1 Haptic Warning Signals at the Steering Wheel: A Literature Survey Regarding Lane Departure Warning Systems (Short Paper) F. Beruscha, K. Augsburg, D. Manstetten, Vol. 5, No. 1, 13-May-2011

ABSTRACT Using the haptic modality to transfer information to the driver is recognized as a promising possibility in many in-vehicle applications. In the field of lane departure warning systems, several haptic warning signals were presented in the last years. The application of synthetic steering wheel torque or vibration informs the driver of an imminent lane departure. In this paper, an approach to classify the existing signals is pro- vided. The examination of the literature reveals diversity in type and parameterization of the warning signals as well as methodical differences, complicating comparability. While the general effectiveness of haptic warning signals at the steering wheel could be proven, there still is room for im- provement. Based on the findings, the authors derive hy- potheses concerning requirements from a user’s point of view.

1 Haptic Identification of Raised-Line Drawings by Children, Adolescents, and Young Adults: An Age-Related Skill (Short Paper) Delphine Picard, Jean-Michel Albaret, Anais Mazella Vol. 5, No. 2, 24-Jul-2013

ABSTRACT Past research involving adult participants has consistently shown that the identification of raised- line drawings through haptics was challenging. In the present study, we used a developmental approach to assess whether this skill was related to age and haptic short-term memory capacity. To that end, we asked sighted children, adolescents, and young adults to identify raised-line drawings of common objects by touch. We also measured their haptic short-term memory capacity. Results showed that picture identification scores and memory spans both improved significantly with age. Interestingly, memory scores accounted significantly for the variability in picture identification scores. These findings suggest that identifying raised-line drawings through haptics is an age-related skill. Improvement in haptic short-term memory capacity may play a role in the development of that skill.
