Perceived Weight of Mediated Reality Sticks.
IEEE Transactions on Visualization and Computer Graphics
|September 4, 2025
Summary
Mediated reality alters visual perception of physical objects. Users perceived longer sticks as lighter and recognized objects with missing parts as continuous, impacting perceived weight and center of gravity.
Area of Science:
- Human-Computer Interaction
- Perceptual Psychology
- Virtual and Augmented Reality
Background:
- Mediated reality merges augmented reality (AR) and diminished reality (DR) for visual object modification.
- Physical properties remain unchanged, but perception differs upon interaction.
Purpose of the Study:
- Investigate user perception of weight and center of gravity (COG) with mediated reality objects.
- Explore how visual alterations affect tactile perception of physical properties.
Main Methods:
- Two user studies ($N=10$) with substudies were conducted.
- Participants interacted with mediated reality sticks of varying lengths and with missing portions.
- Reported perceived weight and center of gravity were collected.
Main Results:
- Perceived weight was inversely related to the visual length of mediated reality sticks.
- Sticks with visually missing portions were perceived as continuous, retaining original weight and COG.
- A relationship between inertia, reported COG, and perceived weight in dynamic touch was formulated.
Conclusions:
- Visual perception in mediated reality significantly influences the tactile perception of physical object properties.
- Object continuity is maintained visually, affecting weight and COG perception.
- Findings contribute to understanding dynamic touch and mediated reality interactions.

True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.

01:28Apparent Weight and the Earth's Rotation
3.7K
Since all objects on the Earth's surface move through a circle every 24 hours, there must be a net centripetal force on each object, directed towards the center of that circle. The points of the north and south poles are the only exception to this rule.
For an object on the Earth's equator, the net centripetal force that accounts for its rotation is the Earth's pull towards its center, or the weight minus the normal force that prevents it from piercing into the Earth's surface....

When an object is dropped, it accelerates toward the center of the Earth. If the net external force on the object is its weight, it is said to be in free fall; that is, the only force acting on the object is gravity. Galileo was instrumental in showing that, in the absence of air resistance, all objects fall with the same acceleration g. However, when objects on the Earth fall downward, they are never truly in free fall, because there is always some upward resistance force from the air acting...

01:13Cable Subjected to Its Own Weight

Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

01:19Mass and Weight
12.2K
Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

01:20Variation in Acceleration due to Gravity near the Earth's Surface
2.5K
An object's apparent weight is its weight measured by a spring balance at its location. It is different from its true weight, the force with which the Earth pulls it, because of the Earth's rotation. Mathematically, an object's apparent weight equals its true weight minus the centripetal force that keeps it in a circular motion along with the Earth's surface every 24 hours.
The difference between the true and apparent weights is proportional to the square of the Earth's...
