Designing residential interiors strongly impacts occupant satisfaction but remains challenging due to unstructured spatial layouts, high computational demands, and reliance on expert knowledge. Existing methods based on optimization or deep learning are either computationally expensive or constrained by data scarcity. Reinforcement learning (RL) approaches often limit furniture placement to discrete positions and fail to incorporate design principles adequately. We propose OID-PPO, a novel RL framework for Optimal Interior Design using Proximal Policy Optimization, which integrates expert-defined functional and visual guidelines into a structured reward function. OID-PPO utilizes a diagonal Gaussian policy for continuous and flexible furniture placement, effectively exploring latent environmental dynamics under partial observability. Experiments conducted across diverse room shapes and furniture configurations demonstrate that OID-PPO significantly outperforms state-of-the-art methods in terms of layout quality and computational efficiency. Ablation studies further demonstrate the impact of structured guideline integration and reveal the distinct contributions of individual design constraints.

Interior design is a complex and creative discipline involving aesthetics, functionality, ergonomics, and materials science. Effective solutions must meet diverse requirements, typically producing multiple deliverables such as renderings and design drawings from various perspectives. Consequently, interior design processes are often inefficient and demand significant creativity. With advances in machine learning, generative models have emerged as a promising means of improving efficiency by creating designs from text descriptions or sketches. However, few generative works focus on interior design, leading to substantial discrepancies between outputs and practical needs, such as differences in size, spatial scope, and the lack of controllable generation quality. To address these challenges, we propose DiffDesign, a controllable diffusion model with meta priors for efficient interior design generation. Specifically, we utilize the generative priors of a 2D diffusion model pre-trained on a large image dataset as our rendering backbone. We further guide the denoising process by disentangling cross-attention control over design attributes, such as appearance, pose, and size, and introduce an optimal transfer-based alignment module to enforce view consistency. Simultaneously, we construct an interior design-specific dataset, DesignHelper, consisting of over 400 solutions across more than 15 spatial types and 15 design styles. This dataset helps fine-tune DiffDesign. Extensive experiments conducted on various benchmark datasets demonstrate the effectiveness and robustness of DiffDesign.

Interior design is all about creating spaces that look and feel good. However, the subjective nature of aesthetic preferences presents a significant challenge in defining and quantifying what makes an interior design visually appealing. The current paper addresses this gap by introducing a novel methodology for quantifying and predicting aesthetic preferences in interior design. Our study combines fuzzy logic with image processing techniques. We collected a dataset of interior design images from social media platforms, focusing on essential visual attributes such as color harmony, lightness, and complexity. We integrate these features using weighted average to compute a general aesthetic score. Our approach considers individual color preferences in calculating the overall aesthetic preference. We initially gather user ratings for primary colors like red, brown, and others to understand their preferences. Then, we use the pixel count of the top five dominant colors in the image to get the color scheme preference. The color scheme preference and the aesthetic score are then passed as inputs to the fuzzy inference system to calculate an overall preference score. This score represents a comprehensive measure of the user's preference for a particular interior design, considering their color choices and general aesthetic appeal. We used the 2AFC (Two-Alternative Forced Choice) method to validate our methodology, achieving a notable hit rate of 0.7. This study can help designers and professionals better understand and meet people's interior design preferences, especially in a world that relies heavily on digital media.

Harmony level prediction is receiving increasing attention nowadays. Color plays a crucial role in affecting human aesthetic responses. In this paper, we explore color harmony using a fuzzy-based color model and address the question of its universality. For our experiments, we utilize a dataset containing attractive images from five different domains: fashion, art, nature, interior design, and brand logos. We aim to identify harmony patterns and dominant color palettes within these images using a fuzzy approach. It is well-suited for this task because it can handle the inherent subjectivity and contextual variability associated with aesthetics and color harmony evaluation. Our experimental results suggest that color harmony is largely universal. Additionally, our findings reveal that color harmony is not solely influenced by hue relationships on the color wheel but also by the saturation and intensity of colors. In palettes with high harmony levels, we observed a prevalent adherence to color wheel principles while maintaining moderate levels of saturation and intensity. These findings contribute to ongoing research on color harmony and its underlying principles, offering valuable insights for designers, artists, and researchers in the field of aesthetics.

Architects and interior designers have switched from pencils and papers to digital software and iPads, causing a significant change in design practices over the last few decades. Digital tools, as well as VR and AR technologies, are changing the way we learn, work, and live. And a whole new direction of parametric design, which is native to the digital world, has appeared. Planner 5D – a 3D home design platform that enables anyone to create floor plans and interior designs with the help of AI – has announced the launch of the Data-Driven Interior Design Program to partner and collaborate with educational institutions, universities, and dedicated researchers. Planner 5D currently helps more than 70 million users who have created over 300 million projects improving their living or working spaces, renovating their homes, and changing the look and feel of places they belong to.

There's a concept in artificial intelligence called "the singularity." It refers to the idea that AI will one day be able to reproduce and improve upon itself at increasingly rapid speeds, resulting in a computerized brain exponentially more powerful than human intelligence, capable of transforming civilization as we know it. Some scholars are confident the singularity is only a matter of time. Others say it's pure science fiction. For the time being, let's leave the issue to the Ph.D.s and focus on a few simpler questions.

What does interior design have in common with AI art? If you think it is a tricky question and you are tempted to say absolutely nothing, well, stop for a moment because the answer is instead quite simple: they both have an impact on the space where people live in and therefore on people lives. The psychology of space is at the heart of many businesses along with a strong vision of bringing creativity into a project that must show also a distinctive stamp [1]. Creating a project for a commercial area is different that working on one for hospitality or a hospital. The crucial aspect is to tune in with the client and have a solid vision, making a space that is enjoyable and where people want to spend time in and go back to.

The driver's seat may be on the left side, but it has long rested at the center of the way cars are designed. The basic interior setup derives from that of the horse-drawn carriage, with ready access to acceleration, steering, and braking systems, 360-degree visibility, and the necessary sightlines over the power source in front. The forces reshaping the nature of transportation are conspiring to shift that focus away from the driver--first toward the rear row, and eventually toward a kind of vehicle that defies conventions like front and back seats. As traffic increases and commute times extend, consumers with money to spend (especially in China) are hiring chauffeurs and retiring to the back seat. Look, for example, at the introduction into the American market of long-wheelbase, rear-seat biased vehicles like the BMW 5-Series GranTurismo or the Volvo S60 Inscription, originally developed for Chinese buyers. The booming ridehailing industry brings the same backseat luxury to the masses, and so automakers are creating vehicles with users other than the driver in mind.
