human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "scientific outreach with teegi a tangible eeg interface to talk about neurotechnologies"):
  Abstract: Teegi is an anthropomorphic and tangible avatar exposing a users' brain activity in real time. It is connected to a device sensing the brain by means of electroencephalography (EEG). Teegi moves its hands and feet and closes its eyes along with the person being monitored. It also displays on its scalp the associated EEG signals, thanks to a semi-spherical display made of LEDs. Attendees can interact directly with Teegi -- e.g. move its limbs -- to discover by themselves the underlying brain processes. Teegi can be used for scientific outreach to introduce neurotechnologies in general and brain-computer interfaces (BCI) in particular.

Includes members:
  Member "framework for electroencephalography based evaluation of user experience":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "measuring cognitive conflict in virtual reality with feedback related negativity")
  Member "teegi tangible eeg interface":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "tobe tangible out of body experience")
