1. Technical Field
The present invention generally relates to computers, and particularly to a computer with a virtual keyboard and a virtual display.
2. Description of Related Art
With the continuing development of technology, computers have been widely used in our daily life.
Currently, a typical computer includes a host, a keyboard, a mouse, and a display. However, this computer is very undesirable since the keyboard and display occupy a large space and are not convenient to carry when the computer is required to be moved from one place to another.
What is needed, therefore, is a computer which overcomes the described limitations.
A computer includes a host. The host includes an enclosure, a circuit board and a projection system both enclosed in the enclosure. The enclosure defines a projection hole therein. The projection system electrically connects with the circuit board. The projection system aligns with the projection hole for projecting information of the computer on a wall via the projection hole. The host further comprises a virtual keyboard system therein, which can project a virtual keyboard on a top of a desk. By the virtual keyboard, a user can enter data into the computer and operate the computer.
Other advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Many aspects of the present computer can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosed computer. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The enclosure 11 includes a housing 111 and a cover 112 engaging a lateral side the housing 111 to cover a lateral opening (not labeled) thereof. The housing 111 defines a camera hole 113, a plurality of universal serial bus (USB) ports 116, a projection orifice 115 and a power supply socket 118 at a front face of the housing 111 along top-to-bottom direction. In addition, a power switch 117 is provided at the front face of the housing 111 between the projection orifice 115 and the power supply socket 118. Referring to
Referring back to
The virtual keyboard system 15 aligns with the projection orifice 115. The virtual keyboard system 15 is used to emit laser lights and thus project a virtual keyboard 16 (shown in
The projection system 13 aligns with the projection hole 114, and is used to project information of the computer out of the host 111 via the projection hole 114. The projection system 13 has same structure and operating principle as those of a typical projection system.
Referring to
In the computer, the projection system 13 and virtual keyboard system 14 are enclosed in the enclosure 11, and the enclosure 11 defines the projection hole 114 and projection orifice 115 aligning with the projection system 13 and virtual keyboard system 14, respectively. Thus, the computer can input and display signals without an additional keyboard and an additional display, which simplifies its structure and reduces its size.
It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
