The 2023 Game developers Conference (Game Developers Conference, or GDC) is under way.

GDC is the largest game developer conference in the world, known as rdquo;, the weather vane of ldquo; game technology, which brings together various cutting-edge game technology discussions every year.

Tencent Games shows a special technical application at this conference:The ldquo; vibration & rdquo; technology in the "Game for Peace" mobile game is provided to the visually impaired group.

This vibration technique is called tactile feedback. In order to create the game on the mobile end & ldquo; pseudo-physical sense & rdquoThe "Game for Peace" team matched exclusive vibration sound effects for more than 200 characters, vehicles and weapons in the game by optimizing audio and tactile algorithms.

One day, the team had a whim: can this technology be used in barrier-free areas? Let their mobile phone & ldquo; move & rdquo; up. There are nearly 17 million visually impaired people in China, as well as a large number of elderly people with decreased eyesight, which makes daily communication and travel inconvenient due to eyesight.

This technology was first applied in Sogou Input and Tencent Map.On mobile phones, visually impaired people used to be able to perceive only through sound, and this technology adds a-ldquo; vibration-rdquo; perception.

Turn on the vibration sound effect function of the input method, typing will trigger strong vibration, different key positions adapt to the corresponding vibration sound effect, deletion is a strong vibration reminder.Before can not see clearly, enter the password, press the wrong worry, press the right also worry-mdash;— this, just rest assured.

In order to meet the needs of the visually impaired, we also combine tactile feedback with anchor scheme. It's like installing a touchscreen phone with a ldquo; keyboard & rdquo;:, for example, if you take the number 5 as the center & the ldquo; bulge & the anchor of rdquo;, you can distinguish different numbers by different vibration frequencies.

Tencent Map also provides different lengths of vibration sound effects for navigation, bus stops and passing stations through vibration sound effects. If you go the wrong way, ldquo; will listen to the position and rdquo;, will be adjusted back in the right direction.

In order to better make the visually impaired feel better, Tencent and partners have set up a standards working group to promote the development of technical standards to ensure that visually impaired people experience consistent vibration effects.

In addition to the application of input method and map, Tencent also authorizes the relevant patents that haptic feedback technology has produced in the barrier-free field to public welfare projects of the whole society in the form of open license.
