    Empathic vehicle design: Use cases and design directions from two workshops
    Nadri, Chihab; Alvarez, Ignacio; Bosch, Esther; Oehl, Michael; Braun, Michael; Healey, Jennifer; Jallais, Christophe; Ju, Wendy; Li, Jingyi; Jeon, Myounghoon (ACM, 2022-04-27)
    Empathic vehicles are expected to improve user experience in automated vehicles and to help increase user acceptance of technology. However, little is known about potential real-world implementations and designs using empathic interfaces in vehicles with higher levels of automation. Given advances in affect detection and emotion mitigation, we conducted two workshops (N1 =24, N2 = 22, Ntotal = 46) on the design of empathic vehicles and their potential utility in a variety of applications. This paper recapitulates key opportunities in the design and application of empathetic interfaces in automated vehicles which emerged from the two workshops hosted at the ACM AutoUI conferences.

    Evaluating the Impact of Training on the Effectiveness of Peer Change Agents: A Campus-wide Intervention
    Roediger, Micah (Virginia Tech, 2015-05-04)
    The current study investigated the impact of a training program on a peer-to-peer intervention designed to increase the use of bicycle helmets on a large college campus. The training program was evaluated by the number of interactions a peer change agent--an individual who attempts to make a positive change in another person's behavior, had with bicyclists. The results suggest the training program may be effective in increasing change agent interactions for change agents who are already commitment to the intervention leading to more interactions per capita between committed trained change agents and bicyclists than untrained change agent and bicyclists. However, these results must be interpreted with caution due to small and unequal sample sizes.

    A Field Investigation of Implicit Theory Congruence in Leader-Follower Relationships
    Coyle, Patrick (Virginia Tech, 2015-06-17)
    The purpose of the following study was to investigate the role of interpersonal congruence between leaders' and followers' implicit theories of leadership (ILTs) and followership (IFTs) in both partners' perspectives of the leader-follower relationship. While most literature focuses on assessments of the leader-member exchange (LMX) relationship, this study examined perceived support, identification with one's partner, and contribution to the relationship, in addition to LMX. Congruence between self-views and interpersonal congruence on implicit theories was examined as moderators of these relationships, such that the strength of these relationships was predicted to increase as self-views aligned more highly with implicit theories. Data from 103 independent pairs of full-time working adults (across an organizational sample as well as varied workforce snowball sample) were analyzed using eight manifest path models. Leader ILT -- follower ILT congruence significantly and positive predicted leader-rated LMX and perceived support, but not identification and contribution. Leader IFT -- follower IFT congruence significantly and positive predicted follower-rated LMX and perceived support, but not identification and contribution. The results of this study suggest expectations are meaningful predictors of both partner's assessments of multiple relationship-oriented outcome variables, but only with regard to perceptions of outcomes from the perspective of one's dyadic partner.
