Abstract
The utility model provides a portable projector, comprising an application processor, a projection module, a network module and a control input module. The control input module is a mouse-type touch pad. The control input module also comprises two mouse keys and a track point which are used in junction with the mouse-type touch pad. The portable projector of the utility model realizes flexible and variable control input modes.
Description
Technical field
The present invention relates to a kind of projection arrangement, especially have the portable projection device of touchpad operation function.
Background technology
Projection arrangement has been applied to the fields such as home entertaining, education and instruction, business office widely at present.Along with the development projector of technology also more and more miniaturization and portability, its application also constantly enlarges.As shown in Figure 1, existing portable projection device 10 all is to carry out control inputs by the control button 11 that is arranged on the portable projection device generally.But development and maturation along with information-based, intellectuality, networking and embedded system technology, multi-functional, high integrated a large amount of being applied in the portable projection device of digital terminal technology causes this traditional button operation pattern can't satisfy flexible and changeable operational requirements.
Summary of the invention
In order to address the above problem, a kind of portable projection device provided by the invention comprises, application processor, projection module and control inputs module, and described control inputs module is mouse-type touch pad.
The present invention also provides a kind of portable projection device to comprise application processor, projection module and control inputs module, and described control inputs module is a TrackPoint, and comprises two mousebuttons that cooperate TrackPoint to use.
Compared to prior art, the control inputs module of portable projection device of the present invention can realize flexible and changeable control inputs mode.
Description of drawings
Fig. 1 is the control button synoptic diagram of existing portable projection device;
Fig. 2 is the portable projection device structured flowchart according to the embodiment of the invention.
Specific embodiments
Fig. 2 is the portable projection device structured flowchart according to the embodiment of the invention, and as shown in Figure 2, portable projection device comprises application processor 21, projection module 22, mixed-media network modules mixed-media 23, control inputs module 24 and built-in power 25.Above-mentioned control inputs module 24 is to consist of with mouse-type touch pad, and this mouse-type touch pad is a kind of in condenser type or the resistance-type, and touch pad is known the finger situation of movement by capacitive sensing.When finger contact arrived the plate face, the electrostatic field on the plate face can change.Touchpad sensor is one and is imprinted on the lip-deep finger trace transmission line of plate.And this track can ceaselessly be measured and report out to a special surface-mounted integrated circuit under touchpad surface, thereby find out action and the position of finger.The user is by the finger that slides at above-mentioned touch pad, and corresponding cursor moves in the display frame that goes out by projection module 22, the same with touch pad commonly used, touching continuously after twice on the touch pad, application processor 21 can be judged as " determining ", and opens corresponding file or carry out corresponding function.Above-mentioned portable projection device also comprises two mousebuttons that are used with described mouse-type touch pad, and its using method is identical with the right and left key of function and mouse.The mouse roller that can also comprise operations such as carrying out that picture slides up and down in the control inputs module of above-mentioned just formula projection arrangement.
The touch pad of above-mentioned control inputs module 24 also can adopt and utilize pressure sensitive to carry out controlling resistance formula touch pad.
The control inputs module 24 of above-mentioned portable projection device can be a TrackPoint and two mousebuttons that cooperate the TrackPoint use.Above-mentioned TrackPoint forms at the projection arrangement rat, when external force is applied on the TrackPoint, at once cause the potsherd of TrackPoint bottom that slight deformation occurs, the resistance of potsherd changes thereupon, therefore produce different electric signal, application processor 21 is analyzed these different electric signal just can judge moving direction and the translational speed that cursor is different.
The control inputs module 24 of above-mentioned portable projection device also can have touch pad and TrackPoint simultaneously, makes the user select freely the input mode of liking.
The mixed-media network modules mixed-media 23 of above-mentioned portable projection device can be wired ethernet, wireless WIFI, honeycomb such as 3G/4G or combinations thereof, connects the Internet network with convenient by common Ethernet, wireless ethernet or mobile radio communication.
Also comprise at least two USB interface in above-mentioned portable projection device, the user can carry out exchanges data by above-mentioned interface and projector, or connects external equipment.
