Element comprising sensors for detecting grab motion or grab release motion for actuating inter-element holding or releasing

A system, comprising:

• a motion module;
• and
• at least a first element, a second element, and a third element, each of the first element, the second element, and the third element being three-dimensional, and including:
• holding means, adapted for interacting with a functionally aligned other holding means of a similar element, and comprising a holding state and a released state, said holding means in said holding state engaged with said aligned holding means of said similar element for holding said element positioned with respect to said similar element, and in said released state disengaged with said aligned holding means, and
• sensing means for providing grab-detection, said grab-detection including detection of one selected from an action leading to a grip of said element, an actual grip of said element with subsequently a release of a grip of said element;
• a centre point in said element;
• at least one face coupled to said centre point, said at least one face including a motion-guiding module, defining a trajectory over at least part of said face, and a motion-restriction module, adapted for limiting the displacement of said centre point with respect to said centre point of one of the other elements to at least one trajectory selected from the group consisting of said trajectory and said trajectory of said other element, when interacting with said motion module,
• wherein said sensing means is functionally coupled to said holding means for upon said grab-detection actuating at least one of said functionally aligned holding means between said holding state and said released state,
• wherein said motion module is adapted to be coupled to a face of one of said elements, and adapted for displacing said centre point of said one element with respect to said centre point of one of the other elements when interacting with the motion-guiding module of said one of the other elements, said motion-guiding module, said motion module and said motion-restriction module defining different module types,
• wherein for displacing said centre point of said first element away from said centre point of said second element and towards said centre point of said third element, a first face of said at least one face of said first element faces at least one of a second face of said at least one face of said second element and a third face of said at least one face of said third element, thus providing facing faces, and
• wherein for said displacing, said motion module interacts with at least one motion-guiding module, and with at least one motion-restriction module, with said facing faces providing said interacting modules while displacing, at least one module of said first face interacts with at least one module of at least one different module type of at least one other of said facing faces while displacing, and said at least one module of said first face interacts with at least one module of a different module type of said second face and at least one module of a different module type of said third face,
• wherein said modules of said first face, said second face, and said third face interact alternatingly while displacing.
