Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing techniques for providing context-specific user interfaces on portable multifunction devices are cumbersome, inefficient, and consume excessive user time and device energy, particularly in battery-operated devices, due to complex interactions and unnecessary information display.

Innovation Solution

Implement methods and interfaces that efficiently switch and update user interface content based on temporal context changes, using user inputs to transition between applications and graphical depictions, and dynamically reflect or replace images to provide relevant information without redundant interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a widget displays sunset time information, then the user can access sunset time data, but the widget occupies screen real estate with irrelevant information for most of the day

Engineering Contradiction:

Improverelevant information availabilityVSAvoidscreen real estate

Core Design Contradiction:

Loss of informationVSArea of stationary object

Solution Approach 1:

The clock face is designed to dynamically change its displayed information based on temporal context. Different platters (display elements) are shown at different times of day, allowing the interface to adapt to the current time and display only relevant information. This resolves the contradiction by making the widget content dynamic rather than static, so screen real estate is efficiently utilized throughout the day.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the displayed parameter (information content) based on the time parameter. As time progresses, the clock face transitions between different platters that display different information relevant to different temporal contexts. This allows the same screen space to provide different useful information at different times, eliminating the waste of screen real estate.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If existing techniques provide context-specific user interfaces, then users can access relevant information, but the interface requires multiple key presses and complex interactions

Engineering Contradiction:

Improverelevant information accessVSAvoiduser interaction complexity

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The clock face interface automatically detects temporal context changes and switches between different platters without requiring user input. The system serves itself by monitoring time and autonomously updating the displayed information, eliminating the need for multiple key presses or complex user interactions to access context-specific information.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system prepares and displays relevant information in advance based on predicted temporal context. By anticipating what information will be needed at different times of day, the interface proactively displays the appropriate platter before the user needs to request it, reducing interaction complexity.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If the interface displays all available information continuously, then users have access to complete data, but device energy is wasted on displaying unnecessary information

Engineering Contradiction:

Improveinformation completenessVSAvoiddevice energy consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system extracts and displays only the subset of information that is currently relevant to the temporal context, rather than continuously displaying all available information. By taking out only the necessary platter for the current time period, the interface maintains information completeness for the relevant context while eliminating energy waste from displaying irrelevant data.

Inventive Principle:

Principle #2Taking out (Extraction)

4Loss of information

If existing techniques require multiple user interactions to access information, then users can access detailed data, but user time is excessively consumed

Engineering Contradiction:

Improveinformation accessibilityVSAvoiduser time consumption

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The interface automatically switches between platters based on temporal context without requiring user interactions. This self-service capability eliminates the time users would otherwise spend pressing keys or navigating through multiple screens to access context-specific information, while still providing complete information accessibility when needed.

Inventive Principle:

Principle #25Self-service

AI summary

Context-specific user interfaces, e.g., for use with a portable multifunction device, provide, inter alia, indications of time and, optionally, a variety of additional information. A user interface screen including a current time indicator and a first platter is displayed. The first platter is at a first position, is associated with a first application, and displays a first set of information obtained from the first application. The first set of information relates to a first temporal context of the current day. In response to detecting a user input, the first platter is displayed at a second position and a second platter is displayed at the first position. The second platter is associated with a second application and displays a second set of information obtained from the second application. The second set of information relates to a second temporal context of the current day.
