Due to the complexity of colour perception and comprehension and its importance in contemporary life, there is an increasing need to understand the emotions which appear as our response to the observation of colour or coloured object. In the present research, the emotional response to colour was studied in a test group of Slovene female observers who were divided into four groups according to their age. The analysis was performed based on a questionnaire which included 21 colour samples of seven basic hues and diff erent lightness and/or saturation. The observers were asked to arrange the colours according to fi ve distinct pairs of characteristics: active-passive, like-dislike, warm-cold, stimulating-calm, modern-classical. The results showed that considerable diff erences exist regarding colour emotions, i.e. the emotional response to colour. The most pronounced contrasts between the women of diff erent age were found with respect to the attribute pair like-dislike. In most cases women preferred colours that were recognized as active; these colours were mostly saturated and very intense. However, the ranking and selection of the most popular colours were diff erent across age groups. In the group of female observers aged between 31 and 50 years, saturated colours were found to be less popular. The diff erences in the emotional experience were also observed with other attributes such as stimulating-calm and warm-cold. Regardless of the age, black was found to be a special case since it was described as a passive colour by the majority of women, in spite of being very popular.
Applications presenting the content of a specific professional field are more frequently used for educational purposes. Not only that the interactive solutions including multimedia can more effectively transfer knowledge due to their property to offer a content on a demand, but they are also very attractive, they augment user experience, are able to present more spatial and time dependent data and they usually involve multisensory approaches including senses of vision, hearing and touching. In the research the work frame and a design process of the educative app solution for geological purposes is presented. The aim of the app is to interactively determine stones by means to implement geological stone key. The experimental part presents the strategy phase, in which the target groups were defined, their needs were analysed and touching points for the successful networking, sharing and promotion were introduced. Next, app's functionalities and content types were created, based on the specification of professional field of geology. The content was categorised and labelled so that in the context of the whole app's structure required hierarchy and organisation of the content categories were introduced. User interface design began with simple layout sketches and with iterative approach that followed, more interactive prototypes were designed, developed and tested using the wireframes. In the results the final prototype and its design are presented with the evaluation of user-centred design approach that was implemented in the work frame.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
