With the tide of intelligent hardware, smart TV is constantly updated, and the market is slowly turning its attention to intelligent projectors. Compared with smart TV, smart projectors have natural advantages in portability, ease of use, viewing effect, etc. Especially in fast-paced cities, projectors are not only for home use, but also play an important role in business activities.
In the field of intelligent projectors, mobile projection and touch projection have gradually become the two major trends in the industry, and have become "standard configuration". Many manufacturers have also started to follow up. This Touchjet Pond we are evaluating is a miniature touch intelligent projector.
Parameter configuration
The Touchjet Pond smart touch projector uses a 4-core Cortex-A7 CPU (RK3128), 1GB RAM+8GB ROM (supporting Micro SD card expansion), a standard projection resolution of 854 * 480, a contrast of 2000:1, lumens: 80, and is equipped with Android 4.4 system, which can project 80 inch projection images. The built-in 3000mAh battery has Mini HDMI Audio Jack, Micro USD interface, body circumference: 28 * 115 * 100mm, weight: 268g.
appearance
The Touchjet Pond intelligent touch projector adopts a box design, and its shell is made of ABS material. It is compact and easy to carry, and its overall weight is only 268g. The Touchjet Pond intelligent touch projector has a projection bulb on the front panel, a sliding power key on the right side of the body, speaker openings on the left and right sides of the body, and Mini HDMI, Audio Jack, Micro USB and power connectors on the back.
The Touchjet Pond intelligent touch projector is equipped with a stylus and a remote control, both of which use two No. 7 batteries. The touch pen is made of metal material and equipped with an infrared switch. The pen tip has an elastic device that can shrink and stretch. The stylus is equipped with an infrared device. Touchjet Pond can project touch by capturing the infrared signal of the stylus.
experience
The Touchjet Pond intelligent touch projector is calibrated by touch before being used for the first time.
In the test of projection effect, we used multiple groups of color blocks and pictures with different color trends to test the projection effect of the Touchjet Pond intelligent touch projector. The result is as shown in the figure. The Touchjet Pond intelligent touch projector can ensure the true restoration of the picture, and the color temperature and color difference are close to the original picture.
In terms of video, the brightness of the Touchjet Pond intelligent touch projector is low, only 80 lumens. With its diffuse reflection projection, the eye protection effect of the Touchjet Pond is better than other projection devices when users watch it for a long time, which is especially important for children and young people.

Baby Cognition (Baby Bus Series App)
Thanks to the support of touch projection, Touchjet Pond intelligent touch projector has natural advantages in early education. By means of touch projection, early education is carried out for children through the application of the early education app in the market. Compared with the purchase of expensive early education learning machines and early education robots, this method is more convenient and fast, abandoning the traditional blackboard teaching, making early education fun and fun. At the same time, the form of parents/teachers' words and deeds is very helpful to children's mental growth.
It is worth mentioning that Touchjet Pond has currently cooperated with Baby Bus, and the subsequent Touchjet Pond intelligent touch projector will directly pre install a full set of authorized Baby Bus App.
In fact, Touchjet Pond, a way of identifying interactive signals through infrared, is not a black technology, but it has the best experience among similar touch projection products used by the author. Its advantages are mainly shown in two aspects: low delay and high accuracy. The touch projection products often change the size of the projection frame and the focus, so it is easy to reduce the accuracy of the touch after multiple use, and even the distortion correction may occur. Fortunately, each correction of Touchjet Pond can effectively adjust the recognition of infrared signals, improve the contact accuracy, and maintain good accuracy after multiple uses. The correction cycle is about 30 times after use.
Summary:
With the brutal growth of mobile Internet, all intelligence is inseparable from "mobile portability", The same is true of intelligent projectors. Before the evaluation, we also Touchjet Pond doubts whether such a small intelligent projector can give consideration to both projection and touch. In fact The performance of the Touchjet Pond did not disappoint us. The 80 lumen brightness can be seen as a compromise between eye protection and mobility. The Touchjet Pond equipped with a 3000mA battery can be projected for up to 2h without power supply, which is enough for us to complete a business meeting and an early childhood education. Touch projection can also be seen as a mobility function. Its addition makes the projector itself more integrated, and the mobile and portable properties of intelligent projectors have been improved.
