Tactile communication may become an important element of human\u2013robot interaction (HRI), but it requires the development of messaging capabilities approaching the communication power of the speech and visual signals used in the military. <\/jats:p><\/jats:sec><jats:sec><jats:title>Method:<\/jats:title><jats:p> In Experiment 1 ( N = 38), we trained participants to identify sets of directional, dynamic, and static tactons and tested performance and workload following training. In Experiment 2 ( N = 76), we introduced an extended training procedure and tested participants\u2019 ability to correctly identify two-tacton phrases. We also investigated the impact of multitasking on performance and workload. Individual difference factors were assessed. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> Experiment 1 showed that participants found dynamic and static tactons difficult to learn, but the enhanced training procedure in Experiment 2 produced competency in performance for all tacton categories. Participants in the latter study also performed well on two-tacton phrases and when multitasking. However, some deficits in performance and elevation of workload were observed. Spatial ability predicted some aspects of performance in both studies. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> Participants may be trained to identify both single tactons and tacton phrases, demonstrating the feasibility of developing a tactile language for HRI. <\/jats:p><\/jats:sec><jats:sec><jats:title>Application:<\/jats:title><jats:p> Tactile communication may be incorporated into multi-modal communication systems for HRI. It also has potential for human\u2013human communication in challenging environments. <\/jats:p><\/jats:sec>","DOI":"10.1177\/0018720814548063","type":"journal-article","created":{"date-parts":[[2014,8,29]],"date-time":"2014-08-29T04:26:16Z","timestamp":1409286376000},"page":"471-490","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Toward a Tactile Language for Human\u2013Robot Interaction"],"prefix":"10.1177","volume":"57","author":[{"given":"Daniel J.","family":"Barber","sequence":"first","affiliation":[{"name":"University of Central Florida, Orlando"}]},{"given":"Lauren E.","family":"Reinerman-Jones","sequence":"additional","affiliation":[{"name":"University of Central Florida, Orlando"}]},{"given":"Gerald","family":"Matthews","sequence":"additional","affiliation":[{"name":"University of Central Florida, Orlando"}]}],"member":"179","published-online":{"date-parts":[[2014,8,28]]},"reference":[{"key":"bibr1-0018720814548063","first-page":"483","volume-title":"Proceedings of the Army Science Conference","author":"Barber D.
