Approximating Perceptual Crossing to a usable Game
Interaction with static
Interaction with shadow
Interaction with partner
Resources
- 1 minute exploration time
- single click
Parallel decisions
- engage or not
- click or not
Errors
- Type I: mistake an object for the partner
- Type II: mistake partner for an object
Bob
Alice
Building the model
1. Modelling an encounter
Alice comes across Bob
| Bob \ Alice | Interact less | Interact more |
| Interact less | ρLL | ρML |
| Interact more | ρLM | ρMM |
(1-α) ρLL + α ρLM
(1-α) ρML + α ρMM
