“…The idea to adapt user interfaces to the emotional state of a user, however, also bears some risks. Paymans [31] discusses the usability tradeoffs regarding learnability in adaptive environments.…”

A lot of efforts have been directed to enriching human-computer interaction to make the user experience more pleasing or efficient. In this paper, we briefly present work in the fields of subliminal perception and affective computing, before we outline a new approach to add analog communication channels to the human-computer interaction experience. In this approach, in addition to symbolic predefined mappings of input to output, a subliminal feedback loop is used that provides feedback in evolutionary subliminal steps. In two studies involving concentration-intensive games, we investigated the impact of this approach. In a first study evolutionary feedback loops adjusted the user interface of a memory game whereas in the second study the lighting of the test room was adjusted dynamically. The results show that in settings with an evolutionary feedback loop test participants were able to reach significantly higher scores compared to the static counterparts. Finally, we discuss the impact that such subliminally working applications might have on the user's acceptance.

“…Based on these studies, Elliott et al (2002) made the conclusion that elements from models for usability can be incorporated to models of learnability as well. However, other researchers (e.g., Paymans, Lindenberg, & Neerincx, 2004) have noted that sometimes learnability and usability may be contradictory: that issues that improve learnability actually reduce usability. This is related to the question of how learnability and efficiency relate to each other, which I discussed earlier in this article.…”

In large ubiquitous computing environments it is hard for users to identify and activate the electronic services that match their needs. This user study compares the newly developed service matcher system with a conventional system for identifying and selecting appropriate services. The study addresses human factors issues such as usability, trust and service awareness. With the conventional system users have to browse a hierarchical list of currently available services and activate the service that they think satisfies their current needs. With the service matcher users just enter their current need using natural language, after which a wizard, emulating an existing service matcher algorithm, searches for and activates a matching service based on the given need and the users' location and gaze direction. This study shows that with the hierarchical list, only 66% of the tasks are solved correctly, and females score significantly worse than males. With the service matcher, the performance increases significantly to 84% correctly performed tasks and the gender difference disappears.
