This Open Access book provides social design insights and implications for HCI research and design exploring digitally mediated touch communication. It offers a socially orientated map to help navigate the complex social landscape of digitally mediated touch for communication: from everyday touch-screens, tangibles, wearables, haptics for virtual reality, to the tactile internet of skin. Drawing on literature reviews, new case-study vignettes, and exemplars of digital touch, the book examines the major social debates provoked by digital touch, and investigates social themes central to the communicative potential and societal consequences of digital touch: · Communication environments, capacities and practices · Norms associations and expectations · Presence, absence and connection · Social imaginaries of digital touch · Digital touch ethics and values The book concludes with a discussion of the significance of social understanding and methods in the context of Interdisciplinary collaborations to explore touch, towards the design of digital touch communication, ?ways of feeling?, that are useable, appropriate, ethical and socially aware. 410 0$aSpringerBriefs in Human-Computer Interaction,$x2520-1670 606 $aUser interfaces (Computer systems) 606 $aTechnology?Sociological aspects 606 $aUser Interfaces and Human Computer Interaction$3https://scigraph.springernature.com/ontologies/product-market-codes/I18067 606 $aScience and Technology Studies$3https://scigraph.springernature.com/ontologies/product-market-codes/X22270 610 $aComputer science 610 $aUser interfaces (Computer systems) 610 $aTechnology?Sociological aspects 615 0$aUser interfaces (Computer systems). 615 0$aTechnology?Sociological aspects. 615 14$aUser Interfaces and Human Computer Interaction. 615 24$aScience and Technology Studies. 676 $a005.437 676 $a4.019 700 $aJewitt$b Carey$4aut$4http://id.loc.gov/vocabulary/relators/aut$0923828 702 $aPrice$b Sara$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aLeder Mackley$b Kerstin$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aYiannoutsou$b Nikoleta$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aAtkinson$b Douglas$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996465459503316 996 $aInterdisciplinary Insights for Digital Touch Communication$92073233 997 $aUNISA
