Last month (April 16) Albrecht Schmidt visited UNH and the Project54 lab. Albrecht gave an excellent talk introducing some of the research problems in pervasive computing and specifically touching on the latest results from his lab, which were just published at CHI 2010 [1, 2]. I was especially interested in the work on helping users find the last place of interest on a map quickly. Albrecht and colleagues track the user’s gaze and when the user looks away, they place a marker (or gazemark) on the map. When the user looks back at the map she can start where she left off: at the place of the marker. Clearly this could be very useful when looking at GPS maps in a car. In such a situation the driver has to keep going back and forth between the map and the road and you want to minimize the time spent looking at the map (the road being the more important thing to look at!). The gazemarks introduced by Albrecht’s group may help. It would be interesting to conduct a driving simulator study with gazemarks.

After the talk Albrecht spent about an hour with students from the Project54 lab and those in my Ubicomp Fundamentals course. This was a more intimate setting for conversations about Albrecht’s research. Finally, Project54 staff and students spent a couple of hours discussing Project54 research with Albrecht – our work on handheld computers, on driving simulator-based investigations of in-car user interfaces and our budding efforts in multi-touch table interaction.

I am grateful to the UNH Provost’s Office for helping to fund Albrecht’s visit through a grant from the Class of 1954 Academic Enrichment Fund.

In a front page article of the March 11, 2010 edition of the New York Times Matt Richtel discusses in-vehicle electronic devices used by first responders. Based on a number of interviews, including one with me, Matt gets the point across that interactions with in-vehicle devices can distract first responders from the primary task for any driver: driving. The personal accounts from first responders are certainly gripping. Thanks Matt for bringing this issue to the public.

Enter Project54. According to Matt “[r]esearchers are working to reduce the risk.” He goes on to describe UNH’s Project54 system which allows officers to issue voice commands in order to interact with in-car electronic devices. This means officers can keep their eyes on the road and their hands on the wheel. The article includes praise for the Project54 system by Captain John G. LeLacheur of the New Hampshire State Police. The Project54 system was developed in partnership with the NHSP and almost every NHSP cruiser has the Project54 system installed.

Both the print and the online versions of the article begin with a picture of the Project54 in-car system. This great picture was taken by Sheryl Senter and it shows Sergeant Tom Dronsfield of the Lee, NH Police Department in action.

On Wednesday and Thursday, Oskar Palinko, Mark Taipan and I participated in the NIJ CommTech Technical Working Group meeting. On Wednesday I gave the presentation below reporting on our lab’s progress.

On Thursday we participated in the meeting’s demo session. We demonstrated the advantage of using voice commands to control a police radio over using the radio’s buttons. We used a single-computer driving simulator and a radio setup. Of course the first driving simulator experiment we published investigated this effect [1]. We also demonstrated accessing a remote database using the Project54 system running on a Symbol handheld computer. We expect that, once we get approval from the NH State Police to deploy such devices (NHSP is responsible for data access for all officers in the state), they will be a big hit with local departments.

One of the many people we had a chance to talk to at the TWG meeting is Gil Emery, Communications Manager at the Portsmouth, NH PD. Gil was interested in the handhelds and we may be able to work with him on using these handhelds as cameras that allow tagging pictures on the spot and then using a cellular network to transmit them to headquarters. This work would build on Michael Farrar’s MS thesis research.
