Tactile feedback is useful especially when the user’s auditory and visual modalities are occupied or limited due to social and environmental factors. Recently, we need for more effective notification system as the increase of using high-performance mobile devices and the era of ubiquitous make users obtain massive information from any situation. It is important to analyze user contexts to find factors from the information influenced user’s behaviors and experiences because of various situations and wide range of data in using mobile devices. In this study, to guide the effective use of tactile feedback in the using contexts of a hand-held device, the sensitivity of tactile feedback by measuring the sensitivity of the information by way of the number of vibrotactile signals (numerosity judgement) was compared in the using four experimental contexts divided into the stability of physical movement (standing or walking) and attentional conditions (concentration or distraction). As the results, the accuracy of numerosity judgment decreased in the conditions of physical movement (walking) and distraction. In the hand-held devices, the sensory, perceptual, and cognitive features could be change because of various situations when people hold a device unstably in their hand. Therefore the results of the present study helps us understand the difference in the characteristics of tactile feedback for enhancing the user experience. |
