Mobile notification cues are not only the visual information on the user interface, but also the auditory and tactile information provided for the users. The purpose of this study was to explore the effects of visual, auditory, and tactile cues on mobile notification designs pertinent to users' situation awareness. The experiment was conducted using a 2x3 mixed factorial design to help investigate whether visual presentation type (i.e., dynamic and static) and different dimensions of cue combinations (i.e., visual (V), visual+sound (VS), and visual+vibration (VV)) affect users' task performance. Sixty participants were invited to take part in the experiment based on the convenience sampling method. The experimental data were collected through a time estimation and a questionnaire designed with a 7-point Likert scale. The generated results revealed that: (1) The different combinations of notification dimensions affect users' situational awareness and were reflected in the participant's subjective preferences and notification responses. (2) The notification of VS cues may significantly improve the participants' task efficiency compared with the vision cue alone. (3) When the notifications are the VV and VS cues, the dynamic presentation of visual cues would interfere with the users' recollection of the information. (4) VV cues could enhance the users' overall experience.
