Students were shown few videos of earlier projects of TUIs. This videos were Urp, Topobo, Reactable, Tern, Ambient Room, Jarlene, Magic book and many more. They were asked to analyze these videos to define TUI based on their understanding. Here are some early definition proposed by students
Shruthi, Prakash, Aayush, Shambhavi & Linu: TUI is a platform which provides an interaction through actual/percieved sense of touch/tactile objects by creating correlated structure of inputs (along with respective constraints if any) accompanied by various feedbacks
Soumya, Poovri and Pradeep: Tangible user interfaces are interaction mediums which involve physical or tangible inputs to facilitate real or virtual feedback which may or may not have a constrained field of work
Neeraj Talukdar, Amit Jaglan, Saikiran Maguluri: Tangible user Interface is a medium which facilitates in helping the user experience a process analogous to the real world by intuitive input via physical objects and pragmatic outputs with a constraint functionality to decrease uncertainty and to provide the user with focused information
Jatin, Tuhina, Neha: Tangible User Interface is an imitation of real, virtual or digital world experiences, which includes a variety of sensory modatilities with unconstrained types of inputs and constrained constructive outputs.
Ankit, Richa, Bhawna, Safinah, Akash: Tangible User Interface bridges the conventional gap between the Physical and Virtual worlds, where user(s) provides input via physical objects and tactile, real world interactions, which leads to a corresponding computed perceived output in the form of a real time feedback.
