In this study we introduce logistic regression as a method for modeling, in this case the user’s detection rate, to more easily show cross-effecting factors, necessary in order to design an adaptive system. Previously such effects have been investigated by a variety of linear regression type methods but these are not well suited for developing adaptive systems. We investigate the method on a qualitative and quantitative dataset with ages spanning from seven to 79 years under indoor and outdoor experimental settings. The results show that the method is indeed a suitable candidate for quantification of, in this instance vibrotactile information, and for the future design of user adaptive vibrotactile displays. More generally the model shows potential for designing a variety of adaptive systems.

Lars Knudsen finished his studies at medialogy the summer 2011 where his master thesis concerned tactile displays and navigation, supervised by Hans Jørgen Andersen and Ann Morrison. Afterwards he has continued studying the field of tactile displays, especially with a focus on modeling modeling vibrotactile sensitivities.
