Hi, I'm Craig Will.

I do design and development for tablet and mobile phone applications, mostly iPads and iPhones.

See some of my papers below on both iOS programming and usability design for tablets:

See my book Understanding Swift Programming, available on Amazon as an E-book and in print, and also on Apple iBooks and Kobo.

Also see:

Understanding Optional Values in Swift. This paper describes how optional values are used to increase safety in Swift. The paper covers optionals basics, unwrapping, optional binding, implicitly unwrapped optionals, optional chaining, and multiple optional binding in Swift 1.2. PDF Version (10 pages)

What's Different About Swift. This paper describes in detail what is different about Apple's new programming language for iOS and Mac. It also discusses the claims made about Swift and assesses whether they are true. PDF Version (30 pages)

How to Get High Precision on a Tablet with a Drawing-Like App. This paper analyzes why drawing with a finger on a touchscreen is less precise than using a mouse on a PC. A method for drawing with a finger with high precision is suggested based on a virtual touch pad, and the application of the method is described for an app that draws maps for a tourism guide app. PDF Version (7 pages)

Engagement Styles: Beyond "Lean Forward" and "Lean Back". This paper challenges the idea, seen often today, that the tablet is necessarily a "lean forward" device, or that such an engagement style, as I call it, is necessarily linked to a particular device except by habit. This was published in March 2012 on the online design magazine Johnny Holland.

Here's a fun cartoon animation that shows a flying squirrel gliding and then landing on a tree. It's also very realistic--it's based on a real video of a flying squirrel coming in for a landing.
