It is to be appreciated that " mesa region " alleged by the present invention not only includes the region where the upper surface of table top 10, also
Including the region above the upper surface of table top 10, for example it is placed on the article 11 of the upper surface of table top 10 and falls within mesa region.
Also referring to Fig. 3-6, for the customer of different heights, because the height of eyes is different, same thing is observed
The visual angle of product has differences, and then produces parallax.Due to the presence of parallax, the customer of different height is after transparent panel 20 is observed
During the article of side, sight can fall in the different positions of transparent panel 20.For example Fig. 3 shows 1 meter 58 to 1 meters 6 of customer's
Cross position of the sight from the article 11 of different rows on transparent panel 20, Fig. 4 show the sight of 1 meter 88 to 1 meters 9 of customer
From cross position of the article 11 of different rows on transparent panel 20.As can be seen that the customer relatively low compared to height, higher Gu
The position that the sight of visitor falls on transparent panel 20 is also higher, and can be partial to staff side.And work as customer's selected item
When being touched on transparent panel 20, it can tend to fall the position on transparent panel 20 according to sight and touched.Clearly as
The reason for parallax, the different customer of height also differ for the touch location of same article.For same customer, by institute
The left and right of station location and front and rear difference, observing the visual angle of same article can also have differences, and then produce parallax.Therefore, it is necessary to
The mapping relations between touch area and mesa region are corrected according to the height of customer and erect-position, make different heights and station
The customer of position can choose required article exactly.
Specifically, for same article or same mesa region, control module 400 is to different heights, different sight
The position of touch area set by the customer of height or different erect-positions is different, especially, as shown in Figure 3-4, touch area
Height is directly proportional to the height or height of sighting line of customer.I.e. customer is higher, touching corresponding to same article or same mesa region
It is also higher to touch region.For same article or same mesa region, control module 400 is to different heights or height of sighting line
The distance of touch area set by customer is also different, and especially, the height or height of sighting line of customer is higher, and touch area is relative
The distance of customer is more remote.I.e. customer is higher, and the touch area corresponding to same article or same mesa region is more remote from customer.And
And there is also certain relation for the position of touch area and the erect-position of customer.As illustrated in figures 4-5, the erect-position of customer is apart from sales counter 100
More remote, the touch area corresponding to same article or same mesa region is more on the lower;The erect-position of customer is nearer apart from sales counter 100,
Touch area corresponding to same article or same mesa region is more top.As shown in fig. 6, same mesa region is shown altogether
The customer's height or height of sighting line phase of 3 sights and the position that crosses of the transparent panel 20 of sales counter 100, wherein two, left side sight
Together, but deviate mesa region degree it is different.The sight of the leftmost side is to the left with respect to mesa region, and middle sight face table top
Region.The height or height of sighting line of the customer of the sight on the right is relatively low, and is deviated to the right mesa region.By three sights with it is transparent
The position that crosses of panel 20 can be seen that the erect-position of customer is more to the left with respect to sales counter 100, and same article or same mesa region institute are right
The touch area answered is more to the left;The erect-position of customer is more to the right with respect to sales counter 100, the touch corresponding to same article or mesa region
Region is more to the right.
In a kind of implementation, the corresponding relation of touch area and mesa region for control module 400 according to customer's height,
Erect-position and the corresponding relation of default height, erect-position scope and customer's visual line of sight are configured.Before customer comes sales counter 100
When, height induction installation 500 can automatic detection customer height and erect-position.Different heights are previously provided with control module 400
With the sight data of the customer of erect-position, set touch area is corresponding with mesa region to close according to the height of customer and erect-position scope
System, it may be such that the setting of touch area adapts to the height and erect-position of customer, consequently facilitating customer carries out touch selection.By this
Mode, the touch area adjustment of automation can be achieved.Such as the customer that height is higher or erect-position is forward, for each
The position of remote corresponding touch area is heightened or adjusted to article;For height is shorter or erect-position customer rearward, for each article
The position of nearly corresponding touch area is turned down or adjusted, the customer to be kept left for erect-position, offsets corresponding touch to the left for each article
The position in region is touched, the customer to be kept right for erect-position, offsets the position for corresponding to touch area to the right for each article.
With reference to figure 7, in another implementation, correction identifier 12 is provided with table top 10, correction identifier 12 is set
It is placed in the center of table top 10.Certainly, correction identifier 12 may also set up in the other positions of table top 10, such as the upper left corner, this reality
Mode is applied to be not specifically limited this.Correction identifier 12 can also be arranged on the article 11 on table top 10, such as in food
Pallet on.Correcting the shape of identifier 12 can be geometry, can be combination of word and pattern etc., present embodiment pair
This is not specifically limited.Before customer selects article, customer is prompted in the forward observation of transparent panel 20 correction identifier 12
Position, then touched in the position of the corresponding correction identifier 12 of transparent panel 20.Can be by the display information of sales counter 100, defeated
Go out acoustic information etc. to be prompted, or guided by staff.The position of the corresponding correction identifier 12 of transparent panel 20
Put the position that crosses for referring to the sight of customer's orientation-correcting identifier 12 with transparent panel 20.Thus, customer passes through in transparent area
The position of corresponding correction identifier 12 is touched on plate 20, and control module 400 can go out according to the touch location calculation of customer
The height of sighting line and erect-position of customer, and then touch area corresponding to each mesa region of setting, make it be adapted to different heights and station
The touch location of the customer of position.Touch location when identifier 12 is corrected according to selection touches corresponding to setting each mesa region
The reason for region, is, for the customer of different heights and erect-position, due to parallax, customer observes regarding for correction identifier 12
Line can fall the diverse location in transparent panel 20, thus user touches correction identifier 12 according to sight on transparent panel 20
Touch location is also different.Therefore, touch location during identifier 12 is corrected according to selection, control module 400 can calculate
Go out the height of sighting line (i.e. the eye position of customer) and erect-position of current customer, and then according to each height of sighting line prestored and often
The corresponding relation of corresponding touch area of the individual mesa region on transparent panel 20, sets Petting Area corresponding to each mesa region
Domain, that is, it is the touch area according to corresponding to the visual line of sight of customer setting each mesa region, may be such that the setting of touch area
The height and erect-position of customer is adapted to, consequently facilitating customer carries out touch selection.
In the present embodiment, correction identifier 12 is the less point of an area, thus the corresponding area on transparent panel 20
Domain is also only a touch point.That is, the eyes of customer should be in transparent panel positioned at correction identifier 12 with customer
In the sight that the line of 20 touch point is formed.In the case that the distance of each customer's relative transparent panel 20 is fixed
(for example each customer is 10cm from the horizontal range for blocking section 21 of transparent panel 20), can be according to relative transparent panel 20
Distance and the position of touch point accurately calculate the eye position of customer.However, in a practical situation, customer is from transparent area
What the distance of plate 20 was not always fixed, some customers are closer to the distance, and some is then distant.Therefore, single touch is only relied on
The eyes that can only a little determine customer are touched on line of the correction identifier 12 with touch point, and can not definitely learn that customer arrives
Bottom is how far from transparent panel 20.Therefore, with a distance from order to determine customer from transparent panel 20, can be intersected based on two lines
The unique principle of intersection point, the shape for correcting identifier 12 is adjusted.Preferably, correction identifier 12 comprises at least a line
Section, customer correspond to the position of line segment on transparent panel 20, tail end are slid into from the head end of line segment.Correct the head end of identifier 12
Corresponding with touch starting point of the customer on transparent panel 20, touch terminal of the tail end with customer on transparent panel 20 is corresponding.
In sliding process, the movement of the sight of customer remains that the slip with finger is consistent, and the eye position of customer is then all the time
Keep constant.Therefore, the company that touch starting point of the head end of setting correction identifier 12 with customer on transparent panel 20 is formed
Line is the first sight, set tail end and the customer of correction identifier 12 touching on transparent panel 20 line that terminal forms as
Second sight.First sight inherently meets at the opening position of customer's eyes with the second sight.Thus, two sights can be passed through
Intersection point uniquely determines the eye position of customer.In other words, the starting point position for controlling module 400 to be slided by obtaining customer's finger
Put, final position and distance, it is possible to uniquely determine the eye position of customer.Afterwards, eyes of the module 400 according to customer are controlled
Position (including eye-level and eyes from transparent panel 20 with a distance from), calculates each article corresponding to the customer of this height
11 touch area is simultaneously configured.Further, correction identifier 12 can also include prompt message, prompting customer need from
Head end slides into tail end.Prompt message can be that arrow, the correction identifier 12 drawn on correction identifier 12 is nearby or transparent
Prompt text on panel 20 or be to correct identifier 12 to include light source for lighting or flash successively from the beginning to the end etc..This
Outside, correction identifier 12 is also not necessarily limited to be line segment, can also be that other possess the geometry of certain length, pattern and word
With reference to etc., it is necessary to customer draws geometry, pattern etc., just represent that customer have selected correction identifier.In this process, by
Customer Yu touches multiple touch points, and the eye position of customer so can be accurately determined according to multiple touch points touched,
So as to be accurately determined touch area corresponding to each mesa region.
It is to be appreciated that the alleged correction identifier 12 of the present invention refers to that correcting identifier 12 is located at table top 10 on table top
On location, and and be not specific to correcting mark and know symbol 12 to be provided on the top surface of table top 10.In fact, correction identifier 12 is set
