Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing haptic feedback systems fail to differentiate between notifications from multiple processing entities, leading to confusion for users as they cannot distinguish between haptic signals from different hosts.

Innovation Solution

An information processing device that identifies host types and converts haptic signals based on these identifications to differentiate notifications from multiple hosts, using a control unit to process haptic signals from multiple hosts into distinct signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If haptic feedback is provided from multiple hosts, then the quantity of notification information increases, but users cannot distinguish between notifications from different hosts

Engineering Contradiction:

Improvequantity of notification informationVSAvoidloss of host identification information

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent applies local quality by assigning distinct haptic signal characteristics (frequency, amplitude, waveform) to each host type. This allows each notification to carry local identifying features that enable users to distinguish the source host while receiving multiple notifications simultaneously.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses haptic signal characteristics as analogous to color changes - different hosts produce notifications with distinct frequency, amplitude, or waveform characteristics, allowing users to visually (or haptically) differentiate between notification sources similar to how different colors differentiate objects.

Inventive Principle:

Principle #32Color changes

2Device complexity

If haptic signals from multiple hosts are transmitted without differentiation, then device complexity is reduced, but user recognition of notification sources deteriorates

Engineering Contradiction:

Improvecomplexity of haptic signal processingVSAvoidease of recognizing notification sources

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent changes parameters of existing haptic signals (frequency, amplitude, waveform) based on host type identification. This approach maintains relatively simple device architecture while improving user recognition by modifying signal characteristics rather than introducing complex new processing systems.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If haptic signals are converted based on host type identification, then user recognition of notifications improves, but processing time increases

Engineering Contradiction:

Improveuser recognition of notificationsVSAvoidprocessing time for haptic signal conversion

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent performs host type identification and haptic signal parameter determination in advance, before the actual notification is transmitted. This preliminary action allows the conversion process to be optimized and cached, reducing the processing time required when notifications are actually delivered to users.

Inventive Principle:

Principle #10Preliminary action

AI summary

With the presence of a plurality of hosts taken into account, it is made easy for a user to recognize that notifications are from different hosts. Provided is an information processing device including a control unit that converts a haptic signal corresponding to notification information transmitted by each of a plurality of hosts into a different haptic signal on the basis of a determination result based on identification of host types of the plurality of hosts.
