Ho chiesto se fosse cieco solamente perché nei film lo e', e dato che tutti parlate di nascondervi sotto i tavoli o negli armadietti mi chiedevo a cosa servisse se tanto lui non puo' vedervi. Tanto vale stare fermi al centro della stanza, no?
Ho cercato un po' ieri sera e in realtà il fatto che siano ciechi o meno è dibatutto:
http://en.wikipedia.org/wiki/Alien_%28creature_in_Alien_franchise%29Qui si parla del fatto che inizialmente, nei prototipi di Giger, l'alieno avesse gli occhi:
Poi Scott l'ha preferito senza.
Nel terzo film c'è anche il point of view dell'alien, che però si potrebbe considerare una scelta registica e non la visuale reale dell'alieno.
A me sembra di capire che siano capaci di 'vedere' in senso stretto ( escludo quindi l'ecolocazione) ma ci sta che non ci vedano benissimo da lontano e se si rimane fermi può darsi che non capisca cosa ha di fronte.
Farò qualche tentativo per capirlo.
Se così fosse, mi pare strano che nessuna guida inizi con questo suggerimento a caratteri cubitali:
http://www.ign.com/wikis/alien-isolation/Best_Ways_to_Escape_the_Alien(a onor del vero qui esplicitano che a livello facile ci si può accucciare sotto il tavolo anche se l'alieno ci sta guardando direttamente, perché il più delle volte non ci vedrà... il che dovrebbe però significare che a normal ci vedrebbe).
Certo se l'alieno è completamente cieco da lontano (se non produciamo rumori) il gioco cambia radicalmente.
PS: non credo che l'alieno abbia un buon olfatto. Non rispetto ai nostri animali terrestri (altrimenti hai voglia di nasconderti..)
Ho trovato questa lettura sui sensi dell'alieno ma ora non ho tempo per leggerla ^^
Here is a good read on xeno perception:
There are several striking features that stand out when examining the adult form of I. raptus. The first, and perhaps the most prominent, is the head. Its seemingly disproportionate size indicates that there is a structural reason for this development. Its size could be due to an enlarged brain. This would not necessarily indicate a greater intelligence, but perhaps a more complex/sensitive brain that is designed to work not only as a means of assessing and thinking, but as an organ designed for extremely accurate sensing abilities. The idea of an enlarged brain has recently fallen under much speculation and debate within the scientific community - the idea as to whether or not the cranium is strictly for housing a brain may not be accurate.
A great many researchers believe that the cranium houses only a moderately sized brain - perhaps only occupying one quarter to one third of the head. The remaining portions of the cranium are believed to house complex nerve centers that aid in collecting and processing sensory acquired stimuli, pheromone glands, an array of communicative emitters, adrenal glands, and a compression chamber for use when striking with the secondary jaws. It is the general belief that the majority of the cranium's volume is geared towards the processing and interpretation of sensory acquired stimuli as well as the emission of various signals designed for the purpose of communication. Aside from the maintenance of the hive structure, and tending to the producing Queen, the primary role of an adult is that of a forager - acquiring food and host material to further the hive. With such a specific role it would logically follow that the Alien would rely heavily on its senses for the location and acquisition of prey, and understanding it's environment. This being said it is then the general belief that the head represents the center of sensory reception and communication for the Alien. The working model for stimuli reception is as follows: The head is covered with pore-like receptors - each dedicated to a specific stimuli - Olfactory/biochemical reception (i.e. - pheromones), thermal detection, bioelectric detection, and auditory reception. The pores gradate from back to front, meaning that there is a higher concentration of sensory receptors at the domed anterior portion of the head as compared to the back. This gives I. raptus 360� lateral sensory ability, and approximately 180� vertically with the area of optimal overall clarity being at the front. It is estimated that the total range of optimal clarity is 100 degrees radiating 50� on either side of the center-front of the cranium laterally, as well as 70� radiating vertically from the same point. This then puts the remainder of stimuli within varying degrees of peripheral reception.
Next to the head it is believed that the hands and feet are responsible for the second largest amount of sensory input. The pads that cover potions of these extremities are believed to be the primary receptors of auditory vibration through substrate as well as additional biochemical reception. It is thought that the latter is designed for identification and recognition hive mates and pheromone trails.
The head may represent the center of sensory reception, but it also believed to the center of communicative emission. Going under the belief that I. raptus utilizes bioelectric radiation and ultrasonic emission as primary means of communication with a secondary means being biochemical the head becomes the focal point for the majority of this activity. It is not clear if ultrasonic emission as released via the mouth, or through pore-like emitters similar to those used in receiving stimuli, but the current assumption is that it is produced within the head and emitted in a radiating pattern from the surface of the cranium. The same principle also applied to the emission and radiation of bioelectric signals.
