Portable Device Calendar Interface Orientation View Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in designing user interfaces that allow easy interaction due to limited screen space, leading to complex key sequences and menu hierarchies, making it difficult for users to access and manage calendar functions intuitively.
Innovation Solution
A touch-sensitive portable multifunction device with a graphical user interface that adjusts calendar views based on device orientation, allowing users to switch between portrait and landscape modes to display events for different time periods, and includes features like multiweek calendars and gesture-based interactions for easy navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the screen size is reduced to make the device more compact, then the device becomes more portable, but the user interface becomes more difficult to interact with
Solution Approach 1:
The patent introduces orientation-based view switching, where rotating the device between portrait and landscape orientations changes the calendar display from a detailed daily view to a comprehensive multiweek view. This dimensional change (orientation) allows the interface to adapt to screen size constraints while maintaining usability.
Solution Approach 2:
The interface dynamically adjusts its behavior based on device orientation. The calendar application automatically switches between different time period displays (daily vs. multiweek) depending on whether the device is held in portrait or landscape mode, making the interaction model adaptive rather than static.
2Adaptability or versatility
If more functions are added to the device, then the device becomes more versatile, but the user interface becomes more complex
Solution Approach 1:
The device integrates multiple functions (calendar viewing, orientation sensing, gesture recognition) into a unified system. The same hardware components serve multiple purposes: the touch screen displays both calendar information and orientation indicators, while device rotation serves both as a physical orientation change and a trigger for view switching.
Solution Approach 2:
The calendar application automatically detects device orientation and switches views without user intervention. The system self-adjusts the display based on the detected orientation state, eliminating the need for manual view switching and reducing interface complexity.
3Loss of information
If the calendar view shows a longer time period, then more events are visible at once, but the detail level for individual events decreases
Solution Approach 1:
The calendar display dynamically adjusts its time period coverage based on device orientation. Landscape orientation triggers a multiweek view that shows broader event visibility, while portrait orientation provides a detailed daily view. This dynamic adjustment balances information visibility against detail level based on the available screen real estate.

AI summary
In accordance with some embodiments, a computer-implemented method is performed at a portable multifunction device with a touch screen display. The computer-implemented method includes displaying a multiweek calendar on the touch screen display, detecting a contact on an individual day in the multiweek calendar, and in response to detecting the contact on the individual day, displaying at least a portion of a list of events on the contacted individual day while continuing to display the multiweek calendar, wherein the list of events on the contacted individual day includes an invitation to an event.
