Sprout Pro

From EduTechWiki - Reading time: 5 min

Introduction[edit | edit source]

Systems like the Sprout Pro are known as projector-camera (pro-cam) or mediated touch systems [1]. The user can interact with a projection by manipulating something on its surface that is captured and interpreted by a camera.

Wikipedia (dated 2017) described the first Sprout Pro model, “Sprout by HP (stylized as sprout) is a personal computer from HP Inc and released for sale on November 9, 2014. [..] Sprout has dual interactive screens - a vertical touch screen display positioned in-line above a horizontal ‘TouchMat’ display, and also down-facing imaging sensors. The "Sprout Illuminator" serves as a projector, camera, depth sensor and scanner, and projects an image, for example a virtual keyboard, on the TouchMat.[6] For additional input, Sprout includes an Adonit stylus, as well as a Bluetooth-powered set of keyboard and mouse. This enables users to interact with physical and digital content while working. Content can be digitally captured and manipulated in 2D or 3D directly on the TouchMat interface. HP claims that this greatly simplifies and streamlines the creative process.”

HP's Sprout uses “a combination of a physical LCD touchscreen and a downward-facing video projector coupled with a computer-vision-enabled horizontal touch surface (TouchMat) to build a user interface that extends outside the box, allowing the user to interact with the real world in new and exciting ways, capturing and manipulating 2-D and 3-D digital content in a highly intuitive manner.” [2]

As of 2019, a newer Sprout Pro by HP G2 is available. According to HP (retrieved June 12, 2019), “Sprout Pro is a Windows 101 all-in-one immersive learning station designed to enhance hands-on learning, promote collaborative engagement and spark creativity.”

In education[edit | edit source]

(this section needs to be developed...)

HP Sprout (Wikipedia Commons)

Marintcheva (2017) [3] used the sprout to capture physical models built by students using ordinary matrials and that represent viruses.

Nichols (2016) [4] describes how they implemented open science projects with this technology in order to raise interest for STEM fields among youth.

In HCI research[edit | edit source]

Unver et al. (2016) [5] start a demonstration paper by saying that “Projector-camera (pro-cam) systems create virtual environments for remote interaction with audio and video support. However, previous pro-cam systems require custom hardware and thus have not been used at-scale in the field.” and conclude that “the ShareTable application [the authors developed] provides many opportunities to create new knowledge in HCI. We plan to expand the laboratory studies to real-world settings and explore user interaction.”

According to HP[edit | edit source]

The Education Whitepaper (retrieved June 12, 2019), lists a number of educational applications and scenarios. Most of these also could be implemented with more standard setups. It lists potential use cases in different ways. The most important message, in our opinion is on page 3 that reproduce below.


Prepare future thinkers, leaders and innovators

Engage students in new STEAM experiences and 3D asset creation on advanced technology that builds 21st century skills, including:
Coding & Robotics
Extend coding environments with dual multi-touch work areas to show the code on one screen and reference materials or emulations on the other.
3D Exploration
Collect student work in an ePortfolio and create digital models for virtual reality visualizations and 3D printing using the 2D and 3D scanning capabilities.
Blended and interactive content presentations
Showcase physical objects and digital content simultaneously to the entire class. Remotely collaborate with other schools or industry experts with the ability to share up to four feeds.
Video documentation
Create unique flipped classroom videos or empower student-led video documentation with a web-cam, downward-facing camera and dual-screens.
Design & Annotation
Enhance students’ natural ways of drawing, writing and researching with precision digital inking using the HP Active Pen2 on the paper-like HP Touch Mat.
Storytelling
Encourage creative expression through storytelling with stop motion using the downward-facing camera or existing digital content.

Page four then list a number of examples drawn from various disciplines. In both cases, it is not very clear if either teacher or student activities (or both) are described. E.g. under the "Art" section we see “Digitally customize the color or design of clay fired pottery with 3D scanning and image editing software.” I does make sense that technology can be used for either learning through technology or with technology....
