Problems solved by technology

[0007] However, the conventional interactive system including the technology disclosed in Japanese Patent Application Laid-Open No. 2012-185798 has difficulty in simultaneously recognizing a plurality of pointers
Therefore, there is a problem when manipulating the projection surface with multiple pointers, which constitutes an obstacle to more accurate interactive operation

[0032] System Configuration

[0033] figure 1 A system configuration diagram showing an interactive system according to the first embodiment. As an example, the interactive system according to the first embodiment includes a projector device 1 , a pen 2 , a personal computer device 3 , a photographing unit 5 and a laser module 6 . Via such as HDMI for inputting images TM A video cable 7 connects the projector device 1 and the personal computer device 3 . hdmi TMIt is the abbreviation of "High Definition Multimedia Interface (HighDefinitionMultimediaInterface)". In addition, the projector device 1 and the personal computer device 3 are connected by a limited cable 8 such as a USB cable for transmitting and receiving operation information. USB is the abbreviation of "Universal Serial Bus (Universal Serial Bus)". Additionally, the projector device 1 and the personal computer device 3 can be TM ) near field communication to transmit and receive operational information.

[0066] Subsequently, an interactive system according to the second embodiment is explained. When the projection surface 4 is operated with one pen 2 , the operation direction calculated from the captured image is the operation direction of the pen 2 . Therefore, when the projection surface 4 is operated with one pen 2 , it is not necessary for the projection device 1 to perform a process of associating the operation direction calculated from the captured image with the unique identification information of the pen 2 .

[0067] From this point of view, in the second embodiment, the above-described association processing is performed when the projection surface 4 is operated with a plurality of pens 2 . Additionally, the second embodiment described below differs from the first embodiment described above only in this point. Therefore, only differences from the first embodiment are described below to omit redundant descriptions.

[0072] Subsequently, an interactive system according to a third embodiment is explained. In the interactive system according to the third embodiment, projector device 1 recognizes a pointer to operate projection surface 4 and enables interactive control. That is, in the case of the third embodiment, projector device 1 recognizes pen 2 and a pointer such as a finger different from nozzle 2 and enables interactive control. Additionally, the third embodiment described below differs from the above-described embodiments only in this point. Therefore, only differences from the first and second embodiments are described below to omit redundant descriptions.

[0073] Figure 8 The flowchart of shows the flow of the operation of the projector device 1 installed in the interactive system according to the third embodiment. In the case of the third embodiment, in Figure 7 The processing in step S21 is additionally added between step S14 and step S15 in the flow chart of . Also, if t...

Abstract

The invention provides a projector device, an interactive system, and an interactive control method. The projector device includes: a projecting unit that projects a projection image onto a projection surface; a receiving unit that receives information transmitted from a pointer operating the projection surface, the information including unique identification information of the pointer and first operation direction information indicating an operation direction of the pointer; a photographing unit that photographs the projection surface; a generating unit that generates second operation direction information indicating an operation direction of the pointer operating the projection surface from multiple photographed images taken by the photographing unit; an associating unit that associates the second operation direction information matching with the first operation direction information with the unique identification information; an operation-information generating unit that generates operation information including the associated unique identification information and second operation direction information; and a transmitting unit that transmits the generated operation information to a controlled device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2014-137201 filed in Japan on Jul. 2, 2014 and the entire contents thereof are hereby incorporated by reference. technical field [0003] The invention relates to a projector device, an interactive system and an interactive control method. Background technique [0004] In recent years, an interactive system that detects an operation on a screen projected by a projection device (image projection device) and enables operation of a device such as a projector device or a personal computer device has been known. In the case of this interactive system, when the user operates the projection surface with an electronic pen, pen, his / her finger, etc., a cursor or pointer, etc. on the projection surface is moved and displayed according to the operation. Also, in the case of this interactive system, when the user touches a desired position on the projection sur...
