Design Example: Measuring Distance Between Two Points with Obstructions01:10

Design Example: Measuring Distance Between Two Points with Obstructions

280
When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...

Three-Dimensional Force System:Problem Solving01:30

Three-Dimensional Force System:Problem Solving

1.2K
A three-dimensional force system refers to a scenario in which three forces act simultaneously in three different directions. This type of problem is commonly encountered in physics and engineering, where it is necessary to calculate the resultant force on the system, which can then be used to predict or analyze the behavior of the object or structure under consideration.
To solve a three-dimensional force system, first resolve each force into its respective scalar components. Do this using...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.5K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Design Example: Traverse Angle Computations

231
Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Centroid of a Body: Problem Solving01:03

Centroid of a Body: Problem Solving

1.7K
The centroid of a body is a crucial concept in engineering and physics. Finding the centroid of a body can help determine its stability, its balance point, and even its design. In this context, consider a thin wire bent in the form of a quarter circular arc. Polar coordinates are used to calculate the centroid. The wire is first divided into small differential elements of a length equal to the radius multiplied by the differential angle.
The x-coordinates and y-coordinates of each element's...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

290
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Area of Science:

  • Computer Science
  • Robotics
  • Human-Computer Interaction

Background:

  • Existing indoor navigation systems often overlook individual user spatial needs and physical dimensions.
  • This oversight can lead to inadequate or uncomfortable movement space for users in real-world indoor environments.

Purpose of the Study:

  • To propose a novel human-oriented navigation approach that accounts for user dimensions and object interactions.
  • To establish comfortable navigable spaces by considering individual user needs and environmental constraints.

Main Methods:

  • Deriving object space (O-Space) based on user types (e.g., disabled/non-disabled) and functional space (F-Space) for indoor objects.
  • Calculating narrow gaps considering indoor obstacles (defined by O-Space), object F-Space, and stationary objects.
  • Establishing comfortable navigable space by excluding sealed spaces and narrow gaps.

Main Results:

  • The proposed method successfully generates comfortable navigable spaces and user-friendly paths.
  • Navigation users can move easily and without stress through the established comfortable spaces.
  • Demonstrated effectiveness in two indoor navigation case studies.

Conclusions:

  • The human-oriented approach significantly improves user experience in indoor navigation.
  • This method holds potential for enhancing navigation in unfamiliar environments and emergency situations.
  • Prioritizing user dimensions and interactions leads to more intuitive and comfortable indoor navigation systems.
