Distance-Gated 360-Degree Waypoint Views for Pedestrian Walks: Mapping Fused Step-Count and GNSS Distance onto Virtual Routes, with Walking-Triggered Auto-Close, Distance-Based Prefetch and Intro-plus-Loop Omnidirectional Video

A mobile walking system converts the distance a pedestrian actually walks, anywhere, into progress along a virtual route through an imaginary world. Walked distance is the larger of a GNSS (GPS) distance, filtered by reported accuracy, stillness speed and implausible jumps, and a pedometer distance (step count × stride length). Virtual waypoints (stops) are placed at fixed distances on the route. While walking, only a simple progress map is shown.

Abstract

Defensive publication / technical disclosure (prior art). A mobile walking system converts the distance a pedestrian actually walks, anywhere, into progress along a virtual route through an imaginary world. Walked distance is the larger of a GNSS (GPS) distance, filtered by reported accuracy, stillness speed and implausible jumps, and a pedometer distance (step count × stride length). Virtual waypoints (stops) are placed at fixed distances on the route. While walking, only a simple progress map is shown. When the fused distance passes a waypoint, a looping omnidirectional (360-degree, spherical, equirectangular) video of that place opens and is explored by device orientation (gyroscope look-around). If the user keeps walking, the immersive view closes automatically after a short further distance (10 m in the preferred embodiment), for pedestrian safety (distracted walking). Waypoint media is prefetched a set distance ahead (150 m). Videos may play an intro once and then loop from a marked loop-start time. Methods for producing seamless 360-degree loops by keyframed image-to-video generation, procedural particle and domain-warp layers, Gaussian-splat rendering and game-engine panoramic rendering are also described. This record contains two files: the English document (authoritative) and a Japanese translation of the same content (日本語訳を同じ記録に収録). The document gives preferred numeric values, alternative embodiments, claim-like statements and extensions so that the ideas are enabled and citable as prior art. Commercial embodiment: the SunPo iPhone app (Apple App Store, app ID 6789954864) at the time of publication. The licence covers the text and figures; the name "SunPo" is the author's product name. 要約(日本語) 携帯端末を用いた散歩システムであって、歩行者がどこで歩いても、実際に歩いた距離を架空の世界を通る仮想ルート上の進行に変換する。歩行距離は、GNSS(GPS)による距離(報告精度・静止速度・あり得ない跳躍で点を除外)と、歩数計による距離(歩数×歩幅)のうち大きい方とする。ルート上の決まった距離に仮想のウェイポイント(拠点)を置く。歩行中は簡単な進行地図だけを表示する。統合距離が拠点に達すると、その場所のループする全天球(360 度・正距円筒)映像が開き、端末の向き(ジャイロによる見回し)で見回せる。利用者が歩き続けると、歩きスマホ防止(歩行者の安全)のため、一定距離(好ましい実施形態では 10 m)で没入表示が自動で閉じる。拠点の映像は一定距離(150 m)手前で先読みする。映像はイントロを 1 回再生した後、印を付けたループ開始時刻から繰り返すことができる。キーフレームを指定した画像から動画への生成、手続き的な粒子とドメインワープの層、ガウシアンスプラットの描画、ゲームエンジンのパノラマ描画によって継ぎ目のない 360 度ループ映像を作る方法も記載する。
