TiX Tecnologia Assistiva – One Switch Games

Black background and column of coloured diamonds, each numbered for scoring. A yellow thick line falls from the top of the screen at 45 degree angles.

A batch of one-switch games, curated at TiX Technologia Assisstiva. Some may find them a challenge due to the timing required, but a challenge that could be fun. The website is in Portuguese, but some browsers (eg Chrome) offer a translation facility.

Arctic Pong: Slippery game of bouncing between two rubber bands, avoiding the Polar Bears. Requires fast taps and timing to play well.

Chef Jump: Jump to avoid flying chopping knives. Double-tap to jump higher. Fast taps and reactions needed most of the time.

Guns and Bottles: A lower pressure game. Bottles encircle your gun. Shoot them with your limited ammo. Requires accurate shots, but you can take as long as you like to fire.

Knife Smash: Throw your dagger at a rotating wheel filled with fruit (good) and weapons (bad – don’t hit them). As with Guns and Bottles, take as long as you like before pressing your button.

Perfect Fall: A basketball game based on Tower Bloxxx. Drop a ball into a hoop. Take as long as you like, but expect to miss a lot.

Zig-Zag line: Try to touch coloured diamonds the same as your line, and avoid all the others.

All play via left-click or touch. They also have some simple mouse games and an interesting accessibility controller. This “Teclado-mouse Inteligente” has nine main buttons with unique colour and symbol. This can be used as a mouse and as a fully fledged keyboard.

Jabberwocky (by Swiftable) is a free utility for Android phones and tablets enabling them to be used with head movement alone, tracked by the “selfie” camera.

Moving the on-screen cursor is by moving your head. Open and close your mouth quickly to tap. Open your mouth and move your head to swipe/drag.

Shaking your head left to right (as if saying “no” disables / enables the on-screen cursor. This could be useful if watching a film. It also helps to centre the cursor.

If the user is able, they can use Jabberwocky alongside other input methods (such as a mouse or switch interface).

It can be easier to use head-tracking with a mount to steady your camera or tablet device, and a fairly well lit area. I’ve found it smooth and responsive, and it could be a suitable option for playing lower pressure point and click type games, such as Angry Birds and Candy Crush as well as other low-speed activities.

Download Jabberwocky via the Google Play store.

PC and Apple iOS alternatives: Of note, head-tracking is also possible with a very recent iPhone or iPad Pro (one with Face ID / “TrueDepth” selfie cameras). Apple’s solution takes more steps to set up and felt less responsive in use. It could still be very useful though if you have this equipment. Some PC methods include Camera Mouse, Kinesic Mouse and more.

Sony UK are currently asking for help with their accessibility research in 2020. This from a Twitter post from Mark Friend:

“Want to help PlayStation with our accessibility research in 2020? We’ve got some pretty exciting projects in the works, and we’re looking for gamers with a wide variety of conditions and requirements to sign up to our mailing list.

The projects on offer are linked to some of the barriers you may be facing, and also if you’re able to get to their Oxford Street “client test-labs” or would need to do this from home only. That can be done via telephone or web conference.

Sony have announced an add on to their DualShock 4 joypad (the standard controller for a PS4). Called the Dualshock 4 Back Button Attachment, it adds two programmable back buttons and a round all-in-one display/button to help users set it up.

Reportedly, there are three profiles you can quickly swap between. These consist of a choice from 16 controls (d-pad, shapes, shoulder-buttons and perhaps L3, R3, Options and Touch-click). It seems the left-stick and right-stick directions won’t be available to apply to these buttons.

Due out in late January, in the US for $29.99 at least. Playstation Europe also promoting this, so a good sign for a broader release around the world.

This kind of thing can be very useful for people unable to reach all the controls comfortably who can reach the back of the controller well.

Alternatives: There are a number of other methods like this available. These include all-in-one custom controllers from Scuf Gaming. Also the Xbox One Strikepack Eliminator and PS4 Strikepack FPS Dominator adapters.

A free booklet on games that are possible to play using a single joystick and two buttons with a special Game Control Mixer adapter has been released by OneSwitch.org.uk.

Download: GCM 1 Stick 2 Buttons Booklet download (can be viewed direct from the link, but best downloaded and seen with a PDF viewer if you can). The video below is another way to view the booklet.

The GCM system enables far more games to be played, thanks to a special SHIFT feature. This enables the joysticks to be changed at any time to one of 24 modes amongst other features. More on this here and in the last video below.

Google’s Stadia has just been launched. It’s a streaming service, that allows you to play games through your internet connection without the need for a console. 

This tends to need an extremely fast internet connection to get really smooth high quality sound and graphics. Without this, things will sometimes get blurry, sloshy and at times stuttery. The upside for some is that all the games are in one place with no need to update software or keep upgrading your computer/console.
