20120327006 | USING TACTILE FEEDBACK TO PROVIDE SPATIAL AWARENESS - An image capturing device may be combined with a touch screen to generate a tactile map of an environment. The image capturing device captures an image of the environment which is then processed and used to correlate a point of user contact on a touch screen to a particular tactile sensation. The touch screen may then generate an electric signal (i.e., tactile feedback) corresponding to the tactile sensation which is felt by a user contacting the touch screen. By using the electrical signal as tactile feedback (e.g., electrovibration), the user may determine relative spatial locations of the objects in the environment, the objects' physical characteristics, the distance from the objects to the image capturing device, and the like. | 12-27-2012 |

20130221996 | USER INTERACTIVE LIVING ORGANISMS - Embodiments described herein use capacitive sensing to detect human interaction with living plants. A sensing system may utilize the natural conductive paths found in an organic plant to transmit an electrical signal between the plant and a user interacting with the plant. By directly contacting the plant or coming into proximity of the plant, the user may affect the electrical signal. That is, the electrical properties of the user (e.g., the capacitance of the human body) change a measured impedance curve associated with the electrical signal. Based on this change, the sensing system detects an interaction between the user and the plant and may inform a user interaction device to provide a feedback response to the user. For example, the feedback response may be an audio or video effect that is based on the type of user interaction such as whether the user touched the plant's leaf or stem. | 08-29-2013 |
20140139327 | CONTROLLING A USER'S TACTILE PERCEPTION IN A DYNAMIC PHYSICAL ENVIRONMENT - To maintain consistency in different environments with different impedances, a high voltage current driver may be used as a signal generator to output a tactile signal with a constant current. The constant current ensures that the voltage between the user's finger and the object's surface or electrode remains the same even if impedances in the electrical path change. Specifically, the current driver includes a current sensing circuit that determines the average current being generated. Using a feedback loop, the measured current is compared to a reference current to determine if the correct tactile sensation is perceived by the user. As the impedance changes, the current driver detects the resulting change in the signal's current and adjusts the voltage amplitude of the generated tactile signal in order to match the measured current to the reference current. | 05-22-2014 |
20150015607 | USING VORTICES TO PROVIDE TACTILE SENSATIONS CORRESPONDING TO A VISUAL PRESENTATION - To convey tactile sensations over an open space, a system may use a vortex generator to direct one or more vortices at an object in 3-D space. Once a vortex strikes an object—e.g., a user's hand—it applies a force. The vortex generator can control the frequency and intensity of the vortices in order to provide different tactile sensations that correspond to virtual objects or events in a visual presentation. The system may identify and track objects in the real-world environment, and based on information provided by a device displaying the visual presentation, transmit instructions to the vortex generator to discharge vortices that convey a tactile sensation corresponding to the virtual object or event in the visual presentation. By doing so, the vortices augment the real-world environment to immerse the user in the visual presentation. | 01-15-2015 |
