Interaction Design Principles

As we get started on our design project, 0:00 here are a few principles that will be helpful to keep in mind. 0:03 Don't limit yourself to just these principles. 0:07 But this will get you to focus on a few things as you're making design decisions 0:09 about how to design the user experience and interface. 0:13 User should not have to wonder whether different word situations or 0:17 actions mean the same thing? 0:20 Therefore you should design interfaces to have similar operations and 0:23 use similar elements for achieving similar tasks. 0:27 For example, when you're designing a select function in an app, users should 0:30 use the same operation to select objects throughout the entire app or 0:34 make sure that the layout and interactions are consistent throughout. 0:38 Layout is important for creating meaningful and 0:43 useful experiences in a product. 0:46 As a person scans a page of information, they form an understanding 0:48 about what a product can do for them and what they can do using your services. 0:52 As a designer your goal is to help that learning process and 0:57 to motivate interaction. 1:01 The design should be thoughtfully organized with related features 1:03 content areas appropriately grouped, instead of forcing people to jump back and 1:06 forth around different areas to perform a single task. 1:11 In order to gain the confidence of your users, 1:15 you need to earn it by doing what you say you're going to do. 1:17 Setting people's expectations appropriately and following through. 1:21 One of the primary goals of experience design is to make things efficient for 1:25 people before making things efficient for the computer. 1:29 [SOUND] Efficiency allows for productivity and reduced effort and 1:32 a streamlined design allows more to get done in the same amount of time. 1:36 Creating efficiency demonstrates a great deal of respect for your customers. 1:41 And they'll be sure to notice. 1:46 We'll be revisiting these principles later as you being to design your mobile app and 1:48 start making design decisions. 1:52
