Abstract
Disclosed herein is a dynamically shapeable haptic interface, which can include a drive mechanism, a tactile mechanism, and a display. The display can emit light towards the drive mechanism in the form of image(s). The emitted light can activate a plurality of switches located between coil(s) included in the drive mechanism and the display. The plurality of switches, when activated, can allow current(s), supplied by a source, to pass through the coil(s). The current passing through the coils can create magnetic fields. The magnetic fields can collectively form a magnetic profile. The magnetic profile can cause the tactile mechanism to render shape(s) on the surface of the haptic interface. The tactile mechanism can include magnetic component(s), such as ferrous particles, magnets, and/or magnetic pins. The magnetic component(s) can move based on the magnetic profile and, along with one or more layers of material, can render the shape(s).
