A floating image display device includes a light source module, a periodical optical structure and a blocking layer. The light source module generates light. The periodical optical structure includes lenses, and the light passes through the periodical optical structure and forms a floating image. The blocking layer is configured to block or absorb a part of the light, and the blocking layer is between any adjacent two lenses. A beam angle of another part of the light not blocked or absorbed by the blocking layer ranges between angles α and β, and the following conditions are satisfied: α=tan(d/h); and β=2 tan(d/2h), wherein α is an off-axis viewing angle, β is an on-axis viewing angle, d is a maximum width of an aperture corresponding to each lens, and h is a distance from the light source module to the aperture.

Light source module

A touch feedback device includes an optical imaging module, an air supplying module, a sensing module, and a signal processing module. The optical imaging module generates a first floating image. The air supplying device forms an airflow field at the outline and/or around the first floating image. The sensing module is configured to sense the change of the airflow field, including the amount of airflow, the air pressure or the speed of airflow caused by the detected object to correspond to a position information. The signal processing module is configured to determine when the position information is inside the preset trigger area of the first floating image outline area, generates at least one feedback command, wherein the at least one feedback command is sent to the optical imaging module to let the optical imaging module generate a second floating image that is different than the first floating image.

Touch feedback device and method for generating touch feedback

A device and a method for generating floating images are provided. An optical imaging module generates a first floating image. A sensing module sends a detection signal to sense first position information of a tested object at a first time point, and generates a feedback signal according to the first position information when the first position information is within a contour range of the first floating image. A signal processing module is electrically connected to the optical imaging module and the sensing module to receive the feedback signal and generate at least one control command and/or at least one feedback command corresponding to the feedback signal. The at least one control command is transmitted to a controller to perform corresponding control on the controller, and the at least one feedback command is transmitted to the optical imaging module, so that the optical imaging module generates a second floating image different from the first floating image.
