On keys' meanings and modes: the impact of different key solutions on children's efficiency using a mobile phone

The present study investigates the impact of different key solutions of mobile phones on users' effectiveness and efficiency using the devices. In the first experiment, 36 children (9 - 14 years) and in the second experiment 45 young adults (19 - 33 years) completed four common phone tasks twice consecutively on three simulated phones that had identical menus, but different key solutions. An approach was undertaken to quantify the complexity of keys in three models, incorporating different factors contributing to the keys' complexity (number of key options, number of modes and number of modes with a semantically dissimilar meaning), in order to predict users' performance decrements. As a further main factor, the degree of the users' locus of control (LOC) was measured and interactions with performance outcomes were studied. As dependent measures, the number of inefficient keystrokes, the number of tasks solved and the processing time were determined. Results showed a significant effect of control key solutions on users' efficiency and effectiveness for both children and young adults. Moreover, children's LOC values significantly interacted with performance: children with low LOC values showed the lowest performance and no learnability, especially when using keys with a high complexity. From the three factors contributing to the complexity of keys, keys exerting different functions with semantically inconsistent meanings had the worst effect on performance. It is concluded that in mobile user interface design keys with semantically inconsistent meanings should be generally avoided.

Effects of plant-based content,flavor and texture information on consumer satisfaction with non-fried ramen

The purpose of this study was to screen flavor information for positioning of non-fried ramen products and to examine the applicability of plant-based ingredient content in flavor communication. Effects of information related to savoriness, spiciness, menu name, plant-based ingredient content (%), and texture of samples on informed satisfaction were examined using home–use tests and online surveys. In order to form a regression model that explained variations in the informed satisfaction of non-fried ramen samples, we created indices that integrated the importance of information and the congruence of information with flavor perception. We have confirmed that effects of congruence on increasing satisfaction were higher than those of importance of information. When congruence/importance was used as an independent variable, a quadratic regression equation has explained the variations on satisfaction levels with an R² value of 72.7% (p = 0.006). Considering the positive congruence effect that plant-based ingredient percentages and perceived flavors had on informed satisfaction levels, communication schemes are needed to promote foods that have high percentages of plant-based ingredients.
