I created this to help me debug the two navigation techniques that I am using to get the set of countries that lay in a given direction. One is navigation by the rhumb line or compass heading and the other is using the great circle path as the trajectory.
When using rhumb line method the navigator sets a certain heading say 30 degrees and continues to head in that direction.
Whereas a great circle provides the shortest possible path between any two points but requires the navigator to constantly correct the heading. This makes navigating by great circle a lot more complicated than rhumb line method. Great circles are
Wikipedia entries on the two methods-
Rhumb Line
In navigation, a rhumb line (or loxodrome) is a line crossing all meridians at the same angle, i.e. a path of constant bearing. It is obviously easier to manually steer than the constantly changing heading of the shorter great circle route.
Great Circles
The great circle on the spherical surface is the path with the smallest curvature, and, hence, an arc (an orthodrome) is the shortest path between two points on the surface. The distance between any two points on a sphere is known as the great-circle distance. The great-circle route is the shortest path between two points on a sphere; however, if one were to travel along such a route, it would be difficult to manually steer as the heading would constantly be changing (except in the case of due north, south, or along the equator).

Two oscillators – SinOsc and TriOsc (triangle) at 200 and 300Hz
A sin and triangle oscillator with 200hz and 400hz base freq are multiplied in the following intervals 1,2,3,5,8,12 at 0.25 second intervals
A sin and triangle oscillator at these 1,2,3,5,8,12 intervals multiplied by their fundamental frequencies in sucession
Three triangle oscillators with 290hz and 300hz and 45hz base freq are multiplied by the following intervals 1,2,3,5,8 in 60ms intervals
64 sin waves at intervals 1,2,3,5,8,13,21,34 multipled by 21
60 sin waves at random freq between 200 and 240hz
60 sin waves at random freq between 200 and 2000hz

About the thesis · posted by vaibhav bhawsar 251 days ago
Area of enquiry
Re-appropriating the magnetic compass to show directions that are not cardinal but indicators of emotional, economic states. Creating new kinds of directions that a device could help you point to and explore.
Why do we need such a device
Most navigation devices in the past (compass,sextant) opened a new territory which one could move towards, explore and discover. When the compass points north it points towards a direction and not ‘a location’ or point. But in contemporary navigation devices, such as the GPS ,an absolute co-ordinate system, like ones latitude and longitude on a imaginary grid is given utmost importance. The GPS is extremely efficient and in this efficiency we loose a lot of richness of contexts due to the absence of the act of exploration. When we use a GPS, often its about getting from point A to B. While when we use a compass its still about getting from A to B but the journey in between those points is also important.
In brief I am interested in pointing devices that are fuzzy, vague and tacit and not in devices that are exact, precise or ingrained in a grid of x and y coordinates.
