In this GO N acoustic field, one or more control points may be defined. An amplitude may be assigned to the control point. Mid-air haptic effect for a 'V virtual object (120) on a human hand (110) may be generated by moving the control point in a single closed curve comprising a plurality 0 \" of curve segments. The single closed curve traverses at least one location where the human hand intersects with the virtual object. ----. Additionally, a user may interact with virtual three-dimensional content using the user's hands while a tracking system monitoring the GO user's hands, a physics engine updates the properties of the virtual Il three-dimensional content and a haptic feedback system provides © haptic information to the user. ei C [Continued on next page] WO 2018/024788 Al MIDEDIMOMMIDIIMERIONIONOMOMMOMEEM SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
