Whereas there has been a huge interest in multimode calibration in the theoretical chemometrics literature, there are important limitations to the applicability of such techniques. Good, very high order, data are rare in analytical chemistry. Even three-way calibration, such as in DAD-HPLC, has to be used cautiously as there are frequent experimental difficulties with exact alignments of chromatograms in addition to interpretation of the numerical results. However, there have been some significant successes in areas such as sensory research and psychometrics. 

Overall, 104 respondents, mainly Europeans and North Americans, completed the survey. More than half were sensory professionals from industry (52%) with various levels of responsibihty other respondents were from sensory research and service institutes (27%) or from academia (21%). In Table 1.1 the three main limitations to the use of alternatives descriptive methods, namely lack of formalization, complexity of data analysis, and lack of trust and knowledge, are highlighted.

In research projects, especially in first stages of the project in order to gain faster sensory knowledge and make informed decisions in project management. This may apply to new product development (NPD) projects in R D as well as to sensory research projects.

The first example used to illustrate Napping was chosen for two main reasons. First, it will allow the reader to understand the intrinsic nature of the data collected when performing Napping, and the natural evolution from Napping to sorted Napping. Second, although the example is not directly related to sensory profiling, it is typical of the sensations sensory researchers are confronted with when they develop a new product, as it deals with emotions. 

In any ease, hopefully in the future, software paekages will be developed to help even the non teeh-savvy sensory researcher to extract valuable information from open-ended questions (and if the task is recorded orally, why not also transcribe it accurately) without missing the meaning of the expressions. Unfortunately, this idea is currently utopian, but there are fast advances being made in the area of computer intelligence regarding text and data mining, so time will tell. 

Mobile sensory research a new mobile research method... 

But as for any other trend, there are not only pros but also cons to mobile sensory research. The development of an own-research app is first of all connected to high costs. Like aU innovations in their early adoption phases, apps too require new competencies. Since the knowledge on how to implement new technologies is mostly non-existent in the early phase, services need to be bought in either as individual or off-the-shelf solutions. This saves costs but reduces freedom and independence in-home solutions secure independence but are mostly rather time and cost intensive. Mobile research has further critical limitations, such as limitations on the number of... 

Taking all previously gathered information into consideration, we conclude that mobile research delivers benefits additional to those of traditional sensory research, such as high external and ecological validity as well as rapid data delivery (see Table 21.1). That is why we believe it to be worth being considered as new approach in the sensory community. 

Since, especially for consumer journeys, it is important to measure product liking at the right place and time, we have chosen the consumer journey of a body care product as case study because it nicely offers the opportunity to assess the strengths and weaknesses of mobile sensory research.
