Mobile+phone.+Phoebe.

When designing a mobile phone it is important to consider the all aspects to do with the measurments of a human body and how they relate to a mobile phone.
 * __Anthropometrics of a mobile phone__**

Aspects to consider would be:
 * **Hand size** - A phone needs to fit its customer, therefore it is designed for the 95th percentile to ensure the majority of people can use the phone.
 * **Finger dimensions -**
 * **Thumb size -**

__**Design factor related to ease of use that has compromised the use of human factors**__

Sometimes the shape/size of the phone can compromise the use. If the phone is a too big or too small people don't want to use it. Also the shape of the phone for example this phone shaped as a car it is less likely to be used by people.

__**Psychological human factors data**__

These include **colour**, **sound**, **light** and **texture** of the phone.


 * **Colour ** - By making a phone accessable in multiple colours more people will buy it. Although not all phones come in all different colours. There are certain colours such as silver that most people will like for their phone because it is aesthetically pleasing.
 * Sound - The sounds that the phone makes need to alert the customer for example the ring tone of the phone. They want something they can hear easily. Therefore the volume on the phone should be loud. It also needs to the the ability to be on silent for when you dont want to be disturbed by a noisy phone.
 * **Light ** - The screen needs to be light enough for people to see everything easily but at the same time it does not want to be too bright that it hurts the eyes of the customer. Most phones will be able to change the brightness to best suit the customer.
 * **Texture** - The texture of a phone is important because it needs to feel comfortable and nice to hold. A phone will usually be smooth and have a glossy finish this is because it will draw people to it. Making them want to use it more.
