Tactile Vest Gives Gamers a 4th Dimension

April 22, 2010 -

How do you think violent videogame critics would react to a Tactile Gaming Vest that allows players to physically feel in-game shootings and stabbings?

The vest was created by University of Pennsylvania graduate student Saurabh Palan as part of his course work for a mechanical engineering class called Haptic Interfaces for Virtual Environments and Teleoperation.

When hooked up to a game like Half-Life 2, the player is able to feel simulated gunshots, slashing by knives and blood flow from wounds. Feedback, according to Palan’s blog, is generated in the suit by a variety of “solenoids, eccentric-mass motors, and Peltier elements controlled by custom electronics and a personal computer.”

Hits on-screen also register on the appropriate part of the player’s vest and body.

More from Palan:

When the player gets shot in the game, the program will turn on the specific solenoid based on the position of gun shot in the game and also trigger the blood flow simulation process. The gun shot can be felt almost instantly as it occurs in the game.

Originally it was planned for the vest to also feature feedback representing physical attacks, such as punches and kicks, environmental temperatures and even concussive feedback from the impact of artillery, but available time only allotted for the inclusion of gunshots, knife wounds and blood flow. Another abandoned idea was to simulate a bullet’s entry and exit points.

Palan on one new feature that might be added to the vest in the future:

We will mount an array of speakers on to vest, and offer local gun shot sound. Local speaker array will create an interesting sound space around ears, which could be more realistic than the headphone.

Re: Tactile Vest Gives Gamers a 4th Dimension

I don't remember what they are called, but what I am thinking of is a group of pin-like objects connected together and they start out fluse with each other but placing them over something (some people especially like to place them over their face) and the pins move to different depths, making the group of pins shape around what they are placed over.

Imagine placing those pins inside a vest, all throughout the vest, and being able to manipulate each one, even as a group, mimicking "touch".  They "press in" enough to be felt by the wearing individual.  And they are manipulated as what is "touching" (on screen) moves along the vest.

Now THAT would be an advancement.

Re: Tactile Vest Gives Gamers a 4th Dimension

that was done YEARS ago.

i remember reading about it back before Doom 3 was out when the thing had pre-orders being taken..

better hope that guy doesn't try to sell it :p

otherwise theres another fun patent suit.

Re: Tactile Vest Gives Gamers a 4th Dimension

In the source blog article's comment section, they make reference to the similar vests.

Re: Tactile Vest Gives Gamers a 4th Dimension

yes well now we have it in this comments section as well.

 

tbh i don't normally waste time on running through comments posted to most blogs/news sites/any major site (yahoo/google), let alone ones i'm unfamiliar with.

 

Re: Tactile Vest Gives Gamers a 4th Dimension

No, I mean someone mentioned it in the comments and Palan actually replied back regarding the other vests:

"I have mentioned in the Background section about the TN Games vest. Infact we ordered a few of them and tested it before we started building ours.

I was really inspired by their work and they being the first one’s to build something like this, have done a really good job. I especially liked the way they have got their jacket so rugged, light weighted and easy to setup. Also TN Games did a fair amount of job on the gaming side.

TN Games vest is a pneumatic one requiring external air compressor (a rather noisy device). Also I was interested in doing some research about how we can use electronics for applications like this. We are not comparing our self to TN Games vest as they have made a product, and we are more on the research end yet trying to figure out how we can simulate various effects and studying human’s psychology when using it.

Regarding Interactor vest: never got a chance to try this one so cannot say whats it like. But gathering the information from around web, I understand that it just vibrated and uses a sub-woofer on the back."

Sounds like fun, where can I buy one? does it work with BFBC2?

Re: Tactile Vest Gives Gamers a 4th Dimension

Just get a Buttkicker Gamer and route the game's subwoofer channel through it (easiest with on PC). BC2's subwoofer support is second to none and it works excellently for tactile feedback, especially when firing weapons and close proximity explosions. However the sound design of previous Frostbyte engine BF's was better in some areas (you used to be able to feel tanks drive by via the sub channel).

It's so sad how few games try to make proper use of the sub channel. I've been playing games and music that way for nearly three years and am never going back. The vest however is much more niche and has limited appeal.

Re: Tactile Vest Gives Gamers a 4th Dimension

Dear god, this sounds so damn retarded.

I am an avid game enthusiast, I love the idea of virtual reality, for example, you know what I don't like? Pain. How many people like pain? Do these people think the majority of the world are into sadomasochism like them? Pain is supposed to tell me when I'm hurt, I don't get any goddamn pleasure out of it.

To be quite honest, this is just disturbing, it's totally and utterly wrong. I want more "realistic" games but in the likes of virtual reality, the difference being is that I want a visual representation of what happens when I'm hurt, not a physical or emotional one. I do NOT want to actually experience pain, that's just fucking stupid.

Re: Tactile Vest Gives Gamers a 4th Dimension

That is why, as they said in the article, it doesn't cause pain. More of a surpise tap sensation. I would imagine it is like someone flicking you in the shoulder with their finger. If this hurts, then you probably have other problems to look into.

I personally, as a gamer, think this could be pretty cool as a prototype, but it definitely needs some more dev time. I'm curious how they simulate bloodflow and knife slashes. I can see stabs being simulated, but a slash should need to transfer across a portion of skin.

Re: Tactile Vest Gives Gamers a 4th Dimension

They were saying that for some "wounds" they apply hot/cold the given area.  If they have hot and cold generators throughout the vest, they probably mimic trickling bloodflow by somehow moving the source of the hot/cold sensation.

As in, they have the hot/cold combo where the "wound" is, and then have a moving hot or cold (probably will be one or the other) source.  Since there may be multiple hot/cold generators throughout the vest, then they'd turn them on/off in such incriments to make it feel like the source of the sensation is moving.  Of course, I really have no clue how they really do it, but that would be my first guess.

Re: Tactile Vest Gives Gamers a 4th Dimension

I believe i saw something like that being sold by some company for 200 bucks on the interwebz a couple of months ago.

"How do you think violent videogame critics would react to a Tactile Gaming Vest that allows players to physically feel in-game shootings and stabbings?"

Probably try to mandate it to make kids not want to play them ever.

Re: Tactile Vest Gives Gamers a 4th Dimension

This is great!  Now children can have some conceptual understanding of the consequences of their actions.

or

This is horrible!  The video game industry is training our children to become more efficient killers by desensitizing them to physical pain.

Sora-ChanSo it's just a matter of having better emulation software. If it can be done with a 3DS game, with all the memory and what not it takes up, it can be done with a GBA title through emulation.07/29/2014 - 7:30pm
Sora-ChanOther VC titles for the NES and Gameboy had the same setup where you couldn't access the homescreen without quitting out of the game til a later update when those games were released for the public outside of the founder program.07/29/2014 - 7:28pm
Sora-Chanthe 3DS can, and does, run GBA games, as seen by the founder gifts, which included a number of GBA titles. As for running GBA games and still having access to the home screen, I beleive it's more of the game emulation software needs to be updated.07/29/2014 - 7:27pm
Matthew Wilsonthe 3ds already swaps os's with the original ds. plus I dont think people expect miverse interaction when playing a gba game.07/29/2014 - 6:06pm
MaskedPixelanteBut that's not the issue, the 3DS is perfectly capable of emulating GBA games. The problem is that it doesn't have enough available system resources to run it alongside the 3DS OS, and thus it doesn't have access to stuff like Miiverse and save states.07/29/2014 - 5:45pm
Matthew WilsonI am well aware that it requires more power, but if a GBA emulator could run well on a original psp, than it should work on a 3ds.07/29/2014 - 5:36pm
ZenThe reason the SNES could run Gameboy, or the Gamecube could run GBA was because their adapters included all of the necessary hardware to do it in the respective add-ons. The systems were just conduits for control inputs and video/sound/power.07/29/2014 - 4:51pm
ZenMatthew: Emulation takes more power than people realize to run a game properly. You can make something run on less, but Nintendo...as slow as they are at releasing them..makes them run as close to 100% as possible. Each game has its own emulator for it.07/29/2014 - 4:47pm
Matthew Wilsonkind of hard to believe since the 3ds is atleast as powerful as the gamecube hardware wise.07/29/2014 - 4:27pm
MaskedPixelanteYes, the 3DS has enough power to run 16-bit emulators, but not at the same time it's running the 3DS systems themselves. You could run the games, but you wouldn't get save states or Miiverse.07/29/2014 - 4:04pm
InfophileRunning GBA on 3DS shouldn't be hard. The DS had flashcarts sold for it that added just enough power to emulate GBA and SNES games, so the 3DS should have more than enough natively.07/29/2014 - 3:37pm
