Abstract
The utility model discloses portable electronic equipment and an input device thereof, which are convenient to install a biggest display screen and convenient for users to simultaneously operate keys and a touch pad. The scheme is as follows: the input device comprises a touch pad which is arranged on the back surface of the portable electronic equipment, a sensor which is connected with the touch pad and detects the position of user operation on the touch pad, and a coordinate generating module which is connected with the sensor and generating a coordinate with a corresponding position according to the installation direction of the touch pad on the back surface of the portable electronic equipment.
Description
Technical field
The utility model relates to the input media of mancarried electronic aid, relates in particular to the input media of super portable mobile computer.
Background technology
Existing mancarried electronic aid designs Trackpad in the equipment front usually, but there is following shortcoming in design like this: (1) takies the space in equipment front, because display screen is installed in the equipment front, obviously can take and originally be used to the space that shows at the positive Trackpad of installing of equipment, reduce user experience; (2) keyboard can be designed in the front of part mancarried electronic aid, because Trackpad also designs in the front, very inconvenience can become when the user needs while operation keyboard and Trackpad.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of input media of mancarried electronic aid is provided, and is convenient to install big as far as possible display screen, is convenient to the user and need carries out the operation of button and Trackpad simultaneously.
Another purpose of the present utility model is to provide a kind of mancarried electronic aid.
The technical solution of the utility model is: the utility model discloses a kind of input media of mancarried electronic aid, comprising:
Trackpad is installed in the back side of this mancarried electronic aid;
Sensor connects this Trackpad, and the detection user operates in the position on this Trackpad;
The coordinate generation module connects this sensor, generates the coordinate of this position correspondence according to the installation direction of this Trackpad at the mancarried electronic aid back side.
According to an embodiment of the input media of mancarried electronic aid of the present utility model, this Trackpad comprises capacitive touch control plate.
The invention also discloses a kind of mancarried electronic aid, comprise input media, this input media comprises:
Trackpad is installed in the back side of this mancarried electronic aid;
Sensor connects this Trackpad, and the detection user operates in the position on this Trackpad;
The coordinate generation module connects this sensor, generates the coordinate of this position correspondence according to the installation direction of this Trackpad at the mancarried electronic aid back side.
According to an embodiment of mancarried electronic aid of the present utility model, this Trackpad is a capacitive touch control plate.
The utility model contrast prior art has following beneficial effect: the utility model is by being installed in Trackpad at the back side of mancarried electronic aid, because installation direction is installed with respect to the front variation has taken place, further finished generative process based on the coordinate of installation direction by the coordinate generation module.The contrast prior art, the bigger display screen of design as much as possible under the situation that can't increase equipment volume has further facilitated user's operation simultaneously, especially simultaneously to the operation of button and Trackpad.
Description of drawings
Fig. 1 is the synoptic diagram at the back side of mancarried electronic aid of the present utility model.
Fig. 2 is the schematic diagram of embodiment of the input media of mancarried electronic aid of the present utility model.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
See also Fig. 2, the input media of mancarried electronic aid of the present utility model comprises Trackpad 10, sensor 12, coordinate generation module 14.Annexation between these modules is: the input of sensor 12 connects the output of Trackpad 10, and the input of coordinate generation module 14 connects the output of sensor 12.
Present embodiment the most important thing is the installation site of Trackpad 20, that is, Trackpad 20 as shown in Figure 1 is installed in the back side of mancarried electronic aid 2.As for the principle of work of Trackpad 20 itself, be technology known in the art, for example can adopt capacitive touch technology.Capacitive principle of work is: when user's finger changes electric capacity during near Trackpad 20, the control IC of Trackpad 20 oneself will detect electric capacity change amount, thereby induce the position of finger.
Sensor 12 can induce its position on Trackpad pressing of Trackpad 20 according to user's finger, and then is finished the generation and the output of respective coordinates by coordinate generation module 14.In the present embodiment, coordinate generation module 14 also is a key point.For the use habit (direction of touch track and thinking direction are in full accord) that does not influence the user, this need improve the process that coordinate generates, that is, generate coordinate according to the installation direction of Trackpad 20, could be under the situation that does not influence user's use habit the position of Trackpad be moved on to the back side at the equipment back side.Coordinate generation module 14 specifically may be implemented in the PS2/I2C/SPI interface routine of equipment.
The utility model has also disclosed a kind of mancarried electronic aid, and this mancarried electronic aid has comprised the input media of the foregoing description.Because the improvement of mancarried electronic aid is the input media of the foregoing description, so do not repeat them here.
The foregoing description provides to those of ordinary skills and realizes or use of the present utility model; those of ordinary skills can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
