Touch Sensitive Display Restricted Mode Multi-Point Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices in restricted mode cannot easily access information without exiting the restricted mode, which can be inconvenient and may require transitioning to an active mode, consuming more power.
Innovation Solution
A touch-sensitive display and controller configuration that detects user inputs, such as multi-point or trace inputs, to present information without exiting the restricted mode, allowing users to access information without powering up the device fully.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the apparatus is in restricted mode of operation to prevent unintentional function activation, then energy consumption is reduced, but user access to information becomes difficult
Solution Approach 1:
The patent segments user input interactions into different types: standard single-point touches that activate functions, versus multi-point simultaneous touches that trigger information display without exiting restricted mode. This segmentation allows the system to provide information access while maintaining energy-saving restricted mode, resolving the contradiction between ease of operation and energy consumption.
2Ease of operation
If the user exits restricted mode to access information, then full functionality is available, but power consumption increases
Solution Approach 1:
Instead of requiring the user to completely exit restricted mode (excessive action) to access information, the patent enables partial action through multi-point touch inputs that trigger information display while remaining in restricted mode. This partial action approach provides sufficient information access without the full power consumption penalty of exiting restricted mode.

AI summary
An apparatus, method, computer program and user interface wherein the apparatus includes a touch sensitive display; and a controller; wherein the apparatus has a restricted mode of operation in which user access to at least some functions of the apparatus is prevented and the touch sensitive display is configured to detect a user input while the apparatus is in the restricted mode of operation wherein the user input comprises actuation of a plurality of points of the touch sensitive display; and the controller is configured, in response to the detection of the user input including actuation of a plurality of points of the touch sensitive display, to control the apparatus to present information without exiting the restricted mode of operation of the apparatus.
