preko sekundara.
•Ovaj pretvarač se često koristi u prekidnom režimu.
•Kod drugih pretvraraèa sa transformatorom nagomilavanje
energije u transformatoru je minimalno, a ovde je naglasak na
tome.

16. Principijelna šema liči na
buck pretvarač samo se
naponski impulsi ne
dovode direktno na ulaz
LC filtra, već preko jednog
transformatora.

19. Potreban je jedan pomoćni
namotaj preko kojeg se u
svakoj periodi energija
magnećenja transformatora
vraća u izvor.

22. Pravougaoni impulsi za pobudu primara se dobijaju
preko prikazane dvotranzistorske veze. Tranzistori
se uključuju naizmenično, sa manjim ili većim
pauzama izmeĎu pojedinih uključivanja (zavisno od
željenog faktora ispune).

26. Pravougaoni impulsi za pobudu primara se dobijaju
preko mostne veze. Tranzistori se uključuju u
dijagonalnim parovima, sa manjim ili veãim pauzama
izmeĎu pojedinih uključivanja (zavisno od željenog
faktora ispune).
