Assessment of users’ impressions of mobile devices’ vibrations and how such impressions affect the recognition of information

Abstract

Intelligent personal assist systems such as Apple’s Siri and Google Now are becoming more and more ubiquitous. In this study, we examine the presentation of information by an intelligent personal assistant system to determine whether the manner of information transmission varies by adding vibration to information. We suggest the following: (a) Adding vibration to information affects impression changes, regardless of the quality of information; (b) When adding vibration to information, the positive impression change is in the order of no vibration < interval pf 1000 ms < interval of 100 ms; (c) Concerning the degree of negativity, the most negative impression is received at an interval of 1000 ms.
