in some embodiments of the present invention , as seen in fig1 and 2 , a pointing device 100 is adapted to point an indicator 101 in a compass direction coupled with a look down angle . as seen in fig1 , an observer 106 is seen in a conceptual illustration at a point 103 on the surface of the earth . the pointing device 101 is adapted such that the indicator may be set point at different location on the earth 104 , as well as a person 105 at the different location 104 . as seen in fig2 , the pointing device 100 has a pointer 125 which has an arrow indicator , or pointer , 101 . the base 121 of the device 100 may have degree markers 123 which may be used to indicate compass direction . the degree markers 123 may be of a 0 - 360 degree scale . the base 121 is has a bottom surface 133 which is adapted to be placed upon a surface when the device is used , although the device 100 could also be held or otherwise suspended . in some embodiments , a compass 120 is embedded into the base 121 , and may be used to allow for the alignment of the degree markers 123 on the base 121 to magnetic north . as seen if fig1 , if a user desires to point an indicator from a first point on the earth to a second point on the earth , especially if the second point is at distance , the indicator may be set by using an offset from north in a rotation plane , which may be referred to as a rotation angle , and then by selecting a look down angle . setting an indicator using the rotation angle and the look down angle thus provides the information necessary to achieve the desired pointing direction . in some embodiments , a rotating partial disk , or sail 122 , is adapted to reside on the base 121 . the sail 122 may be pinned to the top surface of the base 121 such that it is perpendicular to the base 121 , and such that the sail 122 may be rotated around a center point 136 of the base 121 . the sail 122 may have degree markers 124 on its periphery , which may be from 0 to 90 degrees . a directional indicator 125 with a pointer 101 is adapted to be rotated on the sail such that the pointer may point down at a selected look down angle . the look down angle may be set using the degree markers 124 on the sail , and may be read using a window 126 in the directional indicator 125 . the directional indicator 125 may be pinned to the sail 122 to allow for movement along a range of look down angles . fig3 is an exploded view of a pointing device 100 according to some embodiments of the present invention . the base 121 is adapted to be placed upon a flat surface when the pointing device 100 is in use . a compass 120 may be inserted into a recess in the base 121 . a base hole 130 is adapted to receive a base pin 131 , which in turn receives a hole in the bottom of the sail 122 . the sail 122 may have a marker 127 adapted to align the rotatable sail with a direction on the base . the directional indicator 125 may be rotatably pinned to the sail 122 with a sail pin 132 . the sail 122 may have recesses 126 in its bottom surface to allow for clearance over the compass 120 , or for ease of rotation , or for other reasons . in use , the base may first be aligned with the compass to set the north indicator on the base to be aligned with the north of the compass . next , the sail may be rotated to a pre - selected rotation angle by aligning the marker 127 with the corresponding degree marker on the base . then , the directional indicator may be rotated to an angle corresponding to a pre - selected look down angle . if a user selects a pre - selected look out angle and look down angle to indicate the direction from the user &# 39 ; s location to a selected second point on the earth , and then orients the pointing device as described above , the pointer 101 will be pointing to the selected second point . the pointing device may be used to set the pointer towards the location of a city of interest , of religious significance , or of other significance . the pointer will point towards the selected location directly , in the shortest line , as opposed to a direction along the surface of the earth at the user &# 39 ; s location . in another scenario , the user may want to point the pointer in the direction of a person , such as a loved one , that is at another location . the pointing device may be used to point as a reminder to the user where a selected location is . the pointing device may be used to remind the user of the location of a loved one . in order to set the pointer properly , the user must know the rotation and look down angles associated with the selected second location with regard to the user &# 39 ; s location . in some embodiments , as seen in fig4 , a lookup table 200 may be used . the table may include locations of the user in a column , and then a list of second locations across a top row . the rotation and look down angles are then seen in the location where the start location in the first column intersects with the second location in the top row . in the example of a lookup table as seen in fig4 , each intersection point between a start location in the first column and a second location across the top row is seen with two numbers together . the first number represents the look down angle , and the second number represents the rotation angle . these two numbers represent the values for the rotation and look down angles that a user would set the pointing device to in order to point at the selected second location from the user &# 39 ; s location . in some embodiments of the present invention , as seen in fig5 , an electronic computing device 150 may be used to determine the look out angle and the look down angle . the user &# 39 ; s location and the location towards which the pointer is to be pointed may be entered into the electronic computing device 150 . the inputs may be put in using city data , or latitude and longitude . in some embodiments , the electronic computing device 150 may contain code for determining the angles , and the code may be contained on a computer readable medium . in some embodiments , the electronic computing device 150 may be connected to an electronic system 151 via a global area computer network 152 , such as the internet . the electronic system may contain a computer program product containing code for determining a rotation angle and a look down angle as described above . the previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure . various modifications to the disclosure will be readily apparent to those skilled in the art , and the generic principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure . thus , the disclosure is not intended to be limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein .
