Solution Overview

Problem

Existing electronic devices often display user interfaces in two dimensions, which can reveal personal or private information about the user to applications by allowing them to position UIs at any location and orientation, compromising user privacy.

Innovation Solution

Implementing system-defined, discrete, three-dimensional distance layers for user interface positioning, where applications can request specific layers semantically labeled by the system, and users can adjust these layers while applications are restricted from modifying them.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If applications are allowed to position user interfaces at any location and orientation, then user interface flexibility and adaptability are improved, but user privacy is compromised as applications can derive personal information from UI positioning

Engineering Contradiction:

Improveuser interface positioning flexibilityVSAvoiduser privacy compromise

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the three-dimensional space into discrete volumetric layers (e.g., first volumetric layer, second volumetric layer, third volumetric layer) at different distances from the display device. Each layer is semantically labeled and applications can only position user interfaces within these predefined layers, preventing arbitrary positioning that would reveal user privacy information while maintaining interface flexibility within the constrained structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces volumetric layers as an intermediary structure between the display device and applications. These layers act as mediators that applications must use for positioning user interfaces, rather than allowing direct arbitrary positioning. The layers provide a structured intermediate framework that preserves privacy by limiting positioning freedom while still enabling flexible interface design within the constrained volumetric spaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If system-defined discrete volumetric layers are implemented for user interface positioning, then user privacy is protected by preventing arbitrary UI positioning, but device complexity increases due to the layered structure and semantic labeling system

Engineering Contradiction:

Improveuser privacy protectionVSAvoidvolumetric layer structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The volumetric layers serve multiple functions simultaneously: they provide privacy protection by constraining UI positioning, enable spatial awareness by creating distinct volumetric zones, support accessibility through structured layer organization, and maintain flexibility within constraints. This multi-functionality reduces the need for separate mechanisms for each purpose, thereby managing complexity while achieving comprehensive privacy protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter space from continuous arbitrary positioning to discrete volumetric layer selection. By transforming the positioning parameter from any possible 3D coordinate to a有限 set of predefined volumetric layers with semantic labels, the system achieves privacy protection through parameter discretization while managing complexity through a finite, manageable parameter space.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If applications can request specific semantically labeled volumetric layers, then user interface placement precision and user control are improved, but the ease of operation decreases as users must manually adjust layer configurations

Engineering Contradiction:

Improveuser interface placement precisionVSAvoiduser layer adjustment ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The volumetric layers are pre-configured with semantic labels and predefined spatial characteristics before use. Applications can request specific layers without requiring users to perform complex configuration tasks. The preliminary structuring of the volumetric space into meaningful layers enables precise placement while reducing operational complexity through pre-established conventions and labels that users can intuitively understand and select from.

AI summary

Aspects of the subject technology provide volumetric interface layers for an electronic device. The volumetric interface layers may be discrete distance layers, each having a respective distance from the electronic device, in which user interfaces can be displayed by the electronic device. Applications running on the electronic device may be provided with the ability to request display of a user interface for the application in one of the discrete distance layers. In one or more implementations, the discrete distance layers may be semantically labeled, and may be requested by an application using their semantic labels.
