Solution Overview

Problem

Conventional information handling systems require users to manually select and manage input and output devices, leading to suboptimal interactions due to changing contexts and underutilization of available resources, resulting in a degraded user experience.

Innovation Solution

An immersed information handling system environment that coordinates input and output devices to adapt to the user's context and processing needs, using projected user interfaces, capacitive sensors, and cameras to track interactions in a common coordinate system, automatically selecting peripherals and managing resources for efficient and natural user interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually select and manage input and output devices, then users have control over device selection, but user experience is degraded due to changing contexts and increased complexity

Engineering Contradiction:
Improveuser interaction simplicityVSAvoidI/O device management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically selects and manages input and output devices based on detected user context, eliminating the need for manual device selection. The contextual awareness module continuously monitors user state and environment to autonomously determine optimal I/O device configuration, allowing users to focus on tasks rather than device management.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures I/O device selections based on predicted user needs derived from contextual analysis. By anticipating user requirements before explicit selection is needed, the system proactively establishes optimal device configurations, reducing the cognitive load and complexity of device management.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple peripheral devices are made available, then device versatility is improved, but selection complexity increases for end users

Engineering Contradiction:
Improveperipheral device availabilityVSAvoidperipheral selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The contextual awareness module continuously monitors user context and provides feedback to the device selection mechanism. This closed-loop system adapts device selections based on real-time user state, environment, and task requirements, making the system respond dynamically to changing conditions without requiring user input.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system implements a unified device management architecture that handles multiple peripheral types through a common framework. The contextual awareness module serves as a universal interface that understands various input and output devices, enabling versatile device selection without increasing user complexity through standardized contextual parameters.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If I/O devices work independently based on user election, then device independence is maintained, but resource underutilization occurs

Engineering Contradiction:
Improvedevice independenceVSAvoidresource utilization efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The system merges the independence of individual I/O devices with coordinated resource management through a centralized contextual awareness module. Each device maintains its operational independence while the module synthesizes device availability and user context to optimize overall resource allocation, preventing underutilization through holistic device management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically adjusts device coordination based on changing user context and resource availability. The contextual awareness module continuously updates device selection and resource allocation in response to real-time conditions, enabling the system to adapt from static independent operation to dynamic coordinated resource utilization.

Inventive Principle:
Principle #15Dynamics

AI summary

Identifying characteristics integrated in a totem and detected by a capacitive display mat are applied to perform functions in response to end user inputs. Identifying characteristics include capacitive feet integrated in a totem bottom surface with identifying features including varying capacitive values for the feet, varying pad sizes and shapes, varying pad patterns and varying capacitive oscillation frequencies. In one embodiment, the surface area of the totem in contact with the capacitive mat varies depending upon the pressure placed on the totem to alter the shape of a compressible material disposed at the bottom surface.
