Week 1 Research and Definitions

Analyzing the project brief and task at hand through defining terms.

'This semester un particular forcuses on the topics of social awareness, tangible interactions, use of assistive technologies and fundamentals of products that include electronic componentry.'

Assistive technology/ Adaptive technology(AT) is: a term that includes assistive, adaptive and rehabilitative devices for people with disabilities. It also includes the process used in selecting, locating and using them. AT promotes greater independence by enabling people to perform tasks that they were formerly unable to accomplish. Providing enhancements to or changed methods of interacting with the technology needed to accomplish such tasks.



Tangible, synonyms: touchable, physical, substantial, perceptible, concrete

Tangible interactions represent systems that rely on:

• Tangibility/materiality
• Bodily/embodied interaction
• physical representation of data
• embeddedness in real space, and augmentation of physical spaces (improvement or enchancement)

Research questions:

• What is the user experience of tangible interaction?
• Why does tangible interaction work so well for users?
• How can we conceptualize the social aspects of tangible interaction?
• Which concepts can we employ and what perspectives take for analysing and evaluating systems?
• Which concepts can we employ and what perspectives take for analyzing and evaluating systems?
• Are there concepts that cn guide or inspire the design of new systems?

Examples of tangible interaction are:

• Haptic direct manipulation, with distinct tactile qualities.
• Spatial Interaction, interaction occurs by movement in space, our body is the reference point in space. 
• Embodied facilitation, refers to how the configuration of material objects and space affects and directs emerging group behavior.
• Expressive representation, focuses on the material and digital representations employed by tangible interaction systems, their expressiveness and legibility.

Important aspects to tangible interactions:

• All users get relevant access
• Are all representations logical, expressive and meaningful?
• Are there non-literal representations that transform the problem?
• Can the user interact with the relevant parts.

(this focuses on Spatial Interaction and Embodied Facilitation, putting the themes in context to the discussions about the space-place distinction - which in my view is purely theoretical, as human experience of space is always situated, spatial constraints directly influencing our perception of space and our behaviors - this is stuff for further work on)
