Portable Content Handoff Using ID Transfer for One-Touch Viewing

Solution Overview

Problem

Existing technologies require multiple operation steps to seamlessly transfer the viewing of content from a portable terminal to a larger information processing apparatus, such as a television set, leading to increased user interaction.

Innovation Solution

A portable terminal equipped with a receiving unit, external device communication unit, display unit, acquiring unit, and control unit that allows for the transmission of identification information to an external information device, enabling smooth transfer of content viewing without manual termination and resumption on both devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If content viewing is transferred from portable terminal to information processing apparatus, then viewing can be continued on larger display, but multiple operation steps are required increasing user interaction

Engineering Contradiction:

Improvedisplay areaVSAvoiduser interaction

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The portable terminal acquires identification information about the content being viewed and transmits it to the information processing apparatus in advance. The apparatus prepares to display the same content automatically, so when the user activates the transfer function, the content is already ready for seamless continuation without requiring manual resumption operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically handles the content transfer process without requiring extensive user intervention. The portable terminal and information processing apparatus exchange identification information and automatically resume content display on the larger device, reducing the burden on the user to manually manage the switching process.

Inventive Principle:

Principle #25Self-service

2Area of stationary object

If content viewing is transferred from portable terminal to information processing apparatus, then viewing can be continued on larger display, but manual termination and resumption operations are required

Engineering Contradiction:

Improvedisplay areaVSAvoidoperation steps

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The portable terminal acquires identification information about the content being viewed and transmits it to the information processing apparatus in advance. The apparatus prepares to display the same content automatically, so when the user activates the transfer function, the content is already ready for seamless continuation without requiring manual resumption operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses identification information as feedback about the current viewing state to automatically control the content transfer. The portable terminal provides feedback through identification information, and the information processing apparatus uses this feedback to automatically resume the correct content without requiring the user to manually terminate and restart.

Inventive Principle:

Principle #23Feedback

3Area of stationary object

If multiple operation steps are used for content transfer, then content can be displayed on larger screen, but user interaction time increases

Engineering Contradiction:

Improvedisplay areaVSAvoiduser interaction time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The portable terminal acquires identification information about the content being viewed and transmits it to the information processing apparatus in advance. The apparatus prepares to display the same content automatically, so when the user activates the transfer function, the content is already ready for seamless continuation without requiring manual resumption operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The content viewing action continues uninterrupted from the portable terminal to the information processing apparatus. By transmitting identification information and automatically preparing the content for display, the system maintains continuous viewing without requiring the user to terminate on one device and restart on another, thus eliminating time loss.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A portable terminal includes a receiving unit which receives content information, an external device communication unit which conducts communication with an external information device, a display unit which displays the content information received by the receiving unit, an acquiring unit which acquires identification information identifying the content information displayed by the display unit, an operation unit which receives an operation indication from a user, and a control unit which conducts control such that if a transmission indication of the identification information is received by the operation unit while the content information is being displayed, the identification information acquired by the acquiring unit is transmitted to the external information device and the display of the content information by the display unit is terminated.
