Interactive television has the potential to offer a very engaging experience. But most common user tasks are still challenging with such systems, such as menu selection or text input, and little work has been done on understanding and supporting the effective design of freehand interaction with a TV in the domestic environment. In this paper, we report two studies investigating freehand gestural interaction with a consumer level sensor that is suitable for TV use scenarios. In the first study, we investigate a range of design factors for tiled layout menu selection, including wearable feedback, push gesture depth, target size and position in motor space. The results show that tactile and audio feedback have no significant effect on user performance and preference, and these results inform potential designs for high selection performance. In the second study, we investigate using freehand gestures for the common TV user task of text input. We design and evaluate two virtual keyboard layouts and three freehand selection methods. Results show that ease of use and error tolerance can both be achieved using a text entry method utilizing a dual circle layout and an expanding target selection technique. Finally, we propose design guidelines for effective, usable and comfortable freehand gestural interaction for interactive TV based on the findings.<\/jats:p>","DOI":"10.3233\/jifs-169106","type":"journal-article","created":{"date-parts":[[2016,10,14]],"date-time":"2016-10-14T10:30:59Z","timestamp":1476441059000},"page":"2659-2674","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Towards the design of effective freehand gestural interaction for interactive TV"],"prefix":"10.1177","volume":"31","author":[{"given":"Gang","family":"Ren","sequence":"first","affiliation":[{"name":"School of Digital Arts and Communication, Xiamen University of Technology, Xiamen, China"}]},{"given":"Wenbin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University College London, London, UK"}]},{"given":"Eamonn","family":"O\u2019Neill","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Bath, Bath, UK"}]}],"member":"179","published-online":{"date-parts":[[2016,11]]},"reference":[{"key":"e_1_3_3_2_2","first-page":"935","article-title":"Beyond flat surface computing: Challenges of depth-aware and curved interfaces","author":"Benko H.","year":"2009","unstructured":"BenkoH., Beyond flat surface computing: Challenges of depth-aware and curved interfaces, In Proc MM, 2009, pp. 935\u2013944.","journal-title":"Proc MM"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/1095034.1095041"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijhcs.2012.11.003"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvlc.2009.07.005"},{"key":"e_1_3_3_6_2","article-title":"Technical report, University of Southampton","author":"Karam M.","year":"2005","unstructured":"KaramM. and SchraefelM.C., A taxonomy of gestures in human computer interactions.
