Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interaction with mobile terminals becomes complex due to the multitude of applications, requiring focused attention for switching between them, necessitating a simpler and more intuitive selection method for common applications.
Innovation Solution
A method and mobile communication terminal that allows users to easily switch between operational modes using a circular list, with visual, audible, and tactile indications, and animations, facilitated by a slide key that biases to a middle position for directional switching between predefined modes like phone, media player, and radio modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two dimensional menus are used to display multiple applications simultaneously, then the user can see a large number of selectable applications, but switching between applications still requires relatively focused attention and is not simplified
Solution Approach 1:
The patent segments the application switching process by introducing mode actuators that divide applications into distinct operational modes (e.g., phone mode, messaging mode, internet mode). Each mode actuator groups related applications together, allowing users to switch between mode groups quickly without navigating through all individual applications in a complex menu structure.
Solution Approach 2:
The patent adds a dimensional layer to application selection by introducing mode dimensions alongside application dimensions. Instead of a flat two-dimensional menu, the interface now has mode actuators as a third dimension, where users first select a mode (which filters or groups applications) and then select from the relevant applications within that mode, simplifying the overall selection process.
2Adaptability or versatility
If multiple applications and services are added to mobile terminals, then the functionality is enhanced, but user interaction becomes complex and difficult
Solution Approach 1:
The patent segments the diverse applications into organized mode groups (e.g., communication mode, entertainment mode, productivity mode). Each mode actuator manages a specific category of applications, allowing users to access functionality across multiple applications without being overwhelmed by the sheer number of options, thus maintaining simplicity despite enhanced versatility.
Solution Approach 2:
The mode actuators serve as universal access points that can trigger multiple applications within a mode. A single mode actuator press can initiate phone calls, send messages, or access contacts depending on the current context, providing multi-functional access through a simplified interface that doesn't require users to navigate complex menus for each individual application.

AI summary
It is presented a method for providing a user interface of a portable electronic apparatus. The method comprises: detecting an actuation of a mode switch actuator associated with switching operational modes of the apparatus; determining a switching direction by determining whether the actuation is associated with a first switching direction or a second switching direction; determining a current operational mode; determining a new operational mode considering the switching direction and the current operational mode; and switching operational modes of the portable electronic apparatus from the current operational mode to the new operational mode. Corresponding portable electronic apparatuses and computer program product are also presented.
