Vehicle Mirror Display With Backseat Sound Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems fail to provide a sufficient sense of presence and entertainment property for users in moving objects, leading to suboptimal user experience and visibility, particularly in vehicles.
Innovation Solution
An information processing device and system that includes a display device and control unit to simulate a person or character in the backseat, synchronized with sound output from a speaker system, enhancing the sense of presence and entertainment by adjusting display and sound localization based on the vehicle's situation and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is used to show person images in a moving object, then entertainment property is improved, but sense of presence remains insufficient
Solution Approach 1:
The patent introduces a speaker system as an intermediary device to output sounds from multiple directions, creating a virtual sound source that corresponds to the displayed person image. This mediator enhances the sense of presence by providing auditory feedback that complements the visual display, making the entertainment experience more immersive and realistic.
Solution Approach 2:
The patent merges the display device and speaker system into an integrated information processing system. The control device coordinates both visual (display) and auditory (speaker) outputs to present person images with corresponding sounds, combining multiple sensory channels to simultaneously improve entertainment property and sense of presence.
2Reliability
If sound is output from all directions to enhance entertainment, then sense of presence is improved, but visibility and safety are reduced
Solution Approach 1:
The patent applies local quality by directing sound output to specific directions rather than uniformly from all directions. The control device determines appropriate sound output directions based on the displayed person image position, providing localized auditory information that enhances sense of presence without creating excessive ambient noise that would reduce visibility or distract the driver.
3Adaptability or versatility
If high quality service images are displayed continuously, then entertainment property is improved, but processing load increases
Solution Approach 1:
The patent implements periodic action by controlling the display device to update person images at appropriate intervals rather than continuously. The control device determines timing for image updates based on system state, maintaining high-quality entertainment display while reducing processing load by avoiding unnecessary continuous rendering and updates.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves the entertainment property and sense of presence for occupants, providing appropriate content quality based on vehicle conditions, reducing processing load, and enhancing user engagement.
Implementation Method 1
the first speaker outputs a sound by localizing a sound image so that the sound can be heard from the backseat to the occupant of the driver's seat or the front passenger seat
Implementation Method 2
a display device having a display configured to display a person image indicating a person or a character corresponding to the person and capable of adjusting a position of the display so that an occupant of a backseat is shown in a mirror
Data Source
AI summary
An information processing device mounted in a moving object includes a display device having a display display a person image indicating a person or a character corresponding to the person and capable of adjusting a position of the display so that an occupant of a backseat is shown in a mirror when an occupant of a driver's seat or a front passenger seat of the moving object visually recognizes the display on the assumption that the display is the mirror and the occupant is sitting in the backseat of the moving object and a control device control a first speaker within the moving object so that a sound is output from a direction of the backseat when the display is allowed to display a service image including the person image in which the person or the character is sitting in the backseat of the moving object.
