Abstract
A multimodal haptic device operating as a closed-loop system, the device including a pipeline configured to allow a closed-loop flow of a fluid medium, a manifold operatively connected to the pipeline, the manifold having a pump and a valve to control and regulate a flow of the fluid medium along the pipeline, and a display unit operatively connected to the pipeline, the display unit having a tactile display and a valve operatively connected to the tactile display for regulating an efflux of the fluid medium from the tactile display into the pipeline.
Claims21
A multimodal haptic device comprising:
- a first pipeline for circulating a first fluid, the first pipeline operatively connected to a first pump for controlling at least one of a pressure and a flow of the first fluid, the first fluid having a first temperature;
- a second pipeline for circulating a second fluid, the second pipeline operatively connected to a second pump for controlling at least one of a pressure and a flow of the second fluid, the second fluid having a second temperature;
- and
- a display unit operatively connected to the first and second pipeline and a valve, the display unit having a tactile display, the valve regulating flows of the first fluid and the second fluid between the tactile display and the first and second pipeline, to control both a temperature of the tactile display by mixing the first and second fluids, and a pressure exerted by the tactile display,
- wherein the first and second pipelines and the display unit are arranged to form a closed-loop fluid system.
