Foldable Phones and More: Top Tech at Mobile World Congress
The Mobile World Congress, or MWC, is the world's largest yearly event for showing new smartphones and related products. This week's four-day gathering in Barcelona, Spain introduced some interesting new phones and looked to the future of 5G wireless technology.
One of the most talked about happenings at MWC Barcelona was the launch of a new foldable smartphone. China's Huawei launched the device days after South Korea's Samsung officially launched its own foldable phone model. Representatives of both companies showed off their devices. But MWC Barcelona attendees were not permitted to touch or test the new products.
The launches marked a first for the mobile industry. They are the first devices designed to combine a smartphone and a tablet.
Technology experts see such development as an attempt by manufacturers to present a completely new mobile invention after years of only minor phone innovations. The hope is that people will be excited by the new devices and that, in turn, demand and sales will rise. However, most experts expect the market for a foldable phone to be very limited, especially in the beginning.
One major issue for buyers will be cost. Both Samsung and Huawei have priced their foldable models far above any other smartphones.
Mate X and Galaxy Fold
Huawei's new foldable phone is called the Mate X. It will sell for about $2,600 when it goes on sale later this year. Samsung's Galaxy Fold is priced at nearly $2,000 and is expected to be available in late April.
Both devices are designed to work as a smartphone when closed, but as a tablet when opened. The Galaxy Fold has the tablet on the inside of the fold, while the Mate X's tablet covers the outside of the device.
Both models have a traditional smartphone face that operates independently of the tablet. The Mate X display covers the whole outside, so both the front and back faces can be used for phone operations at the same time.
Huawei's Mate X has a larger display than the Galaxy Fold for both phone and tablet operations. The Mate X also folds flatter than the Galaxy Fold. Both models will come in 5G versions.
Several companies also introduced devices designed to work with 5G, the next generation of wireless technology. Some used MWC Barcelona to describe their plans for launching 5G devices and service. In the United States, some companies plan to launch 5G in major cities by this year.
Another product introduced in Barcelona was Microsoft's new HoloLens 2 augmented reality headset. Augmented reality devices project images as holograms onto a user's real-life field of sight. While such devices have traditionally been popular with video gamers, the latest headset seems more designed to help people with their work.
Microsoft's first HoloLens was launched in 2016. Since then, the company has been working to create improvements that users wanted to see. The result is a product that Microsoft claims provides a more immersive experience and fits better on the head.
During a demonstration at MWC Barcelona, Microsoft showed off the HoloLens 2's ability to closely follow eye movements. The presentation also showed how users can feel as though they can actually touch and interact with the holograms. Examples showed a user's ability to play a hologram musical instrument or change the settings of a piece of industrial equipment.
The technology can be used to guide workers through complex industrial or medical processes. It can also be used in office settings to help employees all over the world digitally cooperate on projects as if they were in the same room.
In a statement, Microsoft said it looks forward to many more workers using HoloLens 2 to help perform their jobs better and more safely. "From construction sites to factory floors, from operating rooms to classrooms, HoloLens is changing how we work, learn, communicate and get things done," the company's statement said.

世界移动通信大会（MWC）是全球最大的展示新款智能手机及相关产品的年度盛会 。本周，为期四天的盛会将在西班牙巴塞罗那举行，会上推出了一些有趣的新款手机，并展望了5G无线技术的未来 。
巴塞罗那世界移动通信大会最轰动的事件之一就是新款可折叠屏智能手机的问世 。在韩国三星公司正式推出可折叠屏手机后，中国的华为公司也推出了新款手机 。两家公司的代表都展示了自己的手机，但巴塞罗那世界移动通信大会的与会者不准接触或测试这些新款产品 。
技术专家认为，这种发展是手机产商在历经多年小规模手机创新后，推出的一项全新的手机发明的尝试 。他们希望这些新设备能激发人们的兴趣，进而提高市场需求和销量 。然而，大多数专家预计，可折叠屏手机的市场将非常有限，尤其是在初始阶段 。
消费者面临的主要问题之一就是定价 。三星和华为公司的可折叠屏手机定价远超其它智能手机 。
Mate X和Galaxy Fold
华为公司的新款可折叠屏手机为Mate X，这款手机在今年晚些时候上市的售价约2600美元 。三星公司的Galaxy Fold的价格接近2000美元，有望于4月底上市 。
这两款手机折叠时可作为智能手机使用，展开后可以作为平板电脑使用 。Galaxy Fold手机的折叠内侧有平板电脑，Mate X的平板电脑覆盖在手机的外侧 。
两款机型均采用了传统的智能手机界面，独立于平板电脑运行 。Mate X的显示屏覆盖了整个手机外观，因此手机正、反面可同时作为手机使用 。
华为Mate X手机及平板电脑的显示屏均大于Galaxy Fold 。折叠的Mate X也较Galaxy Fold平整，两款机型均使用5G通信技术 。
其他几家公司也推出了5G手机，5G是下一代的无线技术 。一些公司通过巴塞罗那世界移动大会介绍了新推出的5G手机和5G服务的计划 。美国一些公司计划今年年底前在主要城市推出5G技术 。
该大会推出的另一款产品是微软公司全新的HoloLens 2增强现实头盔 。增强现实设备将图像作为全息投影投射到用户的真实视野中 。虽然这类设备传统上一直备受视频游戏玩家的追捧，但是这款最新产品看上去更像是锁定办公人群 。
2016年，微软公司推出第一代HoloLens 。自那时起，该公司一直致力于创造出用户希望看到的提升 。这款产品应运而生，微软称其提供了更加身临其境的体验，头部佩戴更加舒适 。
在巴塞罗那世界移动展会期间，微软公司展示了HoloLens 2跟随眼球转动的能力 。这次演示还展示了用户如何感受到真实触感并与全息图进行交互 。示例显示用户能够演奏全息乐器或改变某工业设备的设置 。
该技术可用于指导工作人员完成复杂的工业或是医疗过程 。它还可以用于办公用途，帮助世界各地的员工进行项目数字化合作，仿佛同处一室 。
微软公司在一份声明中表示，期待更多办公人群使用HoloLens 2帮助他们更好、更安全地完成工作 。该公司的声明称：“从建筑工地到工厂车间，从手术室到教室，HoloLens改变了我们工作、学习、交流以及做事方式 。”
