Immersive multimedia comprising metadata for five senses can provide user experience by stimulating memory and sensation. In the case of olfactory-enhanced multimedia, a computer-generated smell is combined with additional media content to create a richer and/or more realistic experience for the user. Although several studies have been conducted on olfactory-enhanced multimedia using e-nose and olfactory display, their practical applications have been severely restricted owing to the absence of a related standard. This paper proposes a method to standardize odor metadata obtained from an e-nose system, which has been particularly used to acquire data from different coffee aromas. Subsequently, the data were transferred to an odor display applicable for olfactory-enhanced multimedia using the ISO/IEC 23005 (MPEG-V) data template.

Realistic media comprised of metadata of the five senses to provide enhanced experiences by stimulating our memory and sensations have had an increasingly pervading effect in our daily lives. Many researchers and companies are in the process of developing their own authoring systems running on different platforms to serve realistic media, resulting in compatibility issues among the systems. To tackle these issues, the International Organization for Standardization have standardized the interface, data format, protocol, API, etc. required to provide the realistic media. In particular, the ISO/IEC 23005 standard, which is called MPEG-V in SC29/WG 11, has defined XML schemas for olfaction interaction based on electronic nose (E-Nose), and scent display. In this paper, the MPEG-V standard for olfaction interaction is reviewed, and a data flow diagram that can be used for olfactory interaction based on the MPEG-V standard was designed. In addition, the necessary schemas related to the E-Nose sensor for olfactory interaction was provided.

With the rapid spread of smart mobile products and practical use of wireless network, it became possible to offer the computing environment people can use anytime anywhere and it is predicted that portable computer as the next generation computing is to be put to practical use. This computer will be expected to have the new interface which provides realistic service through human's five senses as well as the interface through the visual and auditory senses. Accordingly, in this study, we are going to talk about the technology that expresses and reproduces what is based on olfactory information - closely related with memory among honan's five senses - in order to embody the lifelike user interface.

Will orange scent enhance video reality if it is presented with a video which vividly illustrates orange juice? Or, will romantic scent improve video reality if it is presented along with a date scene? Whereas the former is related to reality improvement when concrete objects or places are present in a video, the latter is related to a case when they are absent. This paper reviews previous research which tested diverse videos and scents in order to answer the above two different questions, and discusses implications, limitations, and future research directions. In particular, this paper focuses on measurement methods and results regarding acceptability of olfactory information, perception of scent similarity, olfactory vividness and video reality, matching between scent vs. color (or color temperature), and description of various scents using emotional adjectives. We expect this paper to help researchers or engineers who are interested in using scents for video reality.

This paper presents a capacity estimation of a storage system accumulating all data sensed during the lifetime of an individual human being. The calculation assumes modern data compression and data collection schemes based on wearable or implanted devices under ubiquitous environment. More than 76% of the storage area is found to be used for video data storage of common TV image quality. The remaining storage area is for data from other sensing organs including audio, taste, olfactory and tactual systems in addition to indexing information. Total storage area of around 600 tera bytes is needed to cover 100 years of human life including his fetal period.
