Thinker Thing

Because 3D printers build objects layer by layer from materials such as plastic or metal dust, a key advantage is the comparative freedom they give designers. Yet the design software is not easy to master, especially if you are four-years-old and haven’t yet learnt to hold a pencil properly. Emotional Evolutionary Design (EED), allows Thinker Thing to interpret its users’ thoughts. Its current role is to power the Monster Dreamer Project, which will allow users to design their own objects using the power of thought. Children will get the opportunity to try it out during tour of schools in the country at the end of this month.The children’s reactions to the changes will be picked up by an Emotiv EPOC headset, a $300 electroencephalography (EEG) device designed to pick up the electrical signals from brain cell interactions using fourteen sensors on the scalp. As different brain states such as excitement or boredom generate specific patterns of brain activity, the computer can identify the shapes associated with positive emotional responses. The favoured shapes will grow bigger on the screen, while the others shrink. The biggest shapes are combined to generate a body part, and the process is repeated for different body parts until the object is complete. The final result should be a unique 3D model that is ready for printing as a solid object.
This toy arm is the first object from thought successfully created by the start-up.
The shape and form of the toy limb was determined from a headset picking up a person’s brainwaves.
