A moderate-to-severe acquired brain injury (ABI) can have tremendous lifelong consequences for ABI-survivors and their families. Despite rehabilitation practice since the 1980s aspiring to a dynamic, coherent and holistic approach, the psychological dimension still seems to be a challenge and research has revealed persisting psychosocial impairments after ABI. Therefore, we developed BackUp©, a manual based short term psychological intervention for adults with ABI. This study explores the effect of the intervention though a small feasibility study, employing a single case design. One client received the intervention. Self-report measures were collected, and a semi structured interview was conducted. While results from pre, post and follow-up measures do not show clear positive results, the interview reveals positive experiences and the participant reported achieving his therapy goal. This case study provides support for a psychological intervention to support the psychological rehabilitation after an ABI.

Affordances is an important term in the field of Shape-Changing Interfaces (SCI). But the field is challenged by a multitude of vaguely defined concepts around affordances such as dynamic, spatial, or tactile affordances. In line with this, Alexander et al [1] recently pointed to lack of theory as one of the grand challenges for SCI. This paper proposes a re-analysis of Gibson for resolving the conceptual cacophony in the field of SCI. Essential to the ecological approach to affordances, is that perception is dynamic and people pick up information through exploring objects and environments over time. From this perspective, affordances of Shape-Changing Interfaces become a matter of providing Information-through the design-regarding a) the interfaces' ability to transform its shape and b) how movement suggests level of animacy. Through analyzing scholarly SCI prototypes, from this perspective, we provide an initial set of design strategies for affordances of shapechanging interfaces.

Gibsons teori har dannet rammen for den såkaldte økologiske tilgang til perceptionsteori og til psykologi i almindelighed. Både inden for og uden for denne tilgang er der en del teoretiske diskussioner om forskellige svagheder ved Gibsons teori. Denne artikel tager afsæt i en forståelse af denne teori med særlig interesse i det begreb om ‘tjenligheder’, som er et kernebegreb i teorien. Denne forståelse føres videre i en diskussion af nogle af de svagheder ved teorien, som tidligere er identificeret, og hovedargumentet er her, at de problemer, der opstår, når den økologiske tilgang skal anvendes inden for andre områder end det perceptuelle, skyldes et implicit og udifferentieret aktivitetsbegreb. Et eksplicit og differentieret aktivitetsbegreb findes i virksomhedsteorien, som den blandt andet præsenteres af Leontjev, og sidst i artiklen vil denne teori blive forsøgt knyttet til den økologiske teori for at kunne forstå de forskellige aktivitetsniveauer, der findes i tjenlighedsbegrebet.
