Calendar Interface with Pop-up Preview for One-Handed Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld portable electronic devices face challenges in providing an intuitive and user-friendly interface for managing and viewing calendar data, particularly in scheduling meetings and accessing planners on-the-go, as current systems often require two hands and are not easily navigable with one hand.
Innovation Solution
A method for graphically managing and manipulating calendar data using a five-way navigation button, allowing users to navigate through weekly and monthly views, with pop-up previews and color-coded categories, enabling one-hand operation and intuitive data manipulation on devices with touch-screen displays or rectangular screens that can expand to provide extended viewing areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a graphical user interface is used for managing calendar data on handheld devices, then data manipulation capability is improved, but ease of operation deteriorates because it requires two hands and a convenient lap or desk
Solution Approach 1:
The interface is segmented into functional zones: a display area for calendar data and a separate input area with physical buttons. This allows the display to show detailed information while the buttons provide tactile feedback for one-handed operation, resolving the contradiction between graphical capability and ease of use.
Solution Approach 2:
Physical buttons serve as an intermediary between the user and the graphical interface. These buttons provide tactile feedback and can be operated with one hand, mediating between the limitation of handheld operation and the need for graphical data manipulation.
2Loss of information
If more calendar data is displayed on the screen, then information visibility is improved, but device complexity increases due to space constraints on handheld devices
Solution Approach 1:
The interface uses multiple dimensions to display information: the display screen shows calendar data visually, while the button states (pressed/unpressed) provide additional information feedback. This multi-dimensional approach allows comprehensive information display without increasing physical device complexity.
Solution Approach 2:
The interface uses visual differentiation (color coding or highlighting) to indicate selected items and their associated data. This allows multiple pieces of information to be displayed simultaneously with clear visual hierarchy, improving information visibility without requiring more physical space.
3Ease of operation
If a five-way navigation button is used for input, then ease of operation is improved for one-hand use, but device complexity increases
Solution Approach 1:
The five-way navigation button serves multiple functions: directional navigation, selection, and triggering actions. This multi-functional design provides one-handed operation capability without requiring separate buttons for each function, thus not significantly increasing device complexity.
Solution Approach 2:
Multiple input functions (directional control, selection, action triggering) are merged into a single five-way navigation button. This consolidation provides comprehensive one-handed operation capability while minimizing the increase in device complexity.

AI summary
Embodiments of the present invention relate to methods and devices for graphically managing and manipulating calendar data in a database, in a weekly view and in a monthly view. In either mode, a highlighted element is selected thereby causing a preview window to pop-up to display appointment details. The preview window and the image of the week or the month are displayed simultaneously.
