Touch Sequence Navigation

Touch sequence navigation is a specific subset of touch sequences, concerned solely with moving the user's focal point around in a simulated environment. Like all touch sequences, it consists of a command given to the system by a series of separate touches on a touchscreen or touchpad. If the hardware supports multi-touch or differentiates touch by parts of the finger, so much the better. By using a touch sequence, the interface allows complex commands to be performed with minimal learning curve by the user.

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

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 navigate towards the point initially touched – to zoom towards it as it gets larger on the display. 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 initiates no movement.

This avoids the nightmare scenario for any interface – user confusion. If we just used a single touch to navigate, than any accidental pressure on the interface would whisk the user's point of view away to parts unknown. Instead, the two or three part sequence ensures that navigation remains intuitive, but is not triggered accidentally.

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.

Optical Machine Vision Navigation System Found in Flies
A study conducted to understand how flies and bees can navigate so precisely using just natural sunlight, has interesting implications for machine vision, and adding additional sense-based navigation systems to UAVs and UGVs without adding the weight or cost of any extra hardware.

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.
