Adaptive User Interface for Environmental Control Based on Occupancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for office or home environments lack individualized control options, leading to discomfort and reduced energy efficiency due to not accounting for personal preferences, and their user interfaces are often overly complex.
Innovation Solution
A control device with a user interface that dynamically adjusts the range of control options based on presence information, allowing users to customize environmental properties like lighting, temperature, and air quality, while minimizing complexity by tailoring options to the number and location of occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are provided with extensive control options for environmental properties, then user comfort and personalization are improved, but user interface complexity increases
Solution Approach 1:
The user interface dynamically adapts the extent of control options based on presence information. When multiple users are detected, the system automatically adjusts which environmental properties can be controlled and what range of values are available, transforming a static complex interface into a dynamic one that simplifies itself based on contextual conditions.
Solution Approach 2:
Different levels of control granularity are provided to different users based on their presence and role. The system applies local quality by giving specific users access to specific control parameters (e.g., one user controls lighting while another controls temperature), rather than providing universal access to all parameters to all users.
2Ease of operation
If individualized control of environmental properties is enabled, then user comfort and satisfaction are improved, but energy consumption increases due to reduced automation
Solution Approach 1:
The system provides individualized control only to the extent necessary based on presence information. When users are present, appropriate control options are enabled; when absent, automation takes over. This partial action approach ensures personalization when needed while maintaining energy efficiency through automation when not needed.
Solution Approach 2:
The system continuously monitors presence information and uses this feedback to dynamically adjust the level of automation versus manual control. This feedback loop ensures that individualized control is activated only when users are present and need it, while automation remains active during absence to conserve energy.
3Ease of operation
If control options are simplified for ease of use, then user interface complexity is reduced, but adaptability to different user preferences decreases
Solution Approach 1:
The interface maintains simplicity as its default state but dynamically expands adaptability when presence information indicates users are present. The system transitions from a simple automated interface to a more personalized one based on real-time conditions, achieving both simplicity and adaptability at different times as needed.

AI summary
A control device (110) for controlling the environment in a region (102) within a structure (104) by means of controlling operation of a control system (120), which is adapted to adjust at least one property of the environment in the region (102), is disclosed. The control device comprises a user interface (112) adapted to selectively indicate to a user a range of available values representing at least one property of the environment in the region (102) that is adjustable by the control system (120) at least based on presence information of any persons being present within the region (102) such that the extent of control of the environment in the region (102) by means of the control device (120) that is thereby enabled the user is based at least partly on the presence information.
