AbstractWe have been talking about IoT (Internet of Things) or UbiComp (Ubiquitous Computing) for several years. It is often regarded as a central point that the information and communication technology leaves the workplace and enters the home. The smart fridge has often been considered as a prototypical example of application of the IoT for the home. There are many studies on smart home service and smart home appliances, but very little research has been conducted on both the consumer characteristics and product features. Some real smart home appliances had already been put into the market including smart fridges. But most of the early products did not turn out to be a big success. As a part of the UbiComp, smart devices, which include smart phone, tablet PC, PDA, navigation, etc., are recently been more and more popular than years ago. Consumers’ acceptance of new smart devices could be affected by the prior experience of using smart devices. However, very little research has conducted on users’ acceptance of smart home appliances using the Smart Device Using Experience (SDUE) as a new factor. We chose smart fridge to study the factors which affect users’ acceptance, focusing on both the consumer characteristics and product features. We used a function-list of the smart fridge as a scenario, in which each function was collected from the prior research and the latest prototype products shown on exhibitions like CES (Consumer Electronics Show).Several years ago, since people were even not very much familiar with smart phones, a smart fridge could be too complicated for most of them to handle. But with the spread of various kinds of smart devices, people developed new using patterns and new attitude towards them. Manufacturers who customized their products in consideration of user’s prior experience of using similar products seem to perform better than others who did not.To understand the acceptance of smart fridge, a questionnaire was designed to examine how Korean female consumers perceive smart fridge for domestic setting.Findings of this research show that consumers are becoming more and more interested in smart fridge, and consumers who have never used a real smart fridge before but have a certain level of using other smart devices like smart phones are likely feel more confident when using smart fridges. Also, if the user interface of a smart fridge is similar to other smart devices that people used before, will make people feel more confident when using it. Because the smart fridge is still in its development phase, people do not have a whole understanding of how much convenience the smart fridge will provide nor will it be too much complicated. According to the result of this research, perceived ease of use did not have a direct effect on the behavioral intention. Perceived risk has a negative effect on both behavioral intention and perceived ease of use. But in this research, the result did not show a direct relation between perceived risk and perceived usefulness. The context awareness function of the smart fridge made people feel that it will be easy to use a smart fridge with such functions, and that it will be useful. Ubiquitous connectivity, which is a key feature of ubiquitous computing, did not make people feel easy to use, although consumers do think that it is useful.
