With the advent of the information age, the rapid development of computer software and hardware and related high-tech equipment has made today's interior design expression and display forms increasingly diversified, providing designers with a broad performance platform. On the basis of clarifying the ideas of the combined application of hand-drawn and computer graphics, we analyze the methods and approach of their combined application and expound on the actual application. It is hoped that the research can provide design ideas and references for the interior design industry and teaching activities. The Small Business Innovation Research (SBIR) program consists of three phases, the first of which is a feasibility study for the innovation. If the innovation is feasible, enter the second stage to finalize the innovative product, and after private and public sector investment, the third phase, commodity promotion and commercialization. The influence of intelligent equipment such as computers and hand-painted boards on the design industry is obvious. With the development of the social economy and the era of technological innovation, a social culture and a value system will be formed. Therefore, the arrival of media technology will also generate perceptions, ways of thinking, and value orientations and will affect our social interaction space, people's main living places, and indoor space. The software module in the computer provides designers with the opportunity to use computer design software to quickly present the designer's ideas on an electronic display screen. Its increasingly convenient design conditions promote the diversity and richness of design software. Combining intelligent multimedia images, with the help of compressed image noise reduction programming, SBIR technology, etc., it has created the development of an interior design. The number of students studying interior design has increased by nearly 60% every year, and the popularity of smart multimedia technology has also reached 78.9%. In the media age, people and interior designers are constantly changing their aesthetic tastes, narrative methods, expression methods, life function needs, and aspirations for a spiritual destination. Good interior design methods do not necessarily produce excellent interior design works, but good interior design works must be guaranteed by a set of practical design techniques and procedures. The article attempts to tap the multiple values of multimedia in indoor space to build a more humanized, humane, and media-inspired indoor space. [ABSTRACT FROM AUTHOR]
