# Fragerunde
|
# A few **questions** first
|
||||||
|
* Who here would consider themselves a **developer** ?
|
||||||

|
* Experience with **code editors / IDEs** ?
|
||||||
|
* **More comfortable** with editor than with other software ?
|
||||||
* Wer hat schon VR getestet?
|
* Does **text** just feel faster/more efficient at this point?
|
||||||
* Wie immersiv war die Erfahrung?
|
|
||||||
* Gab es haptisches Feedback?
|
|
||||||
* Wenn ja: wie wurde das implementiert?
|
|
||||||

# Was ist **haptisches Feedback** ?
|
# <div class="inline-img">  **Markdown**
|
||||||
|
## (It's everywhere - you've most likely dealt with it at least once)
|
||||||
|
```md
|
||||||
|
# Main title
|
||||||
|
## Heading 2 - You can make:
|
||||||
|
|
||||||
* Nutzer:innen bekommen eine **taktile Rückmeldung**
|
- *italic text*
|
||||||
* Kann **Immersion** weiter als "nur hören oder sehen" treiben
|
- **bold text**
|
||||||
* Informationen können sehr **unterschiedlich** sein (Vibration, Textur, Kraft, Wärme, ...)
|
- ~~strikethrough~~
|
||||||
* Beispiel: <box>Erzeugung von **Kräften** zur Simulation von Gewichten und Längen

# Nutzung der **Visual Dominance** [2]
|
# Why not write **presentations** as text ?
|
||||||
* **Alle Sinne** tragen zur gelebten Erfahrung bei einer Simulation bei
|
## <div class="inline-img"> Introducing:  (Yuki Hattori)
|
||||||
* Bei Konflikten hat die **Sicht** bei der Informationsverarbeitung **Vorrang**
|
* Markdown presentation ecosystem
|
||||||
* Bedeutung für VR: <h3><box>Für eine realistische Wahrnehmung muss **nicht die gesamte Kraft** erzeugt <br> werden, sondern nur genug, um die **Sicht** zu **unterstützen**
|
* <span class="inline-img"> Comes as a  command line tool or a  VSCode editor extension
|
||||||
|
* Technically Just A Web Page:tm: $\implies$ can write HTML/CSS if you want to customize
|
||||||
|
* MarpX (Paolo Cunha) offers high quality ready-to-use themes
|
||||||
|
* If you know Markdown/HTML/CSS: <box>No need to learn (yet another) tool!

# **Hintergrund** des Papers
|
# **Collaborating** with others / keeping track of **versions** ?
|
||||||
* *Passive Haptic Feedback* (PHF): günstig und mobil, nicht sehr realistisch
|
> ## "Well surely the editor can't do ***that*** ", I hear you say
|
||||||
* *Active Haptic Feedback* (AHF): realistischer, weder günstig noch mobil
|
* All the presentations are **text-based** versions of a file tree
|
||||||
* $\implies$ ***Dynamic Passive Haptic Feedback* (DPHF)** als Mittelweg testen ?
|
* We need a tool to maintain **versions** of a text-based file tree...
|
||||||
* ### <box> 💡 Idee: Bewegung soll **kein direktes Feedback** sein, sondern den Controller so ändern, dass er **mehrere Gegenstände** darstellt
|
* <span class="inline-img"> Ever heard of  `git`?
|
||||||
|
* We already have a **tool** to collaborate on versions of text-based projects!

# **Hintergrund** des Papers
|
# How do we make sure data is **safe** from big companies?
|
||||||

|
- there *are* online platforms like GitHub for this (but: this defeats the whole purpose)
|
||||||
|
- it's 2026, and servers are pretty cheap
|
||||||
|
- you can set up your own infra in an afternoon

# **Shifty** als DPHF-Versuch
|
# One step further: hosting services on your own infrastructure
|
||||||
|
- I won't tell you how to set it up (plenty of guides online)
|

### Ziel: Gewicht nach oben bzw. unten bringen, um mehr bzw. weniger Kraft zu brauchen, um gehoben zu werden

# Erwartungen der Autoren
|
|
||||||
|
|
||||||
- "We expect [...] Shifty to increase the **realism** and **fun** compared to [PHF]."
|
|
||||||
- "[W]e expect the participants to favor Shifty's feedback and that **enhanced visualizations** [...] increase the perceived **realism** and **fun** for the user, while **minimizing the disturbing impact** [...]."
|
|
||||||
- "Regarding **exertion**, we expect [PHF] to require the least, and Shifty's dynamic feedback to be more physically demanding."
|
|
||||||
- "[W]e also expect **appropriate visualizations** to **compensate** for that to some degree, decreasing the perceived **exertion** compared to a standard visualization.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
Stimmt das? 🤔

# Experiment 2: **Ergebnisse**
|
|
||||||
- ✅ **<box>Realismus** und **<box>Spaß** sind höher bei Shifty als bei PHF
|
|
||||||
- ✅ Visiualisierungen minimieren die **<box>Beunruhigung**
|
|
||||||
- ✅ **<box>Anstrengung** ist höher bei Shifty als bei PHF
|
|
||||||
- ❓ Visualisierungen kompensieren (einigermaßen) die **<box>Anstrengung**
|
|
||||||
- Bisherige Ergebnisse zur **Visual Dominance** bestätigt

# Experiment 2: **Ergebnisse**
|
|
||||||
## Welche Variante liefert die beste Erfahrung?
|
|
||||||
|
|
||||||
* ### TL;DR: <box> Es hängt davon ab, welche Eigenschaft am wichtigsten ist
|
|
||||||
* **<box>Realismus**/**<box>am wenigsten beunruhigend**/**<box>Präferenz** $\implies$ `Skalierung`
|
|
||||||
* **<box>Spaß**/**<box>Präferenz** $\implies$ `hinter Rauch verstecken`
|
|
||||||
* **<box>Anstrengung** (Min.) $\implies$ `Base (nur PHF)` Wenn DPHF verwendet $\implies$ `Transparenz`
|
|
||||||
|
|
||||||

|
|
||||||
# Experiment 2: **Limitierungen**
|
|
||||||
* Auch nur $n=12$ Teilnehmenden
|
|
||||||
* Keine Unterscheidung zwischen physischen und mentalen **<box>Anstrengung** beim *exertion*
|
|
||||||
* Auch wenn kompensiert $\rightarrow$ **<box>Anstrengung** bleibt hoch
|
|
||||||
* Beispiel eines Hammers ist **begrenzt** (1-dimensionale, mit Shifty kompatible Anwendung)

# **Fazit**
|
|
||||||
|
|

<div class="multicolumn"><div>
|
|
||||||
|
|
||||||
## Vorteile
|
|
||||||
- **interessante Entwicklung**
|
|
||||||
- **Realismus** und **Spaß** werden bei **tragbaren Kosten** erhöht
|
|
||||||
|
|
||||||
</div><div>
|
|
||||||
|
|
||||||
## Nachteile
|
|
||||||
- nur ein **Forschungsprojekt**
|
|
||||||
- nur 1-dimensionales Trägheitsmoment (weit von AHF entfernt)
|
|
||||||
- **Anstrengung** soll berücksictigt werden
|
|
||||||
- Andere Aspekte des hapt. Feedbacks wie Textur und Form nicht geändert

# **Ausblick** der Studie
|
|
||||||
- Horizontale Implementierungen von Shifty testen, um **mehr Dimensionen** hinzuzufügen
|
|
||||||
- Weitere Forschung zur **Visual Dominance**, um Realismus zu erhöhen
|
|
||||||
- 2\. Experiment mit **komplexeren Formen** als Würfel wiederholen
|
|
||||||
- Einfluss von DPHF auf **Inputs** testen
|
|
||||||
- Erfahrung mit DPHF über **längere Zeitspannen** testen
