Touch Sequence

A touch sequence is literally a command given to the system by a series of separate touches on a haptic responsive surface. If the surface is multi touch or capable of differentiating different parts of the finger by the type of touch, then multiple fingers or nails and knuckles may be used to increase the number of sequences with ease, and with a minimal learning curve for the user.

The first touch opens up an invisible menu of a sort – it primes the system to expect the second touch. If the second touch is not one of the acceptable options, or no second touch is forthcoming, the system acknowledges the initial gesture was not a command, and does not process it further.

Touch sequences thus allow natural hand and finger movements to be used inside the system as well as a command interface. It means the avatar hands and fingers can be controlled by the user's hand and finger movements as well as operating the touchpad – also allowing virtual touchpads to be used in the same way as physical ones.

For example, the user taps the pad, and then spreads their fingers in a letterbox shape across the pad. This is two touch commands. The first to get the system's attention, the second to zoom in on the point touched – the same system as Microsoft Surface uses, coincidentally. If the second gesture did not immediately follow the first – there was a tap but no command how to modify that tap, then the user did not intend to tap the surface, and the system silently cancels the command and processes the tap in another way – as avatar finger movement for example.

Haptics: Texture
Haptics is the study of the sense of touch. There are many parts to touch, and five different types of touch nerve in the nervous system. Here, we look at what goes into detecting texture, how the nerves work, and some initial attempts to interface with them for VR.

Animation: Gait and movement differs according to wealth
A look at using a pool of sequence files and the socio-economic status of an NPC, to create a set of sequence files for their avatar that makes their behaviour both unique and believable.

Haptics: Pressure
Haptics is the study of the sense of touch. Touch has many parts, but the most basic, the most fundamental of all, is that of pressure.

Visual Pathways the same, With or Without Eyes
A surprising find that pure touch-based sense organisms like hydras and jellyfish are capable of detecting changes in light levels in localised areas, strongly suggests that sight developed as part of the touch sense - and that some form of sight sensor is ideal when proprioception is not workable.

Woman with bionic arm regains sense of touch
The art of prosthetics has moved forwards once more, and Claudia Mitchell, who lost her arm in a motorcycle accident and became the first woman to be fitted with a bionic arm has now become the first woman to be fitted with an artificial arm ? same arm ? that returns a sense of touch to her nervous system.
