*2.1. Domain-Specific Innovation (DSI)*

According to pertinent marketing research, consumer innovativeness, or the ability to use a new product more quickly than other consumers, is one of the most significant personality attributes influencing a consumer's decision to use or accept a new product [42,43]. According to the DSI structure, individuals who are consumer innovative in one category do not necessarily exhibit this behavior in other fields, which concentrates on aspects of human behavior related to innovation within a person's particular sphere of interest [44]. Thus, defined in the field of innovation performance more precisely forecasts the adoption of new products, leading to the development of innovation (domain-specific innovativeness) in specific areas, using innovative specific areas to forecast consumers' specific interest in the field of new products early adoption behavior and attitude [45]. Researchers worldwide have been adapting this model's structure to new fields and products in recent years [46–51]. However, many studies look at the product side of things, concentrating on the early degree of customers' adoption of new items while disregarding that some people only pay attention to the information about new products but do not necessarily buy them. Companies today need to pay closer attention to innovation centered on product details because of the dynamic nature of the business and technological landscapes and individual consumers' penchant for constant reinvention. Based on the two pillars of product and information, customer innovation in a given industry can be broken down into two categories: consumer information innovation and consumer product innovation [40].
