ImpAct is a stylus which can dynamically change its effective length and it is equipped with sensors to calculate its orientation in world coordinates. When a user pushes it against a touch screen, physical stylus shrinks and a rendered projection of the stylus is drawn inside the screen giving the llusion that it submerged into the display device. Once user can see the stylus immersed into the digital world below the screen, he/she can manipulate and interact with the virtual objects with active haptic ensations.

Project was developed under masters degree program in Keio Media Design, Keio University, Japan.

ImpAct was demonstrated at ACM UIST 2010, NY and to be published in ACM Computers in Entertainment and ACE 2010, Taipei in November 2010.
