Abstract : Salience has generally been regarded as a property of a stimulus that allows it to stand out and be noticed. Typically, tactile stimuli are defined by dimensions such as the frequency, intensity, force, location, and duration of the signal. However, these definitions and their associated thresholds, in isolation, are of little value if one does not consider interaction characteristics of the user or situational context. In this report we describe a preliminary model for tactile salience composed of 3 core constructs (individual differences, technology, and context) and their interactions. This definition provides an integrated approach to assess effectiveness of tactile displays. We report an initial series of comparative tests using paired comparisons with forced-choice and independent scaled ratings of various multitactor patterns. Results showed significant differences due to tactor design characteristics, patterns of tactile cue arrays, and some differences due to measurement approach. Implications for future research are discussed.
