The following lists the content of the iPad user experience guide. For more details, referApple's Human Interface Guidelines for the iPad.
Supports interaction in all directions
Your App should be able to support users to operate iPad in any direction. Because users do not think that the iPad has a default direction, users do not care about the location of the iPad, and usually they do not know the correct location of the Home Key.
Enhance interaction gender patronizing and adding functions)
The best iPad application should allow users to interact with applications in a more novel way. Do not try to add irrelevant functions to the iPad. In particular, do not try to copy all applications on the iPhone to the iPad.
Reduce the level of your information
Although you do not want to accumulate too much information on a single page, you may worry that users need to find too many pages. The best way is to place important information in the main area of the screen and add additional information or tools, such as pover, to other areas.
Try to avoid full screen update
When some content on a screen is updated, try not to update the whole screen. It is best to change only the corresponding part. The fewer the number of full-screen updates, the more stable your App will be, and you will not be able to frequently find the location you saw last time.
Pay attention to program collaboration and connectivity
When designing a program, assume that the user is using your program to interact with others. In addition to physical device sharing, you can also consider virtual data sharing.
Increase the sense of presence and realism of the program
Add physical feedback to your program as much as possible to improve the realism of the program. The more real your program looks, the easier it is for users to understand your application and use it.
Enrich user experience with images
The resolution of the iPad screen is quite high, and various rich and beautiful pictures can be displayed. You can make full use of a variety of wonderful pictures to increase your preference for the application.
UI-oriented design
The well-designed UI can help users pay more attention to application content. Do not make the controls in the program too eye-catching. You can design your own controls to make them more in line with the overall style of the program. In this way, the control is not too eye-catching and easy for users to find.
Reduce Interaction
The iPad App should be able to support non-linear access. However, InterAction interrupts the continuity of user tasks and forces users to make choices.
Redesign your list
Consider the real scenarios of your App. For example, on the iPhone, the address book can only be a simple list. On the iPad, you can design the address book as a beautiful touchable address book.
Multi-contact gestures
Compared with the iPhone, the screen of the iPad is quite large and supports multi-touch gestures. Therefore, your application can consider how to handle gestures simultaneously operated by multiple users.
Consider using Popovers in a Modal task
If you use modal views in your iPhone App task, you can use popovers instead of modal views on your iPad.
Control the complexity of Modal tasks
Users usually prefer to run other subtasks under modal view. However, if the sub-tasks are too complex, the user may be confused about the application's focus.
Deprecated File Processing
Although the iPad App allows users to create and manage files on the iPad, or share files with the computer to connect the iPad to the computer), users should not feel the existence of the file system on the iPad.
Only remind the user to save as needed
Users' work should be stored on the iPad unless they delete or cancel the work. If your App is used to help users edit files, you need to ensure that their documents will not be lost even if the user does not explicitly choose to save the files.
Quick Start
The iPad App should be able to be started as soon as possible, so that users do not feel a significant delay after selecting the App.
Termination at any time
Like the App on the iPhone, When you select the Home key, the iPad App should be able to end immediately and enter a new App.
