Realistically writing and sketching on virtual surfaces in vir-tual reality (VR) enhance the potential uses of VR in productionand art creation. To achieve a similar writing experience as inthe real world, the VR system needs to be pressure sensitive to theuser’s stylus on the virtual plane to create the effect of differentpen strokes and improve the user experience. Typical 6 degree-of-freedom (DoF) VR controllers do not measure force or pressureon surfaces because they are held in mid-air. We propose a newmethod, VirtualForce, to calculate the force based on the differ-ence between the user’s physical hand position and their handavatar in VR. Our method does not require any specialized hard-ware. Furthermore, we explore the potential of our method toimprove the creation of VR art, and we present several ways inwhich VirtualForce can greatly enhance the accuracy of drawingand writing on virtual surfaces in virtual reality.
