Shooting game "Phantogeist" turns AR into social!

As a social AR game, the first-person shooter "Phantogeist" has appeared on Google's Tango project.

The game comes from Trixi Studios, a Chicago-based company where a friendly alien will help you identify the most hateful alien intruders and shoot them in the real world. You hold a smart phone that can use Tango, such as Lenovo's Phab 2 Pro, and carefully observe the surrounding environment. When you find a hostile alien, you fire to it. The biggest challenge is the need to turn around quickly so that you can deal with attackers from all sides.

The reason why Phantogeist is a social experience is because it supports two players at the same time. The partner can also interact with the same creatures you see in the game world, which makes the virtual monsters look more realistic because they share an experience. Sineni stated that "Phantogeist" is not just an AR prototype; it is a complete game with story, partner, survival mode and leaderboard.

The game is similar to "Pokemon Go" (Pokemon Go), both of which also introduce a lot of people in AR games because it inserts virtual characters in the real world environment. But the two are different, because "Phantogeist" is an action game that requires you to turn quickly and shoot creatures coming from all directions.

“This is actually a glimpse into the future. With regard to what kind of e-sports opportunities AR multiplayer games can bring, and how players in the real world can use virtual weapons to compete with other teams,” Sineni said. But it is worth noting that it is the community that determines the components of eSports, not the company.

Phantogeist has a special mode that uses Tango's motion tracking function to perform "full range" dynamic tracking of hostile characters and their surroundings. This is similar to the working principle of the future jailbreak version of VR (virtual reality); that is, players do not need to connect cables or carry any external sensor devices when they move around in a virtual environment.

Most AR games require a tag that players must be able to see on the device so that they can play games within the limited picture. However, in Phantogeist, players can play anywhere and move as they wish. Sineni has been working in the gaming industry for more than 20 years, and has worked for companies such as Viacom and Midway Games. He acknowledges that AR development is tricky, and there is still a great learning process for developers. .

Trixi Studios was just founded this year, but the initial team was few. The studio relies entirely on self-financing. At the same time, Sineni is the co-founder of Phosphor Games, an independent company that had created the hottest game "Brookhaven Experiment" on the Steam and PSVR platforms.

Resistive Touch Screen

Resistive Touch Screen


The outermost layer of resistance screens is usually a soft screen that connects the internal contacts up and down by pressing. The inner layer contains the oxidized metal of the physical material, namely N-type oxide semiconductor (indium oxide), also known as indium oxide, with an optical transmittance of 80% and the upper and lower layers separated by the middle. ITO is the main material used in both resistive and capacitive touch screens. Their working surface is the ITO coating. The outer layer is pressed by fingertips or any object to make the surface film concave and deformed. According to the leading line number of screen, divide again have 4 line, 5 line and much line, threshold is low, cost is opposite cheap, advantage is not affected by dust, temperature, humidity. Disadvantages are also obvious, the outer screen film is easy to scratch, can not use sharp objects to touch the surface. In general, multi-touch control is not allowed, that is, it can only support a single point. If two or more contacts are pressed at the same time, they cannot be recognized and accurate coordinates can be found. To enlarge a picture on the resistance screen, you can only click "+" several times to make the picture be enlarged step by step. This is the basic technical principle of the resistance screen.


Control by pressure induction. When a finger touches the screen, the two conductive layers are in contact at the touch point and the resistance changes. A signal is generated in both X and Y directions and transmitted to the touch screen controller. The controller detects the contact and calculates the position of (X, Y), then works according to the simulated mouse mode. Resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. But because the outer layer of the composite film is made of plastic material, its anti-explosion property is poor, and its service life is affected to some extent.


The resistive touch screen is controlled by pressure induction. The surface layer is a layer of plastic and the bottom layer is a layer of glass, which can withstand the interference of harsh environmental factors. However, it has poor hand feel and light transmittance, so it is suitable for wearing gloves and occasions that cannot be touched directly by hand.
