Hololink is a web-based Augmented Reality editor which enables creation of AR through a visual no-code solution. AR created in Hololink is served directly in the mobile browser without the use of an app, making the whole process from creation to end-user 100% browser-based. Hololink gives creators access to: A visual storyboard to ensure a clear overview of all end-user interactions and the entire user journey, making it possible to use rich storytelling. The…

Presto is an open source SQL query engine designed to run queries on data stored in Hadoop or in traditional databases.
Teradata supported development of Presto followed the acquisition of Hadapt and Revelytix.
I only know Hololink from an educational point of view, but as a teacher, I find it easy to use and a fun way to incorporate tech in reports and presentations. My knowledge of the demands in other traits is too little for me to decide whether Hololink is up for the task. For the tasks I've had at hand, Hololink has been a good choice.
Presto is for interactive simple queries, where Hive is for reliable processing. If you have a fact-dim join, presto is great..however for fact-fact joins presto is not the solution.. Presto is a great replacement for proprietary technology like Vertica

As opposed to all other AR creation tools that I know, Hololink does not require consumers to download an app, thereby bypassing the primary problem of creating AR experiences, which is getting people to download an app. Let it be known that native apps are going away, the future is web-based because it is easier.
The Hololink image-tracking, which enables AR elements to be projected upon real-world objects and images is exceptionally good compared to other AR projects that also use image-tracking. In Hololink your buttons, 3D models, and videos do not sail away from the objects that they're supposed to be attached to.
The people working on Hololink are very focused on UX, and the few times that I have had suggestions, they have been very attentive.
Linking, embedding links and adding images is easy enough.
Once you have become familiar with the interface, Presto becomes very quick & easy to use (but, you have to practice & repeat to know what you are doing - it is not as intuitive as one would hope).
Organizing & design is fairly simple with click & drag parameters.

Hololink comes pre-packed with a lot of 3D models there are cases where I would like to write text on models directly, instead of using the annotation function which Hololink provides. It would be easier than having to upload my own 3D models, which is also possible.
Presto was not designed for large fact fact joins. This is by design as presto does not leverage disk and used memory for processing which in turn makes it fast.. However, this is a tradeoff..in an ideal world, people would like to use one system for all their use cases, and presto should get exhaustive by solving this problem.
Resource allocation is not similar to YARN and presto has a priority queue based query resource allocation..so a query that takes long takes longer...this might be alleviated by giving some more control back to the user to define priority/override.
UDF Support is not available in presto. You will have to write your own functions..while this is good for performance, it comes at a huge overhead of building exclusively for presto and not being interoperable with other systems like Hive, SparkSQL etc.

A long time ago I use Aurasma. As I recall it was quite heavy because you had to transfer the Aura from your computer to the student's smartphones through signup on the internet and making them connect to your user with an invitational code, and if it didn´t work it was hard to figure out why. Hololink is just a scan away and you don´t have to connect to any user accounts to see other student products.
Presto is good for a templated design appeal. You cannot be too creative via this interface - but, the layout and options make the finalized visual product appealing to customers. The other design products I use are for different purposes and not really comparable to Presto.

AR is hot right now and thus helps attract people. In the future, the AR-excitement might lessen, but it has clear affordances in terms of communication that will continue to be relevant as long as people have smartphones or google-glasses or the likes.
