Haptic Learning
Final Report Abstract
In summary, the project has reached most of its major goals: (i) the development of innovative haptic interface devices (iObject+, Twistor) to study manual haptics at high spatial resolution and to support fMRI and behavioral experiments to obtain insights into representations of haptic interaction; (ii) the measurement of haptically driven brain activity in fMRI scans with and without learning in a novel experimental splitting paradigm; (iii) the development of human/robotic behavioral experiment for object recognition and handling; and (iv) the development of a neurodynamic model that can capture some aspects of the processes in a closed haptic sensori-motor loop that establish higher level representations of object features and object-in-hand state from pixel based contact patterns at the finger tips. The cooperation between the German and the Japanese teams linked brain imaging experiments of the Japanese side with the development of a neurodynamic model and robot experiment on the German side. This was strengthened by behavioral experiments conducted on both sides and covering complementary aspects, utilizing the developed haptic interface devices. Besides results in basic research, the technology developments contribute to the development of haptic smart objects with potential applications in the tactile internet.
