European Journal of Neuroscience, Volume 61, Issue 7, April 2025.Moving objects touch successive skin locations, providing spatial information. When a brush sweeps along the skin but rapidly accelerates to skip a patch in the middle, it creates deceptive temporal continuity between skin regions before and after the gap. This acceleration‐induced continuity causes spatial distortion: the untouched region perceptually

Support Vector Regression for Mobile Target Localization in Indoor Environments
Sensors, 2022 Trilateration-based target localization using received signal strength (RSS) in a wireless sensor network (WSN) generally yields inaccurate location estimates due to high fluctuations in RSS measurements in indoor environments. Improving the localization

Ecological Solutions and Evidence, Volume 6, Issue 1, January–March 2025.This field study aimed to test the performance of a compact/handheld surveyor‐grade GNSS receiver, functioning as an external sensor (A), compared to smartphones' inbuilt GNSS receivers. The surveyor‐grade GNSS (black) had significantly better absolute horizontal accuracy (B).

Proximity-Based Adaptive Indoor Positioning Method Using Received Signal Strength Indicator
Applied SciencesIn this paper, we propose a proximity-based adaptive positioning algorithm to address the challenge of positioning errors in indoor localization based on RSSI (received signal strength indicator). When positioning by trilateration, if a receiver is close

A Multilevel Optimised Algorithm for UWB Positioning in Indoor Environment
IET Communications, Volume 19, Issue 1, January/December 2025.In ultra‐wideband indoor positioning systems, complex environmental factors such as multipath effects, occlusions, and non‐line‐of‐sight propagation often leads to decreased positioning accuracy and limited system robustness. To address this issue, this paper proposes a multilevel optimised estimation algorithm that integrates Particle Filtering with ...
