Designing Effective Vibration Patterns for Tactile Interfaces
Tactile interfaces presenting vibration stimuli are able to communicate confidentially and silently. Recent advances have enabled the users of mobile devices to create their own vibration patterns using software installed on their devices. Our research investigated vibration patterns with the aim of realizing a method that would allow elderly Japanese users to design memorable vibration patterns. Our previous study led to the conclusion that the vibration patterns characterized by the pronunciation of the message could be effectively recognized by the user. Thus, we now present an experimental study based on the proposed message-to-vibration pattern conversion method for designing comprehensible vibration patterns. First, the effectiveness of vibration patterns characterized by Japanese pronunciation factors such as the beat or the alteration in accent was evaluated. Further, we experimented with vibration patterns created by using the volume of the user’s voice during pronunciation. The results confirmed the effectiveness of the method of voice volume-to-vibration patterns.
