Inputs of Interest: The OrbiTouch Keyless Keyboard and Mouse

Source: Hack a Day

Article note: Aw, man, I was hoping someone did a teardown. I've been super curious what the switch mechanism (8 switches? an analog stick?) in those things is for years, but not $300 curious.

I can’t remember how exactly I came across the OrbiTouch keyboard, but it’s been on my list to clack about for a long time. Launched in 2003, the OrbiTouch is a keyboard and mouse in one. It’s designed for people who can’t keyboard regularly, or simply want a different kind of experience.

The OrbiTouch was conceived of by a PhD student who started to experience carpal tunnel while writing papers. He spent fifteen years developing the OrbiTouch and found that it could assist many people who have various upper body deficiencies. So, how does it work?

It’s Like Playing Air Hockey with Both Hands

To use this keyboard, you put both hands on the sliders and move them around. They are identical eight-way joysticks or D-pads, essentially. The grips sort of resemble a mouse and have what looks like a special resting place for your pinky.

One slider points to groups of letters, numbers, and special characters, and the other chooses a color from a special OrbiTouch rainbow. Pink includes things like parentheses and their cousins along with tilde, colon and semi-colon. Black is for the modifiers like Tab, Alt, Ctrl, Shift, and Backspace. These special characters and modifiers aren’t shown on the hieroglyphs slider, you just have to keep the guide handy until you memorize the placement of everything around the circle.

The alphabet is divided up into groups of five letters which are color-coded in rainbow order that starts with orange, because red is reserved for the F keys. So for instance, A is orange, B is yellow, C is green, D is blue, E is purple, then it starts back over with F at orange. If you wanted to type cab, for instance, you would start by moving the hieroglyph slider to the first alphabet group and the color slider to green.

Slide Along the Rainbow

The interesting thing about this keyboard and this particular word is that all the letters for cab are in the first group. The keyboard will let you keep one of the sliders in place if you have repeated colors or letter groups, so you can keep the alpha slider in place and just move the rainbow slider around from green to orange to yellow to spell cab. Let’s watch it type ‘Hackaday’ over and over:

Every letter, number, and special character has an equivalent directional pair that may or may not be easy to memorize.  According to the FAQ, the maximum output you can expect from this thing is 30-40WPM. Although it is a combination keyboard and mouse, if you play any games that are more serious than say, Minesweeper,
forget about it. You’ll have to keep switching between keyboard and mouse mode, and it’s a whole thing, and you’re gonna die really quickly.

I think the color code is a great idea, but if you’re colorblind, it’s likely not going to be the keyboard for you. Also, you would have to have the use of both hands and a pretty good amount of coordination to be able to drive this keyboard/mouse hybrid creature. On the plus side, every gesture requires equal force, which is fairly low.

conclusion

Apparently this keyboard rates highly with autistic people because of the alphabetically rainbow-tastic way that the inputs are laid out. Those aesthetic choices are definitely a high point in my book. I think it’s neat that it’s so totally different from any other keyboard. It looks fun to try, at least for little while. Though I can’t imagine typing an entire Hackaday article on one, it looks way more fun to learn than Dvorak. I might buy one someday, but the OrbiTouch is a touch on the expensive side at $399, or you can pick them up used for around $200. They were actually sold out of both the black-and-white versions on the OrbiTouch website at the time of this writing, but there are a few out there on the electronic bay.

So is this keyboard really assistive technology? It kind of depends on your level of functioning. If typing hurts, but you still need to do it, this could be your saving grace. All things considered, I would think that all the joystick motion would aggravate wrist issues or even cause them, but since I haven’t tried actually tried one out, I can’t say for sure. Have any of you tried one?

No, Microsoft is not rebasing Windows to Linux

Source: Hacker News

Article note: It was such a weird rumor, the NT kernel is _fucking great_ in a lot of ways. The Windows userland has never been anything particularly special, and we're getting WSL so we can have a UNIX userland hosted (...much like the way Domain/OS could virtually host various UNIXes).

AMD Is in Advanced Talks to Buy Xilinx

Source: Hacker News

Article note: I guess Intel bought Altera so AMD feels the need to own a top-tier FPGA vendor as well? Xilinx did make a bunch of HyperTransport-compatible FPGA modules back when that was a thing, so perhaps they have an established working relationship they plan to exploit?

AMD Ryzen 5000 and Zen 3 on Nov 5th: +19% IPC, Claims Best Gaming CPU

Source: AnandTech Articles

Article note: AMD is still killin' it. Those look impressive and competitively priced, and are months ahead of Intel's planned next gen desktop parts.

Dr. Lisa Su, the CEO of AMD, has today announced the company’s next generation mainstream Ryzen processor. The new family, known as the Ryzen 5000 series, includes four parts and supports up to sixteen cores. The key element of the new product is the core design, with AMD’s latest Zen 3 microarchitecture, promising a 19% raw increase in performance-per-clock, well above recent generational improvements. The new processors are socket-compatible with existing 500-series motherboards, and will be available at retail from November 5th. AMD is putting a clear marker in the sand, calling one of its halo products as ‘The World’s Best Gaming CPU’.  We have details.

IBM to split into two companies by end of 2021

Source: Ars Technica

Article note: Whut. All the "younger" big old players in computing have had ignominious deaths (Sun, SGI, etc.) as they crumbled. HP has disassociated into divisions that make _some_ sense. Etc. But here goes IBM, the biggest and oldest of the surviving computing institutions, on another decade of "No apparent direction." They mismanaged their consumer-facing divisions (everything about small systems...) to death in the 90s and 2000s and divested, and now appear to be flailing the same way at everything. What I can't tell from the announcement is where their technically interesting parts (POWER, surviving mainframe industries, Fabs, etc.) will land.

IBM announced this morning that the company would be spinning off some of its lower-margin lines of business into a new company and focusing on higher-margin cloud services. During an investor call, CEO Arvind Krishna acknowledged that the move was a "significant shift" in how IBM will work, but he positioned it as the latest in a decades-long series of strategic divestments.

"We divested networking back in the '90s, we divested PCs back in the 2000s, we divested semiconductors about five years ago because all of them didn’t necessarily play into the integrated value proposition," he said. Krishna became CEO in April 2020, replacing former CEO Ginni Rometty (who is now IBM's executive chairman), but the spin-off is the capstone of a multi-year effort to apply some kind of focus to the company's sprawling business model.

Cloudy with a chance of hitting the quarterly guidance

The new spin-off doesn't have a formal name yet and is referred to as "NewCo" in IBM's marketing and investor relations material. Under the spin-off plan, the press release claims IBM "will focus on its open hybrid cloud platform, which represents a $1 trillion market opportunity," while NewCo "will immediately be the world’s leading managed infrastructure services provider." (This is because NewCo will start life owning the entirety of IBM Global Technology Services' existing managed infrastructure clients, which means about 4,600 accounts, including about 75 percent of the Fortune 100.)

The Supreme Court is taking on Google and Oracle one last time

Source: OSNews

Article note: There is the summary I was looking for.

Ten years after Oracle first sued Google over the code in the Android platform, the two tech giants are finally facing off in the Supreme Court. Since then, there have been three trials and two appeals. Billions of dollars are at stake; many millions have been likely spent on a parade of seasoned litigators, expert witnesses, and bizarre trial exhibits intended to explain programming to non-technical juries. All this may be coming to an anticlimactic close on Wednesday morning, with a teleconference Supreme Court oral argument in the middle of a pandemic.

Google must win this case. Not because Google somehow deserves it, but because Oracle and its CEO are the scum of the earth dead set on destroying the very foundations of programming.

I built a lay-down desk

Source: Hacker News

Article note: I still have the articulating bedframe that was my bed+recliner in my studio in my office at home, because "conformantly reclined with a laptop" really is a pretty good way to do some kinds of work. Quite a bit of what I do lately requires my double monitor + work area with overhead camera setup, which gives me limited ability to change my position (and that setup isn't readily adapted to standing), but I still mix it up when I can. I'm convinced the problem with almost all "ergonomic" solutions is basically that it's bad to spend so much time in any one position, so varying your shit is the real key. That's also part of my attraction to split keyboards and such - I can rearrange myself and keep working.
