Description

  The present invention relates to a portable information device provided with a virtual input device such as a mobile phone or a notebook computer.

  In recent years, portable information devices are required to be small and thin because they can be easily carried. For mobile phones and notebook personal computers, the casing is folded to make it portable. Increased configurations are becoming common.

  In particular, mobile phones are striking not only in call functions that are basic functions, but also in advances such as multi-functionality and high performance. For example, advanced functions and additional functions such as connection to the Internet, wireless LAN function, built-in large-capacity hard disk for downloading music information, video information, etc., grasping location information, camera and movie recording function, etc. Must be added.

  On the other hand, from the viewpoints of design and usability, casings such as mobile phones are strongly required to be small, light, and thin. However, as shown in FIG. 14, in the conventional portable information device, the information is displayed so as to be easy to see, for example, the liquid crystal display 610 having the same size as the first case 600 or the second case for inputting information. A keyboard 630 having a size similar to that of 620 is an essential component of the portable information device, and there is a limit to realizing a small size and a thin shape.

  In other words, solving the contradiction of downsizing while improving the function of the portable information device has become a big issue.

  Under the present circumstances, each part is dealt with by downsizing and increasing the density, but there is a limit to downsizing by these.

  Therefore, in order to reduce the size of the portable information device itself, a virtualized input means such as a keyboard has been proposed (see, for example, Patent Document 1 and Patent Document 2).

This is a cellular phone keyboard with keys 1-9, *, 0, #, etc., and a portable information terminal such as a notebook computer or PDA with alphanumeric characters covering the range of AZ and 1-0. This is a virtualized keyboard for the computer. As a result, the virtualized keyboard is projected on a surface such as a desk, and the finger is placed at a predetermined key position on the projected keyboard, so that it is determined and input to which key the finger is placed. .

  However, there is a limit to downsizing individual parts in the above-mentioned portable information device, and the product itself is not easy to use due to excessive miniaturization, high density, narrow pitch, and packing of parts. If the reliability is lowered and the further enhancement of the function is achieved, a bad effect due to the deterioration of the quality occurs.

  Moreover, in the portable information device shown in Patent Document 1 or Patent Document 2, it is necessary to incorporate a large display device such as a liquid crystal display as display means, and there is a limit to thinning. Furthermore, since the display area depends on the size of the display device, there is always a reverse relationship between increasing the size of the display device and reducing the size for easy viewing.

  On the other hand, the conventional display device is difficult to see because the display area is limited. Furthermore, since the positional relationship between the display device and the keyboard is fixed, there is a problem that information cannot be shared in a meeting or the like.

  Further, the second information displayed in the display display area by the projection display device may be displayed by switching between wire frame display and high-definition full screen display depending on the setting.

  Furthermore, the surface of the second housing may have a mat with reflective beads.

  Further, when the input display area or the display display area is set at a position other than the first casing or the second casing, the vibration of the portable information device is detected, and the first information or the second by the vibration is detected. Information blur may be prevented.

  As a result, the visibility of information to be displayed and the security function can be improved, and input errors can be reduced.

(Embodiment 1)
Hereinafter, a portable information device according to Embodiment 1 of the present invention will be described with reference to FIGS.

  FIG. 1A is a perspective view in a closed state of a foldable mobile phone that can be opened and closed as an example of the portable information device in Embodiment 1 of the present invention, and FIG. It is a perspective view of the state of open. FIG. 2 is a perspective view illustrating the portable information device according to Embodiment 1 of the present invention.

  In FIG. 1A, in a portable information device, a first housing 10 and a second housing 20 are connected via a hinge part 30 so as to be opened and closed. As shown in FIG. 1B, the first housing 10 includes a projection type input display device 40, a projection type display display device 50, and an input determination device 60. In addition, as shown in FIG. 2A, the second housing 20 is projected by the input display area 70 displaying the first information projected by the projection input display device 40 and the projection display display device 50. A display display area 80 for displaying the second information is provided. Here, the first information displayed in the input display area 70 is, for example, a virtual key including keys such as 1 to 9, *, 0, and #, and alphanumeric characters that cover a range of A to Z and 1 to 0. Keyboard. Further, the second information displayed in the display display area 80 is, for example, character data and symbols typed with a virtual keyboard or image data stored in a portable information device.

  When the first casing 10 and the second casing 20 are opened at a predetermined opening / closing angle, for example, when the first casing 10 and the second casing 20 are opened at 60 ° to 120 °, preferably 90 °, the first information The second information is displayed in the input display area 70 and the display display area 80 of the second housing 20. Further, when used as a mobile phone, for example, when the opening / closing angle is opened at a predetermined opening / closing angle of 120 ° to 180 °, the display of the input display area 70 and the display display area 80 may be stopped.

  Thereby, since power consumption can be reduced, portability can be improved.

  Here, the projection-type input display device 40 and the projection-type display display device 50 are configured with, for example, a laser or LED having RGB emission wavelengths as a light source. Unlike a projection display device via a liquid crystal panel, the light of a light source is scanned by a DMD (Digital Micromirror Device: registered trademark of Texas Instruments, Inc., USA) manufactured by, for example, MEMS (Micro Electro-Mechanical System). The first information and the second information are projected directly on the input display area 70 and the display display area 80 by scanning with the apparatus.

For example, when an obstacle 90 such as a finger is placed on the keyboard, the obstacle 90 is detected and the input of the virtual key is determined. Here, the input determining device 60 irradiates the obstacle 90 with, for example, infrared rays from an infrared light emitting element (indicated by a solid line in the figure), and detects the reflected light with a detection element such as a photodiode or a phototransistor. It is. As a detection method, for example, the detection can be performed based on an intensity difference or a time difference of infrared reflected light (indicated by a dotted line in the figure) depending on the position of the virtual keyboard. In the above description, the case where there is one input determining device 60 is shown, but a plurality of input determining devices 60 may be provided. Thereby, the detection accuracy of the obstacle 90 can be improved.

  Further, when the movement of the obstacle 90 detected by the input determination device 60 is not detected for a predetermined time, for example, 10 seconds, the display of the input display area 70 and the display display area 80 is stopped, and the movement of the obstacle 90 is again performed. Display may be resumed when detected. Thereby, power consumption can be suppressed and long-time use can be achieved.

  Further, a mat containing reflective beads may be provided at least in the input display area 70 and the display display area 80 of the second casing 20. Thereby, while ensuring visibility, peeping from other directions can be prevented and the security function of display information can be improved. Similarly, a three-dimensional image such as a hologram display can be displayed on the display display area 80 of the second housing 20 by attaching a photopolymer or a deflecting plate, for example.

  Further, the input determination device 60 has two input modes of virtual keyboard input and virtual two-dimensional input that are recognized within the input display area 70 due to the movement of an obstacle. It is also possible to recognize and input the movement of the obstacle according to the input mode.

  That is, in the first embodiment, the virtual information such as a keyboard is displayed as the first information displayed in the input display area 70, and the vicinity of the virtual key position of the virtual keyboard is indicated by the obstacle 90. In the above description, the input mode for recognizing the input of the virtual key is described as an example, but the present invention is not limited to this. That is, by switching the input mode, the first information displayed in the input display area 70 is displayed in a matrix like a grid, for example, and the movement of the obstacle 90 moving in the input display area 70 is changed. It can be recognized as a virtual two-dimensional input and used as input for handwritten character data, chart data, or the like. In this case, the first information may be only a frame indicating the input display area, or may display each intersection point with a point. Thereby, the convenience can be further improved.

  The input mode can be switched by displaying the input mode switching key in the input display area 70 and instructing the input mode with the obstacle 90, or in the input mode of the first casing or the second casing. This can be done with a changeover switch or the like.

  In addition, the first information displayed in the input display area 70 and the second information displayed in the display display area 80 are displayed in a wire frame display and a high-definition full-screen display, for example, by a switch provided in the portable information device. May be switched and displayed. As a result, the amount of data of the displayed image can be converted and displayed according to the application, and the effect is great when it is desired to display at high speed or reduce power consumption.

  As described above, according to the first embodiment of the present invention, a large display device such as a conventional liquid crystal display and an input device such as a press-type keyboard are not necessary. Therefore, a highly reliable, small and thin portable information device that does not cause damage to the press-type keyboard due to repetition can be realized. In addition, circuit elements and devices with other additional functions can be installed in the space occupied by conventional display devices such as liquid crystal displays and press-type keyboards, enabling higher functionality and higher performance without changing the size. Can be realized.
